Yukon Gear Grizzly Locker For Ford 8in w/ 31 Spline Axles

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 1969-1974 Ford E-100 Econoline Base 1969-1974 Ford E-100 Econoline Club Wagon 1957-1970 Ford Fairlane 500 1966-1967 Ford Fairlane 500XL 1957-1969 Ford Fairlane Base 1978 Ford Fairmont Base 1978 Ford Fairmont Futura 1960-1961,1963-1970 Ford Falcon Base 1962 Ford Falcon Deluxe 1964-1970 Ford Falcon Futura 1964-1965 Ford Falcon Futura Sprint 1961-1965 Ford Falcon Sedan Delivery Base 1972-1976 Ford Gran Torino Base 1973-1976 Ford Gran Torino Brougham 1974-1975 Ford Gran Torino Elite 1972-1975 Ford Gran Torino Sport 1972-1976 Ford Gran Torino Squire 1975-1979 Ford Granada Base 1978-1979 Ford Granada ESS 1975-1979 Ford Granada Ghia 1965-1978 Ford LTD Base 1970-1976 Ford LTD Brougham 1975-1978 Ford LTD Country Squire 1975-1978 Ford LTD Landau 1970-1977 Ford Maverick Base 1975-1977 Ford Maverick Grabber 1964-1973,1979 Ford Mustang Base 1969-1971 Ford Mustang Boss 302 1971-1972 Ford Mustang Boss 351 1969-1970 Ford Mustang Boss 429 1979 Ford Mustang Ghia 1970-1973 Ford Mustang Grande 1970-1973 Ford Mustang Mach 1 1965-1970 Ford Mustang Shelby GT-350 1966 Ford Mustang Shelby GT-350H 1967-1970 Ford Mustang Shelby GT-500 1968 Ford Mustang Shelby GT-500KR 1971-1980 Ford Pinto Base 1976-1980 Ford Pinto Pony 1976-1980 Ford Pinto Squire 1967-1979 Ford Ranchero 500 1967 Ford Ranchero 500 XL 1964-1971 Ford Ranchero Base 1966 Ford Ranchero Custom 1968-1979 Ford Ranchero GT 1970-1979 Ford Ranchero Squire 1963-1964 Ford Sprint Base 2005 Ford Thunderbird 50th Anniversary Edition 2002-2005 Ford Thunderbird Base 2004 Ford Thunderbird Pacific Coast Roadster 1971 Ford Torino 500 1968-1976 Ford Torino Base 1970-1971 Ford Torino Brougham 1969,1971 Ford Torino Cobra 1968-1969,1971 Ford Torino GT 1969-1971 Ford Torino Squire 1971 Ford Torino Super Cobra Jet 1975,1977-1980 Mercury Bobcat Base 1976 Mercury Bobcat MPG Runabout 1976-1980 Mercury Bobcat Runabout 1976 Mercury Bobcat S Runabout 1976-1980 Mercury Bobcat Villager 1969-1977 Mercury Capri Base 1964-1965 Mercury Comet 202 1964-1965 Mercury Comet 404 1962-1969,1971-1977 Mercury Comet Base 1962-1963 Mercury Comet Custom 1962-1963 Mercury Comet S-22 1967-1970 Mercury Cougar Base 1969-1970 Mercury Cougar Boss 302 1969-1970 Mercury Cougar Boss 429 1969-1970 Mercury Cougar Cobra Jet 1967-1970 Mercury Cougar XR-7 1978 Mercury Zephyr Base 1978 Mercury Zephyr Z7
