Questions and Answers

Would like to know if this would fit my 1999 F-550 with a 10.50" rear?

Answer
As long as it is a confirmed 10.50" rear, then it should work for you.
It says the yukon will disengage while negotiating turns.. What if i have ice or snow around a turn?

Answer
Automatic lockers like the yukon grizzly locker are great for providing extra traction. Unfortunately, this is a double-edged sword as far as slippery road conditions go. Inexperienced drives may find it difficult to negotiate wintery conditions with an automatic locker. In order for the locker to disengage around turns, both tires need to have traction. Once there is a difference in tire speeds, the locker will disengage allowing the axle to perform as an "open" unit. In a low-traction turning scenario, the locker is going to do its job of keeping both tires turning at the same speed but there will not be enough of a speed differential to cause the locker to disengage. In a rear differential application, this would cause the rear end to feel loose and "wander". In a front differential application, this would cause understeer. The vehicle will perform much differently in wintery conditions so drivers will need to make adjustments to their driving habits when using an automatic locker.
