    Baker Drivetrain Wrinkle Black Standard Shift 6 Speed GrudgeBox Builder's Kit

    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!

    • 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 with 40% wider gears than stock.
    • 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
    • The GrudgeBox has different gear ratios than the stock transmission (except GrudgeBox 5th gear is the same as stock 6th gear, 1:1). This changes the input to the ECM. The 42-tooth reluctor ring in the GrudgeBox compensates to correct the speedometer within ± 2 mph with no re-flash to the ECM. However, the gear indicator and cruise control may only operate in 5th gear. To correct the gear indicator in all gears and enable cruise control in 3rd, 4th, and 6th, an ECM re-flash is required. Existing tuners must have an option to modify transmission gear ratios in order to re-flash the ECM
    • Hand built and made in the U.S.A.
