A-Arm Slug Slotted

The JOES Racing Products A-Arm Slug Slotted (Part No. 15051) is a precision aluminum control arm caster slug engineered for high-performance suspension tuning and adjustable geometry applications. This black anodized component features a slotted design with a 1/2-inch ID hole, allowing fine-adjustment capability essential for race teams and suspension specialists who need to dial in caster angles with precision during setup and on-track refinement.

Constructed from durable aluminum with black anodized finish, the slug resists corrosion while maintaining minimal weight at just 0.02 lbs—critical in motorsport applications where every fraction of a pound affects handling balance and acceleration. The slotted configuration permits micro-adjustments to caster settings without complete disassembly, a feature that separates serious suspension work from basic bolt-on modifications. The 1/2-inch hole diameter is standard for JOES Racing upper control arm systems, ensuring compatibility across their proven lineup.

This slug serves racers, suspension technicians, and off-road vehicle builders who demand adjustable geometry for competitive advantage. Whether tuning a road race platform, drag car, or off-road racing setup, the ability to adjust caster geometry on-site—without fabrication delays—translates directly to faster track times and better vehicle handling across varying conditions. JOES Racing's reputation in the high-performance community is built on components like this: straightforward engineering that enables real suspension adjustments.
