one of R/C's most popular trucks!
Boost the 4WD
performance power in your Traxxas® T-Maxx™ 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.
