REVIEWS
Installed the Yukon 4.56 gears in my Chevy 2500HD and the torque is insane. Perfect for towing my boat and still smooth on the freeway. Couldn’t be happier.

Put these gears in my Ram 3500 for hauling livestock trailers. The 4.56 ratio gives me all the pulling power I need without sacrificing drivability. Yukon nailed it again.
