Traxxas 10733‑GRN aluminum caster blocks are high‑strength upgrade components designed to enhance durability and steering precision on your RC crawler. These precision‑machined aluminum blocks provide increased rigidity and resistance to wear compared to standard composite parts, helping maintain proper front suspension geometry and improve handling on rough terrain and technical trails. The anodized green finish adds corrosion resistance and a custom look that stands out on the trail. These caster blocks install easily using factory hardware for a secure, precise fit, and they are compatible with Traxxas TRX‑4 and TRX‑4 M scale crawler models that use caster blocks in their front suspension.
