69 Camaro subframe

[Bwheeler287]

Just chiming in here because I just did the Tru Turn On my 68 Camaro. I did the Tru Turn and dropped spindles. The tire clearance is great but I'm only running 245's on 8" wheels. I'm running 5" of backspace on the wheels.
I also had my factory steering box rebuilt with the close ratio gears. I love how tight the steering is.
I would really look at the ridetech stuff. Great quality and great customer service.

Where did you have the steering box work done?

I deleted the whole discussion on Corvette hub bolt circle dimensions. Lots of the early info was wrong.
To Summarize, C4, C5, C6 uses a 120.65mm bolt circle which is 4.75"
Fifth Gen Camaro uses 120mm, and C7 Corvettes may also be 120mm which is just 4.7211"

Thanks for clearing that up.

If I was to stick with the stock sub and go with the tru turn, a steering box upgrade would be a must. What is everyone's experience with that?

What's good, what's bad and what works well? There seems to be a wide variety of options as well as prices. Most seem to be based on the 600 box, is that correct? I have a factory power box but would be unsure of the series. Research on this site has shown sending it out to Lee and have them build it up is an option.

I have also come across one (cannot remember which) that said it has rack and pinion style construction and valving rather than a recirculating ball type construction. What's the skinny on that?

The gears and piston are not much different, the control valving is supposed to be "better" perhaps with less play.

I use these a lot without issue and the price is right at 387 bucks and free ship

Summit AGR 12:1 box

I have one in my own car also for 10 hard racing years now

I'm glad you have good luck with it, that's good to hear because I have read some pretty old threads about guys having problems with them and always wondered how well they performed currently

Definitely lighter on the wallet than some $700+ dollar ones
