O.S. Engines .18 TM Engine

More muscle for your Traxxas^® truck!

The 18TM is the hassle-free way to pump up the performance in your T-Maxx or Revo monster machine... because you don't have to modify your model to make it fit! Just drop it in — and you'll instantly enjoy more race-winning speed, as well as more power for backyard bashing!

Lighter and smaller than any .21-size engine, yet the 18TM outperforms them where it counts — on the track and on tough terrain.

The oversized head is a new 2-piece design that simplifies maintenance.

Traxxas' clutch assembly bolts right on the 18TM with no modification required.

OSMG2112 includes: One O.S. Max 18TM Engine with Revo Manifold, LC3 glow plug, 11K slide valve carburetor, manifold spring, rubber exhaust gasket, sticker sheet and instruction manual.

OSMG2115 includes: One O.S. Max 18TM Engine with T-Maxx Manifold, LC3 glow plug, 11K slide valve carburetor, manifold spring, rubber exhaust gasket, sticker sheet and instruction manual.

The manifold on the 18TM is a direct fit into the T-Maxx; it also adapts perfectly to Traxxas E-Z Start™ Electric Starting System or pull-start systems with no modifications.

Fins on the 3-needle, slide-valve 11K carb work to cool fuel temperature. The idle screw is positioned down inside to prevent breaking off during rugged off-road action.

Oversize fins on the newly designed crankcase help to keep the engine cooler.
