21TM Engine with Revo® or T-Maxx® Manifold 21TM Engine with Revo® or T-Maxx® Manifold

More monster muscle – for racing or bashing!

  • 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-StartTM systems.
  • Reliable, lightweight and easy to operate – and both include a 3-needle carb for more precise tuning and an LC3 glow plug.
