Locking differentials replace your differential carrier and are sometimes called lockers or lockable differentials. They lock the axles together, providing 100% of available torque to both wheels, regardless of whether one is off the ground or on a low traction surface. When the vehicle turns, a locking differential functions like an open differential, allowing the wheels to rotate at different speeds. To learn more about differentials, check out this video on our official blog, On All Cylinders.

Locking differentials replace your differential carrier and are sometimes called lockers or lockable differentials. They lock the axles together, providing 100% of available torque to both wheels, regardless of whether one is off the ground or on a low traction surface. When the vehicle turns, a locking differential functions like an open differential, allowing the wheels to rotate at different speeds. To learn more about differentials, check out this video on our official blog, On All Cylinders.
A ratcheting sound can be heard around corners as the clutch and spider assembly disengage and is normal. When traction is needed under load, the axles mechanically lock together, forcing the wheels to rotate at the same speed, similar to a spool.
Many Jeep owners install a Dana 30 locker or a Dana 44 locker front and rear locking differential to enhance off-roading capabilities. When the differential is locked, the wheel off the ground doesn't receive any torque due to lack of traction, while the wheel on the ground gets all the torque, enabling the vehicle to move effectively.
Summit Racing carries a large selection of both front- and rear-axle differentials from top-name manufacturers, including Eaton, Detroit Locker, Auburn Gear, ARB, Yukon Gear & Axle, Powertrax and many more.
