Description

Precise caster adjustment is critical for dialing in your suspension geometry, and this A-Arm slug delivers the repeatability you need for consistent lap times. The 7/16-inch offset allows fine-tuned caster changes without requiring complete upper control arm replacement, saving you time and money in setup refinement. Built from aluminum and black anodized for durability, it’s a straightforward bolt-on solution for Joe’s slotted upper control arms.
