This is our basic differential cover, we see it as the only one worth making. The D30 came in a few different trucks but it primarily came in Jeeps, from the Jeepster in the late 60's, through most of the CJ5, CJ6, & CJ7 years, throughout all of the different Wrangler variations (YJ & TJ), Cherokees (XJ), and of course the Early Broncos. The D30 axle is actually a pretty good little axle if you don't get carried away with too big tires.

One of the questions we get regularly is about the tie rod clearance, it is ~3/4" and it clears all of the D30 axle setups we have encountered.

This Differential cover is a 1 piece Plate steel cap 3/8" (.375") thick bent 8 ways then welded to a 1/2" ring, we had to make it thicker to make enough room for the thickness of the cover, it just happens to make it 30% stronger too! The fill plug is a generous 3/4" ID for easy fill and oil level check. This is arguably the strongest Diff Cover made for a Dana 30 axle.

We manufacture this and all of our covers out of A50 Plate Steel, that's 50,000 PSI Tensile strength. After welding, the mounting surface is machined absolutely flat for a perfect fit! This is for a fully welded D30 Differential Cover with fill plug ready to plug and play.

Steeve on 3-21-2018 Asked: I have a 2013 jku sport with a Dana 30 front axle. Is this a straight on for?

Answered: Yes this will bolt to your dana 30. You do need longer bolts for the thicker cover which we offer as an option when adding this to your cart.

Dennis G. on 2-6-2018 Asked: Would this fit with heavy duty steering? 1996 jeep zj 2 inch lift

Answered: We typically have to add bends to our steering kits to clear diff covers and sway bar linkage. If you want to measure with your wheel turned to full lock you can see if you'll have clearance issues. Our D30 covers sit about 3" off the the mounting surface

Tom D. on 12-21-2017 Asked: Does this work with stock steering? 1998 Jeep XJ-no lift

Answered: Yes it will. The cover is 3/16" taller than the factory one. The tie rod gets pretty close when the steering is full lock, but should not hit if your alignment is correct.
