Upgrade your older SPC arms to the latest design with this complete bushing retrofit kit. These xAxis joints feature free pivoting inner balls to maximize droop travel and are greased & booted to protect against contaminants. The bonded rubber outer shell is designed to maintain factory noise, vibration, and harshness (NVH) measurements. The kit includes four bushings, nylon sleeves, washers, and the press tool needed to install the new bushings in your arms. On a budget? We still sell our SpecRid bushing kit for these arms, see part number 25476. Note: This kit requires a shop press to install.
