Differentials FAQs
How do I know which Dana axle I have?
Look for the axle tag, the housing shape and the cover bolt count, or check your build sheet. The vehicle selector can also narrow it by year. If you're unsure, call us before you order.
Does a heavy-duty diff cover make my axle stronger?
It can protect the cover area from impacts and may hold more fluid, but it doesn't change the gears or housing strength.
Will an Artec cover fit my Jeep Wrangler JL?
There are listings for JL M200 rear and M186 front. Check which axle you have.
Do I need to change the gear oil?
Yes. Any time you remove a cover you'll need to refill with the right gear oil, and check whether your axle needs a friction modifier.
Are lockers sold here?
A small number are listed. Lockers depend on your axle and gearing, so read the listing and call (920) 249-7744 to confirm it suits your vehicle.
