64-72 GM A-Body Tubular Up & Low Front A-Arm Kit

The UMI PERFORMANCE 64-72 GM A-Body Tubular Up & Low Front A-Arm Kit is a complete front suspension control arm assembly engineered for classic Chevrolet A-Body muscle cars and street machines. This tubular-construction kit replaces OEM cast iron control arms with high-strength steel tubing, delivering improved geometry, reduced unsprung weight, and superior handling characteristics for both street and strip applications. The kit includes both upper and lower tubular arms with polyurethane bushings pre-installed, complete hardware, and black powder coat finish for corrosion resistance.

Tubular A-arms offer measurable advantages over factory cast designs: the rigid steel tube construction reduces deflection under cornering loads, while the lighter weight compared to cast iron improves acceleration and reduces the unsprung mass that affects ride quality. The polyurethane bushings provide a middle ground between sloppy rubber and harsh solid mounts—they resist deflection and last significantly longer than stock rubber in high-heat driving conditions, yet don't transmit excessive vibration. UMI's design maintains factory mounting points and integrates with coil-over suspension systems, making this kit compatible with modern damper upgrades common in restomod builds.

This kit suits owners rebuilding 1964–1972 Chevrolet A-Body chassis (Chevelle, Malibu, El Camino, and similar models) who want measurable suspension improvements without full frame modification. Street drivers benefit from sharper turn-in response and reduced body roll; competitors running road course events or autocross gain from the geometry precision and consistent handling this platform enables. The black powder coat finish resists surface corrosion in storage and outdoor use, though touch-up paint and periodic maintenance remain standard practice for long-term preservation.

Restoration shops and performance builders specify tubular front A-arm kits as a core suspension upgrade because they preserve the classic look while modernizing performance geometry. The kit weighs 50.2 lbs and ships in compact dimensions (16.5 x 16 x 20 inches), making logistics straightforward for shops managing multiple projects.
