14 Bolt 3/8" Differential Cover

14 Bolt 3/8" Differential Cover

  • Ring and Cover are 3/8" thick
  • Plate steel CNC bent 8 ways
  • Machined absolutely flat for a perfect fit
  • All seams welded inside and out
  • Optional bolt kit comes with (3/8) 12 point bolts with washers
Note: Our world famous beefy 3/8" thick differential cover fits the full float 14 bolt axles and will mate up fine with your ribbed 14 bolt axle. However, the additional bolt kit that we sell WILL NOT work with the Ribbed style 14 bolt. You will need to reuse your factory bolts (if they are long enough) or purchase new metric bolts with thread pitch (M8 X 1.25)

This is our basic differential cover, we see it as the only one worth making. The Corporate 14 Bolt axle is found in Chevy 3/4 Ton Suburbans 3/4 & 1 ton GM trucks, what they end up in is up to you.

The differential cover is a 1 piece 3/8" (.375") plate steel cap bent 8 ways then welded to a 3/8" ring! One of the reasons it is so strong is that we manufacture it out of A50 plate steel, thats 50,000 PSI tensile strength. After welding the mounting surface is machined absolutely flat for a perfect fit! It's a great addition to the already near bombproof 14 bolt axle.

This one has seen a bit of abuse and look! No Leaks! I think this one is the best testimonial available, I can't say it better than the Picture can!

By Anthony Sweigart in TX on 5.18.2016
I did a lot of research and found Ruff Stuff to be the much better choice. These covers are indeed beastly. They are made incredibly well and the people who build them have been there done that for quite a long while. Definitely going to be a returning customer. Price is right too!

By Nathan Mascolino in VT on 4.12.2016
I ordered this cover to replace a smashed up home made unit that came with a 14B I picked up. This Cover is beyond nice. So nice in fact I am going to order one for my D60

By Johnathan Wilson in TN on 3.26.2016
If you need a diff cover that can take a beating buy this you won't be disappointed.I ordered this along with the Dana 60 cover and couldn't be happier with my purchase, they were packaged well and arrived quickly. I would buy this again in a heartbeat.

By tyler course in AR on 6.17.2015
As a first time customer, I didn't know what to expect from this company, but I am very impressed! These covers are the real deal! They look great and I feel confident that my gears will be well protected far beyond the life of my rig.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Beefy
By Jake in CA on 3.5.2015
Just had gears done and purchased this to ditch the stock cover, this thing is beefy well built, the mechanic was also in shock how nice it was. Need a cover to protect the internal investment this thing is it.

5 out of 55 out of 55 out of 55 out of 55 out of 5 A must have in the rocks
By Trent Trennepohl in TX on 8.26.2013
I wheel my truck in Clayton OK., Bridgeport TX., and Katemcy Rocks in Mason TX at least once every year as well as our local playground and a few other locations as well. This Diff cover has been pounded against rocks a few times with my 5,000lb rig over the last 2 years it has been on there and even tho it has been missing the bolt on the bottom left since the day I put it on it hasn't leaked a single drop out of this cover. It was worth every penny just for the piece of mind.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Tough Cover
By kirk johnson in NV on 4.20.2013
Super tough cover can really take a smashing and still look good and no leaks. real happy

4 out of 54 out of 54 out of 54 out of 54 out of 5 Burly cover, but needs more info
By Brett Davis in UT on 10.1.2012
I received the cover, very beefy. Welds look great. Installed with a lubelocker gasket. Bought longer flanged bolts. Started to install it...but wait: flanged bolts will NOT work with this cover. I guess I'll go buy regular bolts and washers tomorrow. Bummer. Wish it would have come with a warning, or offered with the correct bolts.

Questions and Answers

Ask a Question


Samantha A. on -- Asked: What size and length bolts got a Dana 44 front cover and 14 bolt cover without bolts I need the bolts

Answered: The 14 bolt cover bolts we provide are 1" in length plus a washer and measure 3/8" in diameter. The dana 44 bolts are also 1" in length with washer but are 5/16" diameter.
Robert on -- Asked: I like the differential cover 14COV, I have a 2002 Chevrolet Silverado 2500HD 4X4 that I would like this cover for. However is there any chance that a fill and drain plug could be installed? Our Answer: We do have plugs listed on the website for the end user to install but that is currently not a service we offer for our covers. New question: Is there any way that you can contact me if you decide to offer fill and drain plugs installed in the dideferential cover, or recommend a shop that would be able to do the modification?

Answered: It is not a service we offer but we do sell the bungs and plugs for someone to add to them
