Yukon Gear High Performance Ring & Pinion Gear Sets - Durable Off-Road & 4x4 Upgrades for Jeep, Truck & SUV

After I wrote the review below and gave them a 1 star rating, I called again and was able to get through to someone who oversees the Amazon orders for Yukon Gear. He apologized for what had happened and said that some gear sets had been boxed incorrectly and they thought they had got them all pulled from the shelves but obviously one had slipped through. He made the exchange directly shipping me the new one and sending a RA to return the incorrect one. I had to send pictures of the box labels and contents though. Yukon Gears has a good product overall. I have used then since then with good results. I would suggest calling Yukon Tech support first and get the exact part number before ordering the item from Amazon. Changing to 4 stars.Original review: Yukon Gear can give you the right part number to order if you have the unit taken apart and can measure everything and count the spines. If not it can go really bad for you. I ordered a ring a pinon set plus a complete master rebuild kit. Both were wrong. What is worse is by the time I had a long weekend to take a part and install, I was outside of Amazons return window. Called the manufacture and they didn't have the right gear set and can't get it, and said the couldn't help at all. And of course there is no way to get ahold of Amazon now that the return button is gone. So I am stuck with over $500 in parts that I can't use.
