21TM ABC .21 Engine for Traxxas Revo (OSMG2082)

OS 21TM ABC .21 engine for Traxxas Revo RC trucks is a high-performance upgrade designed to boost power and displacement without requiring any chassis modification. It’s a direct-fit replacement that works with Traxxas EZ-Start or pull-start systems and includes the manifold and clutch assembly for simple installation.

Compared with the 18TM, the 21TM delivers more power and displacement while using the same mounting pattern, so the Traxxas clutch bolts on easily. The included manifold adapts to existing pull-start or EZ-Start configurations, and the engine features a 3-needle carburetor and LC3 glow plug for precise tuning and reliable starts. Lightweight and easy to operate, this upgrade is designed to fit Revo models in 2.5 and 3.3 configurations.
