Yukon Gear & Axle (YGK012) Gear & Install Kit for Jeep JK non-Rubicon 4.56 Ratio

Great product, it was a learning process to install as I installed the gears myself. If your not mechanically inclined do not try it yourself. No issues at all and have stood up to some serious wheeling so far.

Everything you need, went from 3.21 to 4.56. Now I’m able to use all gears. Running 35” tires with 6 speed manual. Performance is now back to original factory feel, which I’m very happy with.

I like the fact the kit came with everything you would need and more . If your a weekend warrior and don’t do this everyday I’d get it if your a pro your probably not reading this Anyway 😂😂

Purchased them as recommended by a mechanic. Still have to install them.

Bought these gears in August 2021, had them installed into my jeep JKU with 35" tires in October 2021. Here we are in march 2023 and the pinion gear broke. Vehicle is mainly a pavement princess, rarely even driven on grassy parking lots..... Called Yukon and discovered they only have a 12 month warranty on them by default unless you buy their Y.E.S. extension within 30 days of buying the gears for the lifetime warranty..... I didn't even know about the Y.E.S. programs as I ordered them off Amazon. Very disappointed as I thought I had bought a quality product..... I am now reading reviews out there with similar problems..... Stay away from this brand.... the attached pictures are of the exploded pinion gear after 15 months and 7500 miles of blacktop driving, never in mud once... Cheap steel most likeley or horrible heat treating

great product. I've always had quality parts from Yukon.

Complete kit fit my 2015 JKU perfectly. Running 33’s my power and rpms are back to where they should be.

rear ring and pinion failed in less than a year and customer service is horrible and will not get back to you at all,,, BIG wast of money and yukon says to get with them about replacing the bad parts.. dont recommend to anyone
