O.S. 21TM Engines

O.S.® 21TM Engines

Features
  • 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.
A performance boost for two of R/C's most popular trucks!

Boost the 4WD performance power in your Traxxas® Revo® or T-Maxx™ with the 21TM engine from O.S.! It's the perfect upgrade for either monster masher — because both versions of the 21TM are a direct fit for Traxxas EZ-Start® or pull-start systems, as are the manifold and clutch assembly!
