Blowout Sale Diy 14 Bolt Diff Cover Motobilt + Gift Included [OIps2xfi]

If you can weld and want to build your own diff cover, purchase the 14 Bolt DIY DIFF Cover. Motobilt DIY Diff Covers are the same as our fully-welded diff covers,but sold as a kit including the pre-formed pieces and hardware you will need to complete the DIY project yourself. We have included assembly instructions as well.

Why change out your diff cover? We do get asked this question on occasion. The factory diff covers are too thin for abuse on the trail. One of the common factory diff cover failures occurs when the edge gets peeled up from a rock sliding across the diff. Peeling can cause the differential fluid to leak out unknowingly and the result could be damaging the gears when you hit the road to drive home.

Another failure of factory diff covers are from bending the cover into the ring gear which rubs a hole through. The result here is the same with differential fluid leaking out. One other failure is actually puncturing the factory diff cover with a sharp rock. Again resulting in differential fluid leaking out.

Hopefully this explains the need for a heavy duty diff cover. The Motobilt Heavy Duty Fabricated Diff Covers address the failures I have mentioned to ensure your ring and pinion gear sets are well protected.

All Motobilt Diff Covers include a Lifetime Warrranty from trail damage and manufacture defect. We cannot warranty DIY Diff Covers being welded incorrectly.

Simplyweld it together and bolt it onto your axle. Simply weld it together and bolt it onto your axle. As with all Motobilt DIY parts, we recommend having an experienced welder handle the welding.

Installation Note: We strongly recommend tacking the pieces together and test fitting it onto the axle before finish welding. We also recommend using pipe thread tape for the fill plug.
