    Manufacturer's Part Number:

    With the available upgraded 9310 mainshaft, these synchronized gear kits will handle roughly 600 hp or 500 ft-lb. of torque in a 3300 lb. vehicle with drag radials and moderate clutch upgrade. Available with the preferred 2.94, 1.94, 1.34, 1.00 ratios in gears 1 thru 4 or the 2.42, 1.53, 1.23, 1.00 and utilizes a stock .59 overdrive which allows the engine to turn less RPM at cruising speed for less engine wear and better gas mileage while still maintaining incredible acceleration in the first 4 gears. All gear kits must be installed in World Class transmissions only.
