This product is a set of anodized green aluminum 30° caster blocks designed to position the front suspension and steering knuckles at the correct steering angle for improved handling performance. The aluminum construction offers greater strength and durability compared to stock composite caster blocks, helping reduce flex and wear under high‑stress off‑road driving. Precision machining ensures proper fit and alignment with suspension and steering components for consistent steering response. RC car compatibility includes Traxxas 1/10‑scale models that use 30° caster blocks—such as Slash, Rustler, and similar vehicles—and it serves as a direct replacement or upgrade to restore precise front suspension geometry and enhanced durability.
