Description

Part #: SPL RUA S550

S550 Mustang Rear Upper Arms (RUA) were carefully designed to provide strength, clearance to axle and frame, while allowing for huge range of adjustment. The rear upper arm eliminates the need to adjust from the far inboard side of the arm, which is incredibly hard to reach, and moves all adjustment to the knuckle side, easing alignments. The inner bolt is locked out to a single position, so all adjustments will be done using our double adjustment mechanism, making fine-tuning the rear camber far easier. The assembly uses a 6061-T6 Billet Aluminum body, hardened SPL Double Adjuster specifically designed for the application, as well as hardened rod ends, making this part exceptionally strong to be able to hold any and all loads that are put through it by the stickiest tires you can put on your Mustang. The arm was designed with FEA to ensure it could hold the loads, then destructively tested to confirm the FEA. All the wear components (rod ends) are easily replaceable in this assembly.
