Our ZZPerformance LNF steering knuckles are direct replacement for OEM knuckles, also know as spindles. The OEM knuckles for the LNF Cobalt SS and HHR SS have long been discontinued and, until now, aftermarket replacements were not available. Our knuckles are forged aluminum. 

These knuckles are based off the OEM units, meaning no modification is necessary for installation. 

2 year standard ZZP warranty. We will not warranty if the incorrect ball joint is used. These knuckles accept the 20.5mm ball joint. Some aftermarket ball joints state they fit the LNF cars, however they are typically undersized at 20mm. 

Replaces OEM part numbers 25923941 and 25923942. 

Fits: 2008-2010 Chevrolet Cobalt SS 2.0 and 2008-2010 Chevrolet HHR SS 2.0. Some early 2008 HHR SS models may have used the smaller LSJ style ball joint. Please contact customerservice@zzperformance.com if you have any questions.
