shitty GM ones are bending and giving me a noticeable thrust angle. what supplies do I need to replace these (besides the arms obviously) and which aftermarket arms do you guys recommend?

 

A lot of people like UMI LCA's. I went with the poly/rod one. BMR also makes good ones. You can order a new bolt kit with them. Thats really all there is to it. Get adjustable ones whichever you go with

 

You can re use your factory bolts, I did.

Any brand LCAs would suit you find, they all follow the same design "template". Some companies offer other features though(Spherical rod ends, boxed arms, tubular arms).


Adjustables are good if you have a 12 bolt/aftermarket rear end. If your a beginer in the LS1 world and have a stock rear end I would get some non adjustable ones cause they are cheaper and they do what they are supposed to.
