Manuals & SupportA performance boost for one of R/C's most popular trucks!
Boost the 4WD performance power in your Traxxas® Revo® with the 21TM engine from O.S.! It's the perfect upgrade for your monster masher — because it's a direct fit for Traxxas EZ-Start® or pull-start systems, as is the manifold and clutch assembly!

- The 21TM adds more power and displacement than the 18TM – and without modification!
- Retrofits into the same mounting pattern, and the Traxxas clutch assembly bolts right on.
- The special manifolds adapt perfectly to existing pull-start or EZ-Start® systems.
- Reliable, lightweight and easy to operate – and both include a 3-needle carb for more precise tuning and an LC3 glow plug.
