The CPP Adjustable Rear Upper Trailing Arm Kit, part number 7887RTCA-UB, is a rear suspension upgrade for 1978-1988 GM G Body applications. This kit includes black adjustable upper trailing arms designed to improve rear axle location and allow pinion angle adjustment during suspension setup. These upper arms are a strong upgrade for restoration, street performance, and handling builds where rear suspension geometry tuning is needed, while maintaining a clean black finish.
When it comes to upgrading the suspension on a classic car or truck, quality matters. From improved handling to long-term durability, the parts you install play a major role in how your vehicle performs on the road. That’s why Classic Performance Products (CPP) focuses on designing and manufacturing many of its suspension components right here in the USA, using modern engineering tools and robotic welding technology.
