21TM Engines

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!
