UMI Performance 2317-B Drag Race Lower A-Arm Set | 1993-2002 GM F-Body CrMo

UMI Performance's 2317-B drag-specific lower A-arm set is engineered for 1993–2002 GM F-Body platforms, delivering a direct bolt-in replacement that sheds weight without sacrificing structural integrity. Saving 5 lbs per side (10 lbs total), these arms are built from chromoly (CrMo) steel tubing with a newly redesigned tube configuration for maximum performance and safety under extreme drag racing conditions.

Each arm ships fully assembled with a factory-installed ball joint seated in a heavy-duty double-reinforced ball joint cup, and race-quality rod ends — including a high-misalignment rod end on the rear strut mount — so they are ready to install right out of the box. The arms maintain the factory track width and accept most major brands of racing coilovers via the industry-standard ½" shock mount (up to 1-¼" wide).
