The Traxxas 5364X Brake Disc is a high‑performance 40 mm vented steel brake disc engineered to improve braking performance and heat dissipation compared to standard brake discs, helping your RC vehicle stop more consistently during intense runs. Its vented design allows heat to escape more efficiently, reducing the risk of brake fade under heavy braking conditions and delivering smoother, more controlled deceleration. This brake disc is a durable replacement or upgrade part that fits in the brake assembly of nitro‑powered Traxxas trucks and is compatible with models such as Traxxas Revo 3.3, Traxxas Slayer Pro 4×4, and Traxxas T‑Maxx 3.3, and other vehicles that use the 40 mm vented disc setup.
