Construction & Design

The SuperPro Trailing Arm Upper Bushing Kit features a one-piece polyurethane bushing design that replaces the original rubber or factory-style bushings. The polyurethane material is formulated for maximum durability, resisting cracking, tearing, and deformation over time. The bushings are CNC-machined to precise tolerances, ensuring a snug fit that maintains suspension geometry and reduces unwanted play.

The kit includes metal sleeves and housings that are TIG-welded or pressed into the polyurethane bushings, providing a secure and stable mount within the trailing arm assembly. The design promotes even load distribution and minimizes stress concentrations, which can lead to premature bushing failure. The result is a suspension component that enhances handling response, reduces noise, and extends the service life of your vehicle's suspension system.

Installation & Fitment

The SuperPro Trailing Arm Upper Bushing Kit is designed for a straightforward, bolt-on installation. It requires no cutting, drilling, or complex modifications. Basic hand tools and suspension knowledge are recommended for proper installation. The kit is a direct replacement for the original bushings, restoring the suspension's integrity and alignment. For best results, it is advisable to inspect and replace other suspension components simultaneously to ensure optimal handling and safety.
