Works like a charm worth every bit of money pain job could have been better though was just flaking off, but other than that, everything went smooth and was perfect

    • Works as it should
The only complaint I would have is the studs that hold the transfer case to the transmission had too much paint on them, making it difficult to thread the nuts onto them.

    • seems like a good product so far, directions could be improved for best installation outcome
the directions could be updated a bit for completeness. they have many good things in the directions including the bright colored paper. the biggest thing that would have made my life easier would be removing the wire harness mounts before installation in to the truck.. there are 3 that need to be moved over by removing 3 1/2 shell bolts on the old case and then on the new case. it shifts smooth and the installation is easy on thse. ... show more

    • 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

    • 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
