The Traxxas 5170 recoil starter is a pull‑start assembly designed to provide reliable and easy engine starting for nitro‑powered RC vehicles, featuring a durable recoil mechanism and grip that lets you quickly spin the engine over without the need for an electric starter box. Built to withstand repeated use, this starter helps get your nitro engine running smoothly and is a direct replacement for worn or broken starter units. The Traxxas 5170 recoil starter is compatible with nitro‑powered Traxxas trucks and buggies that use a recoil start system, such as the Nitro Rustler, Nitro Slash, T‑Maxx 3.3, Revo 3.3, Slayer Pro 4×4, and similar TRX engine models.
