USA Standard Gear set - Not YUKON - But still good!
Got this for excellent sale price and then when box came said USA Standard Gear and not Yukon, I then called Yukon and where customer support informed me the item is incorrectly listed as a Yukon set in error. Amazon again is listing incorrectly, but the set is still similar to Yukon with the only differences between sets is Yukon has extra crush sleeve x2, and Timkon bearings, where the USA Gear set has Koyo bearings. That in a nutshell is this kit which is still excellent and made for Yukon Dura-grip carriers or Eaton Posi units, (per Yukon customer service), but always verify your aftermarket carrier before hand will accept these bearings or things will not fit correctly.

Product didn’t work for my 06 Silverado rear end. Bearings are different and return window has been closed because I took to long to rebuild it.
