Detroit Locker for Ford 8.8" with 31 spline axles

The Detroit locker provides maximum traction for off-road or racing use. The heavy-duty case and internals provide a dramatic increase in strength while giving 100% torque to both tires. The mechanically-operated unit works by locking while under power and unlocking when you let off the gas, allowing you to turn. Unit comes standard with a one year warranty against workmanship defects. In applications with 4.88 or higher ratios, the ring gear will need to be ground to clear the c/clip block.
