TCI Rear Suspension

[Jrthom21]

Hello all, new to the forum. Building a 68 Camaro and updating the suspension. I want to get away from the leaf spring rear end. I have a limited budget and have found the TCI torque arm setup with coil overs.
Does anyone have any experience with this setup? Do you have any recommendations that I should consider for the rear end?

Thanks in advanced for the help.

I plan on running this rear setup. Check the tci website. They have a link to an install article. Also, the tci 68 camaro is pretty fast...

Hello, I'm currently building a 69 Camaro and the shop I have it at has built a custom rear suspension for it and plans to duplicate. It's a 4-bar system with rails that run all the way to the rear allowing me to easily install the coil-overs, swaybar, and a custom gas tank. I purchased the TCI complete front sub-frame ans was able to ride in their Camaro at Pleasanton at the last Goodguys show. I will admit that if I had ridden in it sooner I believe I would have purchased their rear set-up as well. It's very different and seems to work excellent. I think the 4-bar is great for handling power but the TCI will make a better all around handling car in my opinion. I'm running an LS1 with T56 and expect to be around 500-550hp once I install a Magnacharger. I'm just looking for a good driver with plenty of power when you want it. Also running a Fab9 rear with Strange drop-in, 35 spline Moser axles. I'm still over a year away from completion. The shop my car is at (www.theshopnorcal.co), also has a 69 (stock SS car with 350 4-speed), to assemble for sale, already painted the factory Dusk Blue, and a 67 and 68 that he wants to build like mine, both will be built to sell if you no anyone interested. We are in Sacramento, CA.

We offer the most well-balanced, easy to install rear suspension available for the 67-69 F-Body Platform. Our kit is a simple to install bolt on kit that can be installed using standard tools. Using our proven track record in torque arm development and application we developed a torque arm conversion kit that brings modern suspension technology to these cars.

Here is a VERY informative tech article written by our R&D manager explaining what it does:

The guys at V8TV recently shot a great install and results video of our kit on a customers 71 Firebird:

Here is a video of a customer who got 2nd place in Street Machine Class at Kansas Good Guys last Summer. He was running air over shocks built for ride quality not performance and had not adjusted the roll center via Watt’s Link….. he should be able to cut some major time off just by addressing these issues.

Here is a install article that Super Chevy did a few years back:

We offer a Torque Arm kit for the stock GM 10 & 12 bolt rear differentials and a kit for guys who want a Ford 9". The Ford 9” kit includes a bare Strange housing for $600 more than the 10 & 12 bolt kits. Take a look at the link below detailing an install that a Pro-Touring member completed with our Ford 9 in. kit in his 1973 Firebird:

The owner of the 73 Firebird made the following comments to us:

“I've put 4000 miles on it and drive it at every possible opportunity. No track time yet due to other commitments but there is always this spring. I still have to play with the shock settings to soften up the launch, it is just incredible how the car reacts from the factory setup. The rear stays planted no matter if it's in the corners or straights. I've had ZERO issues with the entire setup, I'm EXTREMELY HAPPY with it. I hope to get some auto-x & road course time this spring.”

I still can't thank you all there enough for everything, the kit really changed the car into a ride that I truly enjoy driving.”


Our entire 67-69 suspension system was recently showcased on Two Guys Garage as well:

I just got my TCI rear suspension kit and will be posting the build on my link below in the signature. I'm a bit behind in updates but I can tell you I've been extremely happy with my whole experience with TCI and they really treat their customers well. My set up, in my humble opinion, looks killer and has gone together very smooth. TCI is a first class group of guys and I highly recommend them. Check out my build thread and keep an eye for the rear suspension install coming soon.

Here is my current status and you can see the TCI rear components stacked right behind the front clip.

TCI is so good to work with and super helpful on the phone. Todd, Was your rear the torque arm set up? Did you use DSE mini Tubs? I cut the original tubs out and then fit the suspension in. Dodged a bullet here, as DSE cut measurements vs. TCI's coil over x-menber were different. I think it would have been impossible if had welded the tubs in. Anyone using this combo in the future, definately check it out.

I have no direct personal experience with a torque arm rear suspension, except for the fact that I've raced against the TCI Camaro a few times...VERY inpressive. I've also raced against the Speed Tech Nova...also impressive. The TCI system comes standard with the RideTech coilovers. They are optional on the Speed Tech system.

Due to my obvious bias, I cannot let you forget about the RideTech bolt-in triangulated 4 link. This is what is under our 48 Hour Camaro and it is pretty fast.

I'm in the process of installing my mini-tub kit currently and then I'll be installing my TCi torque arm kit. When I did a quick read through of the instructions they do show that there is a different measure for mini-tub cars so I'm not sure where you had an issue, see link below. Can you explain what happened?

Any updates???

I finally got my rear suspension under the car. I did encounter one last problem before being final. My rearend was 55.5" AF to AF. TCI now has spec'd it as 54.75" when using DSE mini tubs. I spoke with Evan @ TCI and they gladly build me another housing and cut my axles free of charge. Can not beat there service and helpful support. I had them cut it to 54.50" and I really like it. Very little trimming with a 12" wheel, 335/30-18 on a 5.5" backspace. Again. I have not put the tubs in, only cut them out. You have way more access and see the clearance issues. In my mind the tubs should go in last. Drop the shock crossmember and go.
