The GrudgeBox is a tough overdrive 6-speed to replace your stock 6-speed!
The GrudgeBox was engineered with a focus on excessive torque capacity and crisp shifting. All gears are straight cut in a way that ensures maximum power transfer to the rear wheel. This gearset was designed and geared for the everyday highway riders, speed freaks, and even racers!
Key Features:
- Built to take high horsepower abuse found in late model H-D performance applications while providing elegant shift precision.
- All gears are straight cut for negligible parasitic power loss, providing maximum power transfer to the rear wheel
- Wide-ratio gearing for heavier performance applications
- Built for aggressive take-offs and long distances at above-average speeds
- 250 RPM drop at higher highway speeds (approx. 80 mph)
- Engineering focus on excessive durability
- Gears up to 40% wider than stock
- Positive dog tooth engagement in gear with pie-shaped shift dogs
- Frictionless linear detent shift system for smooth shifting
- Redundant neutral detent to make it easy to find neutral
- Low effort, single-axis/linear motion ratchet pawl for crisp, tight and easy shifting
- More durable than stock
- Typically no clearance is required- the gearset is designed to fit in an OEM case. On occasion, the case may require clearance due to OEM fluctuations in the case casting process.
