What is the main benefit of using adjustable lower control arms?

Adjustable lower control arms allow you to fine-tune your rear suspension geometry. This helps minimize wheel hop, improve cornering stability, and achieve a more consistent track alignment for better performance.

Are these control arms noisy on the street?

No, the kit uses Energy Suspension fluted polyurethane bushings and QA1 rod ends with Teflon/Kevlar linings. These components are designed to provide quiet operation and a comfortable ride, even with the improved performance they offer.

Do I need any special tools or hardware for installation?

Installation is designed to be a simple bolt-on process using your vehicle's original hardware. No drilling is required, and the kit includes grease fittings for easy maintenance of the bushings.

Ford Mustang 1979-1998

Product Details

UMI Performance is well-known for making solid suspension components for American muscle cars. If you're working on a 1979-1998 Ford Mustang and want to dial in your rear suspension, this kit with adjustable lower and fixed upper control arms is a great way to go. These parts are designed to replace your stock control arms, helping to reduce wheel hop, improve how the car handles in corners, and make your track or autocross runs more consistent.

The lower control arms are built from strong 0.120-inch wall DOM mild steel tubing and feature a 4130 chrome-moly threaded adapter. They use QA1 three-quarter inch rod ends with a Teflon/Kevlar lining for smooth, quiet operation and easy adjustment, which is crucial for fine-tuning your alignment. The polyurethane bushings, paired with CNC-machined aluminum step bushings and zinc-plated steel sleeves, help keep road noise down while still providing a firm connection to the chassis. You'll also find reinforced spring perches and sway bar mounting points on the lower arms. The upper control arms are also well-built with steel tubing and polyurethane bushings, completing the set for a balanced upgrade.

Installation is straightforward as these are direct bolt-on replacements that use your factory hardware, so no drilling is needed. The durable powder coat finish helps protect them, and the grease fittings on the bushings make maintenance simple. This kit is a solid option for anyone looking to get more out of their Mustang's rear suspension.
