21TM ABC .21 Engine with Manifold for Traxxas T-Maxx (OSMG2083)

The O.S. 21TM ABC .21 Engine with Manifold for Traxxas T-Maxx is a high-performance powerplant designed to boost acceleration and top-end speed in Traxxas 4WD monster trucks. It delivers more displacement and power than the 18TM without modification and installs on the same mounting pattern with the Traxxas clutch assembly. The manifold is designed to work with EZ-Start or pull-start configurations, and the engine features a three-needle carburetor and LC3 glow plug for precise tuning and reliable starts.

Built for Traxxas T-Maxx models, including the 2.5 and 3.3 versions, this engine upgrade maintains easy installation while delivering stronger torque and faster acceleration. The retrofit preserves the familiar mounting pattern, and the lightweight design supports responsive performance, with the carburetor and glow plug enabling flexible tuning and dependable operation in demanding off-road use.
