  • Good quality built case!
My tcase was trashed, figured I’d give them a shot since they have good reviews and don’t charge core up front. Have been running the tcase for a bit now no issues whatsoever. I’d recommend this to anyone looking to replace your tcase. Will update again if anything changes! Update: Almost 4 months later still working perfect no leaks or anything! ... show more

  • Super great replacement for my transfercsse
Really well packaged, great customer service. Hopefully I won’t ever need a transfer case again in my 07 2500hd classic but if I do I will buy the same one

  • Customer service was amazing!!!
Great product, great price. The communication to ensure the proper transfer case was sent was phenomenal. So far the transfer case has done its job. Thanks to their note to check your driveshaft yoke probably saved me from having a leak and another bad transfer case.

  • Very good business to work with.
Ordered the transfer case, received it when promised, they paid for core to be sent back, and the truck runs amazing with it. Not even a small seep at any place and I already have 10,000 miles on it

  • Quick delivery
Got here Quick !!! Seems like a solid unit. Great customer service. I noticed a leak with my old transfer case Sunday morning" Duramax pump rub" . I did a little googling and it led me to this company. Crossed my fingers and ordered it Sunday night. The new transfer case was in my driveway when i got home from work Wednesday ( obviously shipping is different for each situation ) Im in NC . swapped it in my garage and I've put almost 1,000 miles on this unit. So far no complaints. checked on it several times. No leaks, no noise, shifts in and out of 4wd no problems. Very satisfied with this company. And For the money spent vs a rebuild, and down time, and ect. This, in my opinion was the way to go. Thanks guys ... show more

  • It works and fits
I got the np263xhd in November (2022) for my 2005 chevy 2500hd. 6.6l duramax. Electric 4x4 selector. I installed it by myself in the driveway. So far no leaks and my 4x4 is working again. So far so good.ill try to update this in a year or so.

  • Great company, lots of help, solid product.
I called to make sure of the proper fitment the tech was very helpful in answering all my questions and taking my info before I ordered. It took about a week or so to receive the unit via UPS standard delivery truck. My neighbor is a master mechanic has his own setup at home had the new unit installed in about 3.5 hrs, I ran the truck through a test drive and in and out of 4 low and high, just like new. ... show more
