Stage 1 Chassis Kit UE13510T
Optional Ti Center Drives Chassis Assembled
Our nitro chassis utilizes a lattice and truss style construction where the force flow has been extensively analyzed and any extra material has been removed. We’ve designed it to withstand a simulated impact of 2500 lbs. The deck and lower braces are super thick yet in racing configuration is significantly lighter than stock. This chassis has been optimized for the .21 engines. It’s not just another extended chassis. The chassis and lower brace system interlocks, forming a very rigid structure. No longer does you transmission hold your truck together.

The throttle servo’s position have been optimized for slide carbs and for superior brake control. There’s no possibility of getting brakes under full throttle (a common problem with the stock setup)

You may use all the stock components, or optional fuel tank, 5 cell hump packs, racing configurations, and more.

No special headers or pipes are required, there’s lots of room to mount any combination you like. We recommend RB’s or Ofna’s one-piece pipe (not really one piece but a sealed coupler), a beautiful polished aluminum pipe that works and performs great. The RB is a little more compact and performs better, though is more expensive. Some gearing limitations may exist depending on motor, pullstart size, stock or aftermarket tank etc.
