D44 30spl, 3.92 & UP GRIZZLY LOCKER

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.

• 3.92 and up ratio only
• 8620 internals for added strength
• Assembled in the USA
• Fits Dana Spicer 44 with 30 spline axles
• Patented internal design reduces common locker failures

Technical Notes: This unit will not work with early tapered axle designs that used an axle spacer button. This unit is drilled for 7/16" ring gear bolts. If using in an application with 3/8" bolts, please purchase (10) YSPBLT-027 spacers.
