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

The Yukon Gear & Axle YGLM35-4-30 Grizzly Locker is a high-performance mechanical positive-locking differential designed for serious off-road driving conditions, including rock crawling, trail running, off-road racing, and drag racing. This unit provides 100% power to both wheels while still allowing for disengagement during turns. Engineered for upgraded 30-spline Dana 35 rear axles, it is compatible with gear ratios of 3.54 and higher. The Grizzly Locker features a patented design with inner clutch teeth that have a larger radius at the base, offering up to 350% greater strength compared to back-cut designs. Its larger teeth also resist breakage from shock-loading or catastrophic axle failure. The internals are constructed from forged 8620 steel, housed within a chromium alloy steel casing that protects against corrosion and rust, ensuring better-than-OEM build quality. Professional installation is suggested due to the complexity of the installation process, which requires an axle upgrade and expert knowledge of the vehicle's rear differential.
