UMI Performance 403133 - 1964-1972 GM A-Body Tubular Upper & Lower Front A-Arm Kit

Upgrade your classic A-Body and enhance its performance with a set of fabricated tubular a-arms from UMI Performance. The P/N 403133 upper and lower a-arm kit replaces stock stamped a-arms with high-strength tubular construction for improved strength and durability. The lower a-arms feature tough tubular construction with polyurethane spring isolators and greaseable polyurethane bushings for smooth suspension motion and precise handling. The upper a-arms come with UMI-designed Delrin bushings and billet chromoly cross shafts for low deflection and increased caster angle. Both a-arms are TIG welded for superior strength and a clean look. The kit is designed to work with factory springs, lowering springs, and coil over kits, and includes recommended alignment specs and detailed installation instructions. The hardware kit, Part # 4004, includes Grade 8 bolts, washers, and zinc plated nylock nuts for a complete installation. The a-arms come in a durable red or black powder coat finish and are proudly made in the USA. Please note that the upper a-arm is not recommended for use with cargo coils or above stock height cars, as the bump stop may contact the cross brace.
