Our ZZP replacement ball joints are designed to be a drop in replacement for your Ecotec car. We worked to ensure our ball joints are held to a specific tolerance that previous aftermarket control arm companies could not be held too. 

We offer our ball joints in both the 19.5mm and 20.5mm size that is found across the Ecotec/Delta platform cars. The LSJ Cobalt SS, Saturn Ion Redline, and base model Ion/Cobalt/HHR's will use the 19.5mm ball joint. The turbo LNF Cobalt SS and LNF HHR SS are the only models that will use the 20.5mm ball joint.

Other vendors list that their control arms fit the LNF models but we have found that they are incorrectly sold as the smaller ball joint size almost all of the time. Purchase from ZZPerformance to ensure worry free parts and installation. Fully assembled with ball joints, control arm bushings, and trailing arm bushings. 

We include both bolts and locking nuts as well as buck rivets for your choice of installation. 

LSJ 19.5mm fits: 05-07 Chevy Cobalt SS, 04-07 Saturn Ion Redline, 05-10 Chevy Cobalt LS/LT/LTZ/Sport, 06-11 Chevy HHR LS/LT/LTZ, 04-07 Saturn Ion Level 1/2/3.

LNF 20.5mm fits: 08-10 Chevy Cobalt SS 2.0L, 08-10 Chevy HHR SS.
