Completely Assembled Differential equipped with a Grizzly Locker

Our Grizzly locking differentials are 100% ready to drop in. This "ratcheting" type locker is suitable for a daily driver yet capable for competition use. Grizzly Locker is fast becoming the number one choice in automatic lockers. All 3rd members are assembled with trail proven Yukon Gears, Yukon master differential setup kit (most kits feature Toyota OEM Japanese KOYO and Timken bearings), our solid pinion spacer is used in place of the common crush sleeve (note: solid spacer is currently only available for 8" 4cyl, V6 and High Pinion applications) and all 27 spline pinions feature Marlin Crawlers EcoSeal Heavy Duty Pinion Seal.

Every Differential we build comes with our EcoSeal Technology and the highest quality differential gears on the planet. Click an icon below for more information:
