Better Performance. The 2011-2014 Mustang's stock stamped steel upper control arm is notorious for deflecting during cornering and hard launches which results inconsistent handling due to excessive flex. The heavy duty construction of BMR's Adjustable Rear Upper Control Arm will give you remarkably improved handling and consistent performance by reducing deflection and eliminating control arm flex. High compression launch and acceleration loads are handled easily by the polyurethane bushings and its adjustable design offers an easy way to fine tune the pinion angle of your 2011-2014 Mustang. Enjoy harder launches, reduced wheel hop and increased cornering performance with this red powder coated Rear Upper Control Arm.Quality Construction. Crafted from MIG-welded 1-5/8" 0.120 inch wall DOM steel tubing, this BMR Rear Upper Control Arm features on-car adjustability for ease of use and customization on the fly. The greasable 95-durometer polyurethane bushings are internally fluted to retain the added grease within the bushing. With a CNC-machined chrome-moly center adjuster and TIG-welded chrome-moly tube adapters, this Upper Control Arm offers ultimate durability and strength. Proudly designed and made in the USA, it's completed in a vibrant red powder coated finish.Recommended Upgrade. It's highly recommended to upgrade your stock upper control arm mounting bracket to a BMR Rear Upper Control Arm Mount when installing a BMR Adjustable Rear Upper Control Arm on an S197 Mustang. Failure to do so may result in a loud clunking noise without the upgraded mount installed. Application. The Red BMR Adjustable Rear Upper Control Arm with Polyurethane Bushings is designed for all 2011-2014 Mustangs including the V6, GT, Bullitt, BOSS, and Shelby GT500 models.
