need to get a pair. who has the best prices. a little on the hard to find as everyone carries the regular stuff.

Im pretty sure all HHRs have the same part number on the control arms, every source Ive seen anyways. Id recommend to get some with the bushings already installed.
A good upgrade from powellraceshop, they are a much better part.

the ss is a special part different than LS

only difference is the ball joints..

x2 - cause the SS has a different steering knuckle that uses the bigger lower ball joint.

Look at the Ebay. I have had good results from Prime Choice and a couple of other vendors there.

If you just want bushing your local auto parts will probably be best on account of shipping etc.

I swapped out the ball joints ( Moog ) and the bushing GM parts direct , on the original LCA's on my Lt a few months back, but I did see SS units on several sites
