Product Description
SuperPro TRC1038 is for Crosstrek owners replacing worn factory front lower arms who also want a more controlled front end. The kit arrives with the polyurethane bushings and upgraded ball joints already fitted, eliminating the need to press bushings into old arms or assemble separate parts before installation.
The SuperPro bushings are designed to reduce the flex associated with OE-style rubber bushings, helping the arm hold its intended position more consistently when braking, turning, or driving over rough pavement. It is an upgrade that makes sense for a stock-height Crosstrek, a lifted trail vehicle, or a daily driver with tired original suspension parts.
