I am at the point where I am ready to start tearing into my front suspension, and replacing it all with new components. I am trying to figure out what parts are best to use, I did a comparison between Moog and Open tracker parts, and this is what I came up with as a good starting point:
Open tracker suspension part pricing
Front Suspension
Upper control arm: $225 pair (90 degree zerk, rebuilt shaft kit, welded tab for security)
Lower control arm: $160 pair (actually made by moog)
Roller spring perches: $199 (Not really comparable, one of a kind)
Coil Springs: GT 350 – 1” lower- : $93.95
560 Lb - 1” lower- : $82.95
750 Lb - Track - :$ 93.95
Shocks: Grab –A-Trak (Nitrogen charged) $59.00 a pair ( $59.00 rear pair)
KYB Shocks: Gas-a-just (Very Firm Ride) $ 90.00 a pair ( $90.00 Rear pair)
** Bilstein Shocks – Street Valving: $ 164.00 a pair
Sport Valving: $ 278.00 a pair
Track Valving: $ 324.00 a pair (Bilstein Rear Shock: $ 199.00 a pair)
Total with highlighted items above: $ 841.00
Moog Parts
Upper control arm made by MOOG part # RK621428: $145.98 a pair
Lower control arm made by MOOG Part # CK8035: $73.78 a pair
Spring perches “non roller” : 13.73
Coil springs “stock” , made by MOOG : $59.79
Shocks - KYB Gas adjust: 32.79 pair ( Front & Rear)
Total with above parts: $266.28
There is a bit of a differance in price, just trying to find the best medium. I do like the idea of the roller perches, but are they really that amazing? Would I realy notice the differance>?
I have had Bilstein shocks on an Pre runner truck I owned, and I know the quaility is great, any feedback here?
I also plan on replacing most of the steering components as I go forward as well, but thats a differant ball of wax.
I also know you get what you pay for, and only want to do this one time, the right way! Thanks in advance.

I went with the Open Tracker uppers because they take the time to set the arms up properly and for the base price you can also get the pivots offset by 1/8" for a caster gain (I think this has to be requested when ordering). You can do these mods on stock Moog uppers but the cost difference was minor and it was one less task for me. I rebuilt my own lowers using the bearing kit from OT and converted to threaded ball joints from various parts houses. The threaded/replaceable ball joints were not necessary but I was already into it. I would probably opt for the stock Moog lowers and take the savings and potentially apply that to adjustable strut rods to gain a little more adjustment but these can also be added later. What year is your car? For 67 and later I don't think the adjustable strut rods are as necessary. The roller perches appear to work from what I read. I bought a set from OT. The last set of stock replacements I installed became rock hard after only a few years and ended up tearing the mounting pads on my UCA's so I didn't want to go down that path again. My car will probably not see any driving conditions that matches the components that I am installing but I hope to do this only once.
I can't comment on springs but to throw another variable into the mix you may want to look at relocating the spring perches out 1/2" to 3/4" which allows you to run a lighter spring. Since you are assembling all new, this would be easy to do. I think OT can help you with this as to necessity and/or benefits.
I plan on ordering my shocks from OT when the time comes primarily because I have heard positive feedback on the valving and performance for street driving so that you can preserve your teeth on rough surfaces.
A lot of suspension improvements are lost if the shock towers are not controlled so ensure that you have appropriate braces added.

A question worth considering is "How will the car be used?" My 65 is a pleasure car and will never see any track time. I replaced steering and suspension components last summer. With advice from FYIFord, I went with all Moog parts, and found Rock Auto the cheapest place to get them. (Don't forget to use the discount code that RA posts quarterly under the swap meet section of the forum, here) For UCA's I rebuilt my own. If you have the time and patience to fiddle with the shafts & bushings, AND your original uca's are not beyond repair, it's kind of a fun job. I bought the Moog lca's. If you are can weld a bit, you can box the lca's yourself. A forum member, here, gave me a good deal on some "F15Falcon" roller perches (F15 has posted some DIY tips here, and on the old forum). Well made, and suspension travel is smooth, without bind, when up on the jack stands. The original style perches have bind, by design, and reportedly wear out quickly. Shocks; I bought the Bilstein Street shocks. I really like them. Springs; I cleaned, painted, and reinstalled the 49 year old GT springs. I like the ride, and height. I also replaced the strut rod and sway bar bushings and end links.
You did not mention anything about your rear suspension. You will need to address the rear, to get the car to ride and handle well. I went with the GrabATrack mideye 4 leaf springs, and got the Scott Drake GT shackles & bushings. (I bought the Moog rear spring bushings, but they did not fit into the GrabATrack springs) The GT shackles make spring installation easier, if you have dual exhaust through the rear valance.
Like GPatrick mentions, an export brace will keep the shock towers spaced firmly. I had to use a port-a-power to spread mine, after years of sagging. I am real happy with the way my car rides and handles for the cruising I do. This summer I will rebuild the steering box, and I expect it will drive like it did 50 years ago, lol.
I have a full set of the Grab A Track or KYB (can't remember which, right now) gas shocks that are new in box, left over from a different project. If you have interest, send me a pm.

My car is a 65 convertible A code Gpatrick, I often make the mistake and assume folks on here have seen my posts,and are therefore allready familiar with my car. I have looked at the adjustable strut rods and have also seem them highly recommended to other folks doing similar upgrades, so I will definetly consider them, along with roller idler arms.
As far as what I will be using the car for, I anticipate a lot of street time, mostly cruising, maybe some longer trips potentially. I have thought about doing some track time but I dont really have a strong desire at this time, but that may change once I get behind the wheel and want to see what the car can do? Such is life....
I imagine rebuilding my UCA is an option, and I see OT offers a DIY roller kit, but for the itme and price, I will have to keep thinking about that one. I am strongly considering Bilstein shocks, have off roaded a truck I had with them and they never let me down.
When you mention "Bind" is that just in referance to the part maxing out on articulation or travel? Not exactly sure what the bind your refering to means, is it nescessarilly a bad thing if it is by design?
I also plan on uprgrading my front brakes while I am in there, converting to disc as I have allready purchased the take-off 2014 Mustang GT 13.2 Rotors/Calipers for Rousch racing, and have to still order some components form Mustang Steve ( PV, brackets, Master Cylinder). I had only mentioned the front suspension as I am trying to tackle one thing at a time, will eventually do the rear suspension (leaf springs, shocks, and possibly disc breaks but not 100% on the disc yet) the car had sat for over 10 years prior to me owning, and I have never driven it. I just think everything needs to be addressed one way or another.
I would like to add dual exhaust eventually, through the rear valance would be desired so thanks for the input on the GT shackles, I know there is very little room back there to work with.

When you try to turn the shaft of an oem style perch with your fingers, there is a fair amount of resistance to movement there. In my mind, it may well help to dampen the travel of the suspension, but the resistance is caused by friction between the moving parts (steel shaft in rubber bushings) and any old perches I have seen have wear at those friction points. The roller perch shafts rotate freely, and because they are sealed bearings, they are supposed to last longer, and are rebuildable. I only have a few hundred miles on mine, so I am not the poster child for longevity.

When I replaced my upper arms a couple years ago I went with Moog stuff. I like the roller perches because of the way it lets the front lift when I hammer it. Its a smooth rise and return. I have the old 50 year old front springs with a full coil removed. Nice soft ride and the stock front shocks keep it from "motor-boating" up and down. Biggest improvement was the monte carlo bar and the one piece export bar. Really made a difference in how it corners and handles. On ramps and off ramps FEAR ME when I use them!!
When doing the Shelby drop..it lowered my front a good inch or so. I did NOT have an inch to spare with my cut coil springs and long tube headers. I installed a pair of 1" poly spring blocks(looks like a thick doughnut) and that brought the front back up so MOST speed bumps are no problem.
The combination of all the above + the Shelby drop makes my 66 a lot of fun to drive/cruise. I wouldn't change a thang!

PS........I thought my original manual steering box was needing replaced. I removed the bolt/plug in the top of the box and added some grease.....almost an entire tube!! Made a HUGE difference in the steering.(Thanx Bob C) Still have the original box. Think about how hot that grease in the box gets...so close to the headers. Its no wonder it just needed grease!

Stay away from the 750 springs. I run 620s and KYB shocks and its a very good combo. The ride is stiffer than stock, but not overly harsh. The handling is great, even with the puny 7/8" front sway bar that I never got around to changing. No A-arm drop either, just poly bushings throughout.
I echo TimC's comments about deciding what you want to use the car for. It gets tempting to dial in a track ready suspension, but you will unlikely enjoy the firm ride over time on the street. We're planning on a driver that handles more like a modern car.
My project is essentially a nut and bolt restomod of my 1967 Coupe. I went with a Grab A Trak setup all the way around and switched from drum to disk brakes on all four corners. Up front, I have Scott Drake upper arms and new lower arms, roller perches, 620 coils Grab a Trak shocks and a 1" anti-roll bar. I'm going with adjustable strut rods based on everything I've read. Out back, I've got Grab a Trak 4.5 mid eye springs and KYB shocks.
I don't know about ride height yet, because I have to get the drive train, glass and interior back in the car. I'd imagine some coil cutting up front, and maybe 1" lowering blocks in the rear will be fine tuning elements.
Separate from suspension, I'm adding a Unisteer rack and pinion setup.
Good luck!!

Unless you want it to ride like a rock I would do the following
buy 480 springs . . stock are around 215 . . you can lower the car with them if you want.
Shelby drop if you want
drake makes free moving urethane perches for less than than rollers.
stock strut rods.
tcp strut rod bushings.
Viking shocks with separate compression and rebound adjustment.
135 lb rear springs, if you want it lowered buy reverse eye type . . stock are around 95.
1“ front sway bar.
Black or red urethane bushings.
Npd deep channel shock tower brace for non Shelby.
Rallye bar
Mckay Norris or moog parts.
Camber negative .3 degrees
Caster positive 2 degrees
Toe in 3/16”

Check out the tech tips on adjustable strut rods Jdorski built his own so did I you don't need a machine shop to do it the parts and time around a hundred bucks, go with the moog stuff if your not racing, Check Daze's site for roller spring perch diy kits, opentracker makes a sweet roller pitman arm buy it, reduces steering effort like wow on manual steering won't hurt on power either, listen to the 65/66 guys for spring suggestions, Shelby drop see Daze, a one inch sway bar and your cruzin'.Stay away from polyurethane less you like a stiff ride stock rubber worked well for ford.

it is a roller idler arm not a roller pitman arm and it reduces steering effort a little but also reduces "automatic return to center" of the steering wheel which some people absolutely hate and some do not.

I didn't know any better and ordered the Dynacorn upper/lower control arms, but got the heavy duty ones, and haven't seen much discussion about them. The uppers have a suspension bushing in them and the lowers were reinforced underneath. I see they have the lower reinforcements separate:
1965 Ford Mustang Control Arms
I spoke to a local shop who told me that the roller bearing perches aren't lasting, and recommended the newer Scott Drake high performance perches, I have some on back-order..
The upper Dynacorn heavy duty have a suspension bushing.
There is just a cap on the end, nowhere for a grease fitting.
This is the Monday morning version of the lower control arm with a missing spot weld, good place to do some welding practice, also the Drakes I saw had a u shape on the bottom lip which should be stronger than just an L, but the Dynacorn material seems pretty hefty:
Offline
Another question I have is that the adjustable strut rods are used to 1) provide adjustability for front-end geometry, and 2) to provide a free range of motion for suspension travel.
In the process it sounds like you lose a lot of the ride quality because of the road vibration being transferred direct to the frame.
After looking at all the $300+ options I am wondering why not just put in a couple of swedge tubes and be done with it? #1 is important to me, and #2 is a harsh luxury that won't affect me much for the street? This would add up to about a $40 to $50 upgrade with buying the 3/4" dies.
Yet to find anybody that did the swedge tube only.
Offline
The strut rods are adjustable to a point. The issue is that you usually can't get enough positive caster in the front end with the factory hardware.
A roller idler bearing will basically eliminate return to center. The torsion of the rubber bushing in the idler is all the really makes it spring back. I would not recomend this for a street car.
Poly bushings are not overly harsh depending on the durometer. Usually good ones have some complaince. Rubber is cushy, but dry rots, wears out, and fails under hard performance use. It was good enough for Ford in a stock car, and largely because it was cheap. Keep in mind that a lot of vehicle design is cost based compromise. Just because Ford did something doesn't make it the best, often it just makes it the cheapest.

Yep forgive me I'm still hungover its roller idler arm.

FYI,
If you're looking for shocks I see Street or Track has his bilstiens on sale thru the end of January.
Offline
I'd be curious to hear opinions on the Bilsteins from people who run them. Past expereince has led me to shy away due to an overly harsh ride caused by overriding the springs. The KYBs were the gold standard years ago, and after 20 years they still wrok great in my setup.

We have never had a return on a roller spring perch in the 11 years we've been selling them. I know one set that has over 90,000 miles on them.
The bearings can be replaced in just a few minutes if there was an issue.
With the roller idler arm, we have found the return to center is brought on by the caster angle more than the rubber bushing in the idler arm. The cars didn't have enough caster from the factory and it's preffered to have more caster with a performance driven car. When the cars have more caster than the factory settings allowed, the steering wheel returns to center quite well.

When the guy said he had bearings go out after 4 years, I questioned him because I had not read of any issues. He had multiple cars in stages of resto and the work looked quality, but he must have had some cheap knock-off perches.
Consider it hearsay.

Adding a significant amount of positive caster would definitely improve return to center. I hadn't considered that. Only possible by moving stuff around from the factory positions though.

yes but unfortunately this is a band aid to compensate for this issue and contrary to some peoples belief, a lot of caster is not always the best thing . .

Especially if you don't have power steering. It increases steering effort quite a bit. You also have to worry about the operating angles of the balljoints, and potentially putting the bushings in the LCA into a bind condition. Everything in a car is a tradeoff, and susppensions are no different. I remember following David Frieburger's quest to have a 9 second street car in Car Craft years ago. Ultimately its a decision he regreted. The car wasn't a good street car, and it sacrificed too much at the track. One of the compromises was to keep manual steering (for weight reduction), but he shortened the strut rods to give it 9 degrees of positive caster. It was necessary to keep it straight going down the track at high speeds, but it meant you had to be a titan to steer the thing, even with skinnys on the front. In the end, he could have had an 8 second race car that had to be trailered for a lot less money and with no compromises.
REMEMBER!!! When posting a question about your Mustang or other Ford on this forum, BE SURE to tell us what it is, what year, engine, etc so we have enough information to go on. |
