Traxxas 10733‑RED 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 red finish not only adds corrosion resistance but also gives your vehicle a custom look. 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 models equipped with front steering suspension systems that use caster blocks.
