Traxxas 5035 60W shock oil is a high‑viscosity silicone damping fluid used in the shock absorbers of compatible Traxxas RC vehicles to provide strong resistance to compression and rebound, helping deliver firmer suspension control, reduced bottoming on big jumps, and more predictable handling on rough terrain; it’s ideal for shock tuning or replacing old fluid when you want a stiffer, more performance‑oriented ride.
