Differential Covers FAQ
Should I shop differential covers by Jeep model or axle model?
Start with the axle model, especially on a Jeep with an axle swap. Confirm the housing, front or rear location and vehicle application on the product page. Two axles with a similar name can require different covers.
What is the difference between a welded cover and a DIY cover kit?
A welded cover is assembled by Motobilt. A DIY kit supplies the components for you to weld together. For example, the 14-bolt DIY kit includes a formed shell, mounting ring, fill bung, plug and mounting hardware. Use an experienced welder and test-fit the assembly before finish welding.
Are all 14-bolt differential covers interchangeable?
No. GM full-float, GM semi-float, shaved 13-bolt and custom ECGS/Fusion housings have different products. Ford M275 also uses a 14-bolt cover pattern, but its cover is not interchangeable with the GM Corporate 14-bolt cover.
Which cover should I choose for a JL, JLU, JT or Bronco?
Identify the axle designation first. This collection has separate M186, M200, M210 and M220 applications, and a dedicated Bronco M220 product. Match the vehicle and axle description together; do not assume every trim or every M-series housing uses the same cover.
Do the covers arrive painted, and is hardware included?
Many Motobilt welded and DIY steel covers ship bare and need a finish. Hardware and fill-plug details are listed on each product page. Check the exact cover rather than assuming every cover, skid and pinion guard has the same contents.
Is a pinion guard the same thing as a differential cover?
No. A differential cover closes the housing over the gears. A pinion guard protects a different area of the axle, and the Rockwell products are skid-cover designs. Choose protection for the part of the axle you are building, then verify clearance with the truss, steering and suspension.
