Yukon Gear Grizzly Locker For Model 35 w/ 30 Spline Axles / 3.54 Up

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. The Yukon Grizzly Locker is the ultimate in mechanical locking differentials for street; off-road; and drag racing. Grizzly Lockers provide 100% power to both tires; while still allowing for disengagement while negotiating turns. This unit is double drilled for both 3/8" & 7/16" ring gear bolts and uses carrier bearing & race part numbers LM102949 & LM102911.

• Patented internal design reduces common locker failures
• Fits AMC Model 35 with 30 spline axles
• Fits AMC Model 35 w/30 Spline Axles
• 8620 internals for added strength
• 3.56 and up ratio only
• Assembled in the USA

The Yukon Gear & Axle Grizzly Locker, part number YGLM35-4-30, is a mechanical positive-locking differential designed for demanding street, off-road, rock-crawling, trail-running, off-road racing, and drag-racing applications. Built for AMC Model 35 differentials with 30-spline axles, this locker delivers full engine power to both tires for maximum traction while allowing the differential to disengage during turns. It is intended for vehicles using 3.56-and-up gear ratios and provides dependable performance in conditions where conventional limited-slip differentials may not be sufficient.
The patented Grizzly Locker design incorporates larger internal clutch teeth with a generous radius at the base to resist breakage from shock loading and severe axle failures. Compared with back-cut designs, this geometry provides up to 350% greater strength at the tooth base. The Yukon Grizzly Locker also uses robust 8620 steel internals for added durability in high-impact driving environments. Its mechanical operation requires no air lines, electrical controls, or external actuation, making it a direct and reliable traction solution for serious performance vehicles.
This Yukon Gear & Axle locker is double drilled to accommodate both 3/8-inch and 7/16-inch ring gear bolts. It uses carrier bearing and race part numbers LM102949 and LM102911. The unit is assembled in the USA and is engineered to provide positive traction with controlled disengagement during cornering. Verify axle spline count, differential model, ring gear bolt size, and gear ratio before installation to ensure proper fitment. Listed applications include select Jeep Cherokee models, including 1990, 1989, 1997, 1995, and 1994 vehicles.
