Product Description

The SuperPro SPF5707K Rear Upper Control Arm Outer Heim Joint Kit is a precise suspension replacement designed for the rear upper control arm of select Pontiac G8 and Chevrolet SS models. These vehicles use a heim (spherical) joint where the upper control arm attaches to the knuckle - a critical pivot point in rear suspension geometry. 

Over time, factory joints can wear, leading to increased deflection, sloppy handling, and uneven tire wear. The SPF5707K kit replaces worn outer joints with high-quality components that restore rear suspension precision and improve overall vehicle stability and response. 

Designed for direct fitment on 2008-2009 Pontiac G8 (Base, GT, GXP) and 2014-2017 Chevrolet SS (Base), this kit is an efficient and cost-effective solution compared with replacing the entire knuckle assembly. A proper rear wheel alignment after installation ensures optimal handling and tire performance.
