A-Arm Spacer 1/8in 6in Bolt Center

The JOES Racing Products A-Arm Spacer 1/8in 6in Bolt Center (Part #14020) is a precision aluminum control arm shim engineered for suspension geometry adjustment on race-tuned and competition vehicles. Manufactured from natural aluminum to exacting tolerances, this 1/8-inch spacer interfaces with control arm assemblies using 6-inch bolt center spacing—a configuration common across high-performance chassis setups where adjustable geometry is critical to handling consistency.

The 1/8-inch thickness allows incremental camber and caster correction without requiring full control arm replacement or complex shimming stacks. At 0.06 pounds and compact dimensions (3 x 0.3 x 9.65 inches), this spacer mounts cleanly within tight suspension bays typical of race cars, off-road buggies, and track-focused street machines. JOES Racing's aluminum construction provides lightweight performance while maintaining structural rigidity under cornering loads. The shim's standardized 6-inch center spacing ensures compatibility with OEM and aftermarket control arm designs spec'd to that bolt pattern, making it a direct-fit upgrade for suspension tuning without frame modification.

This spacer is essential for builders and suspension technicians dialing in front-end geometry on circle-track cars, road racing platforms, or performance street vehicles. Fine-tuning camber angle improves tire contact patch consistency, reduces uneven wear, and sharpens turn-in response—outcomes that matter when lap times or handling precision are non-negotiable. Sold individually, this single spacer can be used as part of a larger shimming strategy or integrated into a new suspension build where geometry correction is engineered into the setup from the outset.
