The Patent Pending TORQ Locker is the newest locking differential by Torq-Masters Industries. This new line will feature 1-ton and larger axle offerings. The robust design eliminates the pins found in other automatic locking differentials by using a key-way design. The ratcheting process is aided by 2 heavy duty stainless steel springs. With this design we have eliminated the spacers found in other automatic locking differentials to make the install much easier and quicker. We are proud to say that the TORQ Locker is 100% Made in the U.S.A. with only US raw materials.
