UMI Performance 65-67 GM A-Body Rear Suspension Kit - Black

UMI Performance's kit includes tubular rear lower and upper control arms, new rear end housing bushings, and Grade 8 mounting hardware. Designed as a direct bolt-on replacement for A-Body vehicles, it reduces wheel hop, enhances cornering, and improves track consistency. Stock control arms often cause traction loss and poor handling due to weak materials and bushing deflection. Ideal for both weekend cruisers and track cars, the lower control arms feature grease-able bushings, TIG welded construction, and sway bar provisions reinforced with a 0.120" steel sleeve. Adjustable upper control arms allow pinion angle optimization for better performance. UMI’s A-Body rear kit includes tubular upper/lower arms, rear bushings, and Grade 8 hardware. Greaseable lowers with reinforced sway bar holes and adjustable uppers reduce wheel hop and improve handling.
