Description
Lighter and Stronger. If you are upgrading the rear gears in your SVT Cobra, it's a good idea to replace your wimpy stock Girdle Support System (a.k.a. differential cover) with a super strong, light weight Aluminum Differential Cover for additional safety and peace of mind.

Superior Construction. Made in the USA, this 8.8" Rear End Differential Cover is cast from heat-treated aluminum for strength and features magnetic fill and drain plugs, additional clearance for billet main caps and low gear ratios, and increased fluid capacity for reduced operating temperatures.

Recommended Upgrade. When changing your differential cover, it is recommended to upgrade to fresh Royal Purple Synthetic Gear Oil. You will need 3 quarts of Gear Oil.

Application. This Aluminum Rear End Differential Cover is designed to fit the 1999 to 2004 SVT Cobras equipped with the 8.8" Independent Rear Suspension (IRS) rear end. Not for use on non-IRS Mustangs.

Note: Not compatible with Steeda Differential Cover Brace.

    Perfect!

    Amazing piece!!! Thicker than stock and one thing nobody has hit on yet is the set screws to put pressure on the interior C brackets that hold the bearing in the sleeve! This is SOOOO important as if one of those break you have to buy a complete housing which is backordered from Ford until 2011! know this because mine broke - Luckily found one in a pick and pull - Hope this helps! A+ to buy this! It also has a drain plug and the factory ones dont

    Great Cover

    Awesome product. However 3 quarts is too much oil. It was spilling out at the end of 2. Looks great and will hopefully not break!!

    This cover looks great and is superior over stock.

    great fit, I had to remove the pumpkin to have enough room to install, well worth the added strength and protection. Looks great .
