MIA's Description

The Motobilt DIY Heavy Diff Cover is a weld-it-yourself protection kit for the 2017-2021 Ford M275 Super Duty 14-bolt rear axle. This kit addresses factory vulnerabilities by providing a robust, thick steel barrier against off-road punctures and edge damage.

The assembly includes a laser-cut 3/8-inch steel ring and a CNC-formed 1/4-inch steel shell. All necessary mounting hardware and an oil fill bung with a standard pipe thread plug are included, arriving in bare steel ready for your choice of finish.
