Yukon Gear Grizzly Locker / Dana 50 / 30 Spline

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 that’s 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 Locker’s larger teeth also resist breakage caused by shock-loading or catastrophic axle failure. It’s a serious piece of mechanical engineering for serious driving conditions.This Part Fits: Year Make Model Submodel 2003-2005 Ford Excursion Eddie Bauer 2000-2005 Ford Excursion Limited 2004-2005 Ford Excursion XLS 2000-2005 Ford Excursion XLT 1983-1986,1997-1999 Ford F-250 Base 1980-1982,1987-1992 Ford F-250 Custom 1995-1996 Ford F-250 Eddie Bauer 1997-1999 Ford F-250 Lariat 1980-1981 Ford F-250 Ranger 1980-1981 Ford F-250 Ranger Lariat 1980-1981 Ford F-250 Ranger XLT 1995-1996 Ford F-250 Special 1982-1999 Ford F-250 XL 1982-1983 Ford F-250 XLS 1983-1984,1993-1999 Ford F-250 XLT 1982,1985-1992 Ford F-250 XLT Lariat 1999-2002 Ford F-250 Super Duty Lariat 1999-2002 Ford F-250 Super Duty XL 1999-2002 Ford F-250 Super Duty XLT 1983-1986 Ford F-350 Base 1980-1982 Ford F-350 Custom 1980-1981 Ford F-350 Ranger 1980-1981 Ford F-350 Ranger Lariat 1980-1981 Ford F-350 Ranger XLT 1982-1986 Ford F-350 XL 1982-1983 Ford F-350 XLS 1983-1984 Ford F-350 XLT 1982,1985-1986 Ford F-350 XLT Lariat 1999-2002 Ford F-350 Super Duty Lariat 1999-2002 Ford F-350 Super Duty XL 1999-2002 Ford F-350 Super Duty XLT
