The Yukon Grizzly Locker is a mechanical locking differential. It features a forged case and 8620 internals for maximum strength. It's patent pending design reduces common locker failures. All units assembled in the USA! This locker is designed for a stock truck axle shaft. We also have the 38 spline upgrade kit in a separate listing.

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.

2008 Chevy Duramax With Yukon locker
I purchased the Grizzly locker 1 year ago for my 08 Chevy 2500 hd. My truck is used to pull 15000 pounds gross weight of hay on a 25' gooseneck from Colorado to AZ 4 times a year. My truck is also used for hunting, cutting wood and normal family use. I chose an auto locker because I wanted 100 percent reliability on and off highway. The Yukon locker is very quite and in the hd I have no rear diff/drive steer. Cornering with the trailer is a non issue as well, I simply goes easy on the throttle and the weight of the load keeps the locker from engaging. The down side to the Yukon is, compared to the Detroit locker I had in my 96 Gm half ton for well over 150000 miles, there is noticeably more gear slop when in traffic coasting on and off throttle. The gear slop may be more noticeable because of the heavier rear axle and more torque/throttle response of the Diesel VS my 96 1/2 ton with the 10 bolt which is much lighter. Drive steer was a given and a non issue in the 96. In fact compared to the factory eaton govi-never lock performance, I learned to love the slight engagement drive steer. With both trucks and knowing the surprise engagement of the locker on icy roads, I engage the 4WD to avoid any lockup side ways drift. Although I must note that in the 08 and the heavier axle and the Yukon locker when in 2WD and on ice covered roads engagement drift did not occur. I will continue to engage 4WD around congested traffic just to be sure to avoid the possibility of engagement drift. If I had the opportunity to change differentials I would go with a torsenal for the gear slop alone. Since I have an air locker up front and the use of breaks would still allow engagement of the torsenal diff when one wheel is off the ground, less than 100 percent lockup would be acceptable. In the case of the half ton where a front locker is not a possible option, I would stay with the auto mechanical locker and you can't beat Yukon's warranty.
