Yukon Gear Grizzly Locker, Model 35, 30 Spline Axles, 3.54 & Up
Yukon Gear part YGLM35-4-30 is a Grizzly Locker engineered for the Model 35 differential with 30-spline axles, for gear ratios of 3.54 and higher. The Yukon Grizzly Locker is a mechanical positive-locking differential built for rock crawling, serious trail running, off-road racing, and drag racing, providing 100% power to both tires while still allowing disengagement in turns.
Key Features
- Mechanical positive-locking differential
- Provides 100% power to both tires when locked
- Patented inner clutch teeth design with larger base radius for up to 350% greater strength versus back-cut designs
- Resists breakage from shock-loading or catastrophic axle failure
- Fits Model 35 differential, 30-spline, 3.54 and up ratios
Fitment
Fits vehicles equipped with the Model 35 differential, 30-spline axles, in gear ratios of 3.54 and higher. Confirm your exact differential, spline count, and gear ratio before ordering.

FAQ
What does the Grizzly Locker do?The Grizzly Locker is a mechanical locking differential that delivers 100% power to both wheels for maximum traction, while still allowing disengagement for turning.
What differential does this locker fit?This locker fits the Model 35 differential with 30-spline axles, for gear ratios of 3.54 and up.
Why does the gear ratio matter for this locker?This specific locker version is designed for use with 3.54 and higher ratio gear sets; a different locker variant is needed for lower ratios.
Is professional installation recommended?Yes. Installing a locker requires differential disassembly and precise setup, and should be performed by a qualified technician.
What makes the Grizzly Locker stronger than competitors?Its patented inner clutch teeth have a larger base radius, offering up to 350% greater strength than back-cut designs, resisting breakage under shock loads.
Is the Grizzly Locker good for daily driving?Lockers change on-road driving characteristics; many owners use them primarily for off-road use rather than daily street driving.
Does this include a ring and pinion gear set?No, this listing is for the locker only; gears should be ordered separately if needed.
Do I need to confirm fitment before ordering?Yes. Confirm your exact differential, spline count, and gear ratio before ordering.
Installation Instructions
- Remove the differential cover and carrier assembly.
- Remove the factory open differential or locker.
- Install the Grizzly Locker into the carrier housing.
- Reassemble the carrier and torque all fasteners to specification.
