OS 12240 Max 21TM Engine w/11K Carb. & 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-Start™ systems.
• Reliable, lightweight and easy to operate – and both include a 3-needle carb for more precise tuning and an LC3 glow plug.
