Everything about the Yukon Grizzly Locker is hardcore, its casing and gears, its advanced gear tooth design, and its impact on traction and performance. The Yukon Grizzly Locker is a mechanical positive-locking differential thats engineered for rock crawling, serious trail running, off-road racing, and drag racing. The unit provides 100% power to both tires, while still allowing for disengagement while negotiating turns. The Yukon Grizzly Locker is a patented design that features innovations that make it tougher than the competition. Its inner clutch teeth have a larger radius at the base, which offers up to 350% greater strength versus back-cut designs. The Grizzly Lockers larger teeth also resist breakage caused by shock-loading or catastrophic axle failure. Its a serious piece of mechanical engineering for serious driving situations.Additional Attributes:GTIN:00883584280262Material:SteelCover Bolt Quantity:12Axle Shaft Spline Quantity:35California Proposition 65:NoType:LockingExtended Information:Emissions :CARB EligibleLife Cycle Status:Available To OrderPackaging:Quantity of Each:1.0Package UOM:EADimension:11.0000 x 10.0000 x 11.0000 inchesWeight:36.3200 PG
