Differential Covers

Differential Covers: protect and cool the gearset behind your axle

A differential cover bolts to the back of the axle housing and seals in the ring, pinion and carrier along with the gear oil that keeps them alive. Beyond just holding fluid, aftermarket differential covers add material where the factory stamped steel is thin, resist dents from trail rock and road debris, and many increase oil capacity or add cooling fins to hold temperature down under towing, wheeling or track heat. Fit one when you have upgraded gears, wheel hard, tow heavy, or have simply cracked the stock cover.

What we stock

There are 104 products in this category from 8 brands. The current price range on what is in stock runs from $64 to $901 - not a fixed price, but the live spread as inventory moves. Yukon Gear & Axle makes up the bulk of the range with 52 items, followed by ARB with 19, aFe with 15, and Banks Power with 8. Ford Racing, GReddy, BD Diesel and OS Giken round out the list. Coverage skews toward Ford, GM, Dodge and Ram trucks, with Jeep Wrangler, Nissan Titan, Chevrolet Corvette, Subaru BRZ and Mazda applications also represented across model years from 1963 to 2024.

How to choose

The split is mostly between plain protective covers and covers that also do work. On the lighter end you have straightforward finned or machined covers that add strength and some cooling, like the aFe machined black cover for 15-17 GM Colorado and Canyon 12-bolt axles. Sport applications lean toward expanded-capacity designs, such as the OS Giken expanded-capacity rear cover for the 2016+ Miata ND or the GReddy cover for the FR-S, BRZ and 86, which add fluid volume for track use.

At the top of the range you are usually paying for a complete kit rather than a bare cover. The BD Diesel front and rear cover pack for 03-13 Dodge 2500 and 03-12 3500 covers both axles at once, and Yukon's master overhaul kits - like the kit for 2011+ GM and Dodge 11.5in diffs or the Tacoma and 4Runner electric-locker kit - bundle the bearings and seals you need for a full teardown. Match the cover to your exact axle, not just the make.

What else you need with it

Pulling the cover is the moment to address the parts inside. Browse Differential Components for bearings, shims and setup hardware, or Differential Lockers if you want traction while the housing is open. If you are chasing a bigger drivetrain refresh, see Axles and the wider Clutch Components section.

Fitment and ordering

Only some listings carry full fitment data, so confirm your exact axle and year before buying. Call 813-535-5801 for fitment help, or use the fitment calculator. All orders ship free, and Affirm and Katapult financing is available on the bigger kits.
