Traxxas 9733‑ORNG caster blocks are durable upgrade components designed to enhance steering precision and suspension stability on your RC crawler. Made from solid orange‑anodized brass, these caster blocks add weight low on the chassis to improve traction, cornering control, and anti‑roll performance on uneven terrain. The brass construction also offers greater resistance to wear and bending compared to standard composite parts while giving your crawler a rugged, scale‑accurate look. These caster blocks install easily using standard suspension hardware for a secure fit.
