It's a legit yukon product
Originally purchased one of the from a company in Wa state for double the price, this is a wholesaler which cuts the price drastically. Exact same packaging, product (stamped from manufacturer w/ serial numbers and everything), excellent customer service too. If you need a new locker for your gm 10 bolt this is the best option to replace the stock g80 (gov-lock/ gov-bomb). Ran my first one for 150k miles, didn't know fluid replacement was crucial to clutch longevity. I'll be changing this diff gear oil every 30k. True Yukon gear part, exact replacement for almost all gm 10 bolt rearends. Don't believe the -2 at the end of the part #, it's a ydggm8.5-3-30-1 made in the USA. This was less than half price from the local company that produces them, that company wanted to rip me off, this company sold me my parts at a reasonable price. I'll be recommending them to everone. Thank you very much.

Great price, clean and ready to install, easy install
The part itself was fine, direct replacement for gov lock, easy install and no problems with performance.AMAZON....IF YOU ARE GOING TO OFFER ONE DAY SHIPPING THEN DON'T SHOW UP AT 9PM THE NEXT DAY AND CALL IT "NEXT DAY SHIPPING". YOU ARE PROVIDING FALSE HOPE. WTF AM I GONNA DO WITH A PART THAT ARRIVES AT THE END OF THE DAY. 5PM WOULD BE ABOUT THE LASTEST I SHOULD SEE SOMETHING "NEXT DAY". IF FED EX AND UPS CAN DO IT, SO CAN YOU.

My G80 rear ate itself up like they do so upgraded to this Yukon Dura Grip. So far, so good. Stayed with the stock 3.42 gear.

Life saver!
The rear end of my 2007 yukon xl tragically exploded with a car full of kids. This vehicle is my daily grocery getter and only vehicle we own that van haul all our kiddos. We were stressing about whether to purchase all the needed parts separately at Advance auto, or buy used. My husband has lots of experience with mechanics, but had never changed an entire rear end and found the task daunting. We took a chance on ordering this rear diff because of the awesome price and reviews (we were skeptical.) He had to get a few small parts from the auto store to go with this (bearings, I think and gear oil) but he got everything installed in a day or two and it works GREAT! The truck now drives better than before, no strange noises and it is holding up great through daily use and abuse. Highly recommend this part (you’ll find this exact part for a few hundred more on other websites!)
