Yukon’s ring & pinion kit went in clean with everything needed in the box. Gears mesh perfectly and the positraction is a game changer on the trails.

Swapped in the Yukon 3.91 ring and pinion last weekend on my Chrysler and the difference was immediately noticeable. My truck pulls harder off the line and highway cruising is noticeably smoother. The kit came with everything I needed, bearings, seals, install kit. Nothing missing. A buddy of mine has been running Yukon gears for years and told me I wouldn’t regret it. He was right. Highly recommend for anyone doing a gear swap.

Regeared my Ram with this Yukon 3.91 kit after towing became a chore with the stock gears. The install kit had every bearing and seal I needed, nothing extra to order. My gear installer said the ring and pinion pattern was spot on right out of the box, which sped up the job considerably. Highway RPMs are more relaxed now and the truck pulls noticeably harder from a stop with the trailer hooked up. Positraction engages smoothly with no clunking. Worth every penny for anyone towing regularly.
