Product Description

The QA1 5254 Adjustable Upper Rear Trailing Arms are engineered for GM B-Body vehicles from 1971 through 1996 that demand improved rear suspension geometry, durability and tuning flexibility. These arms replace the stock upper trailing arms with a high-quality aluminium adjustable unit featuring advanced bushings and fine-tuning capability - ideal for lowered cars, pro-touring builds or any rear suspension upgrade.

By allowing precise pinion angle adjustment, the 5254 arms help mitigate drivetrain vibration, reduce wheel hop under load and preserve alignment under heavy acceleration or cornering. The use of graphite/polyurethane bushings offers a significant improvement over the original rubber bushings - yielding firmer response, longer life and reduced deflection. Because the arms are sold as a pair and bolt into factory mounting points, they provide a straightforward upgrade path with tangible performance benefits.

Installation is straightforward on the 1971-96 GM B-Body chassis, but builders should note that if the vehicle has been significantly lowered, modified or equipped with an aftermarket rear end housing, verification of bushing orientation, mount height and adjustment range is recommended. Properly tuned trailing arms like the QA1 5254 make a major difference in rear-end stability, traction and ride quality - particularly in high-performance or restored applications.
