UMI Performance 79-04 Ford Mustang Adjustable Upper Control Arms - Ultimate Arms

When you're looking to fine-tune the rear suspension on your 1979-2004 Ford Mustang, especially for performance driving or after installing a new rear end, adjustable upper control arms are a smart move. These UMI Performance Ultimate Arms allow you to dial in your pinion angle, which is crucial for proper driveshaft alignment, and also adjust the lateral location of the rear axle. Getting these settings just right can make a notable difference in how your Mustang handles and how smoothly the power gets to the ground.

What sets these apart is the combination of strength and adjustability. UMI uses laser-cut mild steel brackets and CrMo adjusters, all TIG welded for solid construction. The arms feature race-quality, Teflon-lined rod ends that offer precise movement and durability. This means they're built to handle the stresses of spirited driving and can be adjusted right on the car, making the tuning process much more straightforward. The durable powder coat finish helps protect them from the elements.

Installation is designed to be a bolt-in process, typically taking about an hour once you have the car on stands. You will reuse your existing outer metal shells for the differential bushings, but new grade 10.9 mounting hardware, including 12mm bolts and Ny-lock nuts, is included to make the job easier. These arms are crafted with pride in the USA.
