Blue Torch Fabworks Kryptonite Differential

I am reviewing Blue Torch Fabworks Dana 44 Kryptonite Diff Covers. I bought 2 of them a while back I must say WOW! I am a fabricator myself and am very impressed with the level of fabrication in these covers. They are top notch. They have traveled over the Rubicon and some other tuff Sierra trails without any issue. They come with great 12 point hardware so you don't over-torque them and squeeze out all the RTV. I definitely recommend BTF products.

When they ship it to you, they have the BTF emblem on it which is ugly. Doesnt take much to get it off though!

I've got both diffs covered with D44 BTF covers they are pretty bombproof. But with all covers they leak

Honestly I have not been able to off-road with these on yet, but just judging by the thickness and structure of the diff covers, these are made to protect well. I have never used any diff covers so I have nothing to compare it to but can assure you its much better than the stock covers.

Have not wheeled it yet--next week--but installation was excellent! Blue Torch provides you w/ allen-head hardware . . . eh, but did not strip out or break--even to the higher torque requirements of a Lubelocker.

Furthermore, the physical depth of the cover is the EXACT same as the OEM stamped steel cover!! All while still providing a 3/16" flange & 1/4" thick body! As a result, the diff took a bit less than than 2qts of fluid--compared to the stock cover spec of 2.1qts.

Because this fabbed cover is no bulkier than the OEM cover, I believe I could now purchase a second cover for my front diff & still clear my Currie Currectlync steering system @ full tuck.

The cover is actually made by Crawltech but is very close to the Bluetorch design (I think they are one in the same), use it with a Lube Locker.
