Spacer Kit Upper A-Arm

The QUICKCAR Racing Products Spacer Kit Upper A-Arm (part number 56-124) is a precision control arm shim kit engineered for suspension geometry tuning on race vehicles and high-performance platforms. This aluminum spacer kit enables fine adjustments to upper A-arm positioning, critical for dialing in caster, camber, and roll center geometry on track or off-road applications where suspension precision directly impacts handling balance and tire wear patterns.

The kit features aluminum construction with 6-inch center spacing, accommodating adjustment ranges from 1/16 inch to 1/2 inch. This range allows technicians to make incremental geometry corrections without requiring complete suspension redesign. The modular spacer approach is standard in motorsports suspension tuning, where small adjustments to A-arm angle translate to measurable changes in vehicle dynamics. Weighing 0.64 lbs, the kit remains lightweight while maintaining structural integrity required for sustained track or competition use.

This spacer kit is essential for suspension builders, race engineers, and dedicated motorsports enthusiasts performing geometry optimization on circle track, drag racing, road course, or off-road competition vehicles. It's suited for applications requiring repeatable adjustment capability without permanent modification to factory suspension components. The aluminum material resists corrosion while maintaining the lightweight profile demanded in racing platforms.

Compatible with QUICKCAR Racing Products suspension systems and standard A-arm mounting configurations with 6-inch center spacing, this kit supports the incremental tuning workflow essential to competitive motorsports development.
