About this part

Product Details

These upper adjustable trailing arms from QA1 are built with graphite/polyurethane bushings, offering a solid upgrade for your 1978-1988 GM G-body or 1973-1977 A-body vehicle. They are designed to allow for easy adjustment of your vehicle's wheelbase and pinion angle, which is crucial for getting your suspension dialed in after modifications or for fine-tuning handling characteristics.

Installation is straightforward, as these arms are made to be a direct, bolt-in replacement for your stock components, meaning no welding or cutting is required. The combination of graphite and polyurethane in the bushings helps to provide a good balance between road feel and vibration dampening, while also being durable for regular use. QA1 is known for making well-built suspension components, and these trailing arms are no exception, offering a practical way to improve your vehicle's rear suspension setup.

This set is designed to fit a wide range of popular GM vehicles, including models like the Chevrolet Monte Carlo, Buick Regal, and Oldsmobile Cutlass Supreme. Having adjustable trailing arms can make a notable difference in how your car launches and handles, especially if you're working with a lowered vehicle or making performance-oriented changes.
