SPL - Lower Control Arm Replacement Stud Kit


Our stud replacement kit is available for those requiring replacement hardware for their front lower control arm per our TSB 23-01. It includes manganese phosphate coated hardened chromoly steel shank studs, 304 stainless steel adjustment spacers in 1/8" heights, 304 stainless steel adapter spacer bushings, and plated Nylock nuts.  This new design allows for Roll Center correction to be adjusted without removing the stud from the knuckle, an improvement from the previously used socket head cap screws.

We're providing these kits at our cost to both end users and dealers.
