Big block power
The 4.6 big block engine is extremely powerful. With a super-size heat-sink you will never have issues with high temperatures and overheating. A high-flow dual stage air filter protects the engine from contamination. Tuning and adjustments are simple and you can have the BR50 up and performing in a short amount of time. The engine is equipped with a pull start system, so no need for an expensive starter box. The aluminum pipe is very lightweight and has been tuned to the engine for maximum power.

The BR50 chassis was designed for an ultra low center of gravity, to be lightweight and have maximum suspension travel. The result is a very easy handling chassis right out of the box and with all the options for setup you can fine tune it to your driving style and track conditions. Long oil-filled 14mm piston aluminum shocks with 3.5mm shafts and super strong composite suspension arms let the car fly over bumps and jumps. The heavy duty aluminum shock towers are strong and allow multiple shock positions for further tuning. All the suspension pins are supported in rubber bushings; this elastic connection avoids damage to the suspension during severe use. The BR50 has three low profile differentials all with 6 hardened metal gears. The aluminum-top deck is ultra low further adding to the low center of gravity. All this adds up to a strong performing chassis with performance advantages you can feel right out of the box.

Fully Adjustable
The BR50 offers a wide range of tuning adjustments so that you can fine tune your truck to any driving condition. All important suspension points are easily adjustable.

  • 36 possible shock positions available to fine tune your suspension.
  • Spring-clips for adjustment of ride height.
  • Adjustable front and rear camber
  • Adjustable steering geometry.
  • Front inboard toe angle adjustments: 0º to -2 º
  • Rear inboard toe angle adjustments: 0º to -2 º
  • Front kick up angle adjustments: 0º to 2 º
  • Rear anti dive angle adjustments: 0º to 2 º

The BR50 has been designed for easy access to all important components of the car. All 3 differentials are within easy reach; if you need to access them simply remove 4 screws. The engine and pipe assembly can be pulled out by removing 4 screws. Reaching the steering and suspension adjustment points require removal of only a couple screws each.
