Add Adjustment To Your A-Arms
Is it time to add some adjustment to your 1979-1993 Fox Body Mustang A-Arms? UPR's 1979-1993 Chrome Moly Adjustable Tubular A Arms are 1" shorter, and are fully tig welded. They are the bulletproof fix for drag Mustangs that suffer from the decreased performance from aftermarket brakes. The adjustable A-Arms were created for drag racing Mustangs running large aftermarket brakes; causing the wheels to push out. They will come with a high-gloss Silver powder coat finish for an awesome look on your Fox Body Mustang! UPR's tubular A-Arms also come with high-quality ball joints with zerk fittings for easy maintenance.

A-Arm Strength
The UPR adjustable A-Arms feature a unique 1" x .095 wall design. This gives you more strength, saves weight (save up to 16 lbs over a factory A-Arm) and increased performance. They are made from CNC tubular Chrome-Moly steel and tig welded for longevity.

About This Brand

In 1989, Mark Mainiero and his son Joe started UPR Products with Mustangs in mind. With the help of their employees Jeremy Martorella and Bart Tobener, they brought in more racing victories and records than any other shop of that time. In 1998, Joe recognized the need for a company that fully understood the Mustang racer's suspension needs. While making customer service his main priority, he strived to offer the strongest, lightest, and highest quality parts at an affordable price. A firm believer in the “keep it simple” philosophy Joe made sure all his components could be easily installed and adjusted. Shop UPR for high quality Mustang performance and dress up components.
