REVIEWS
I installed the Yukon 4.88 kit on my Rubicon before heading out to the Rockies. The torque boost was unreal—my Jeep handled steep climbs like a champ. Everything fit perfectly and the quality is solid.

I run 37s on my JK Rubicon and needed better gearing. This Yukon kit was the perfect upgrade. Easy install with the overhaul kits and now I’ve got the power I was missing. Highly recommend!
