Don't get stuck again!


The four-spring clutch-style positraction has been around for years because of its great reliability and rebuild-ability. Because of its popularity Yukon has released its version – the Yukon Grizzly.™  It’s available for all popular Dana, Dodge (American Axle), GM and Ford applications, and more applications are arriving all the time. Grizzly™ units are assembled with heavy-duty 8620 spider gears and composite clutches for reduced chatter, and they are fully rebuildable. Yukon chose the spring design because of its race-proven background and years of use.
Grizzly Limited Slip Differential are set apart from every other positraction units by:

Its strength, durability and toughness gives you traction when you need it, to getout of the worst situations.  
Patent pending design that improves the center drive for greater durability. Has 8620 alloy steel internals for added strength.  Fully assembled in the USA, Industry leading support and warranty

Performance limited slip positraction units for Street Performance, Hot Rodders, and Off-roaders. These Positraction Performance Differentials feature a patented carbon friction material designed toendure the hostile extremes of Off Road racing brakes and clutches. Made from high-temperature carbon fiber wrapped with a carbon anti-wear coating, these virtually indestructible discs thrive on repeated harsh engagements and thermal abuse, without performance loss. The patented composite clutch fabric maintains its lubricity to provide smooth, quiet operation over the life of the vehicle.

When the traction disappears, your Grizzly locker automatically kicks in, locking the rear wheels together and sending power to both. The result? You and your vehicle keep moving when everyone else is standing still.
