63-87 C10 Upper Control Arm Kit

The 63-87 C10 Upper Control Arm Kit from QA1 is engineered for operators and enthusiasts maintaining or upgrading classic GM fullsize trucks from 1963 to 1987. Upper control arms are critical suspension components that establish wheel alignment geometry and control vertical wheel motion during braking, acceleration, and cornering. Whether you're restoring a vintage work truck or building a capable off-road platform, this tubular control arm pair addresses wear patterns common in aging suspensions while maintaining OEM-compatible geometry.

This kit features tubular steel construction with polyurethane bushings and a durable black powder coat finish designed to resist corrosion in demanding field conditions. Polyurethane bushings offer a balance between compliance and precision—they isolate vibration better than solid steel while providing tighter deflection control than worn rubber. The tubular design reduces unsprung weight compared to original equipment, improving suspension response and ride quality. QA1's manufacturing standards ensure consistent bushing preload and arm geometry, critical factors in preventing bump steer and maintaining tire wear patterns across the contact patch.

Technicians, restoration shops, and truck owners performing C10 suspension overhauls will find this pair essential for addressing alignment drift and restoring confidence in steering response. Installation requires frame-mount ball joint removal and proper alignment verification post-installation to maintain caster and camber specifications. Compatibility is exact for GM fullsize truck C10 platforms across the 1963–1987 model range. Weighing 19.14 lbs total and measuring 14.45 × 6.75 × 18.25 inches, the kit ships as a matched pair ready for immediate installation without machining or modification.
