Yukon Grizzly Locker is an automatic, speed sensing locker. It will lock up when there is a wheel speed difference side-to-side. They are fitted with internal components that allow for differentiation in turns. Automatic lockers are very popular in the four-wheeling world and are known for allowing the driver to concentrate on other elements of driving by letting the locker figure out when to engage. Automatic lockers are also used on performance cars, most commonly for acceleration.
Mechanical positive-locking differentials have been the staple for drag racing, circle track racing, off-road use and a variety of other performance applications for decades. The Grizzly Locker is the latest in locking differentials. This locker features an 8620 case, forged with 8620 internals and a patented design which reduces common locker failures. The inner clutch teeth have an improved design, with a larger radius at the base, improving strength over back-cut designs. Larger teeth help to avoid breakage against shock-loading or in the event an axle breaks. The internals are hand fittted, for faster engagement. These units provide maximum traction and strength for many performance applications. Grizzly Lockers are available for a variety of car and truck applications, with new applications being added all the time! What's also great? It's assembled in the USA!
When you purchase a Grizzly Locker, we recommend purchasing the carrier installation kit, which includes new carrier bearings and shims. Replacing these components when you install the Grizzly Locker will insure optimal performance of the locker and make the installation easier. An alternative to the carrier kit is the complete Differential Installation Kit, which will also include all of the bearings and seals in the differential.
