1 review for Yukon Grizzly Locker for GM & Chrysler 11.5″ with 30 spline axles

  1. Scott Richey

    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.

    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.
    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.
