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.
Technical Notes: 45mm Bearing Journals, uses TK LM603049/ LM603014 bearings. On rear C-clip applications, the RH bearing cap must be removed to removal and install the x/p bolt. 4.56 & UP ratios may have to grind one R/G tooth for X/P installation & removal.
