The Ford 8.8 differential is a strong, affordable option to swap into many chassis. It is independent rear suspension, so it is a great swap to strengthen up the rear end in modern IRS street cars.
Advantages to the Ultimate 8.8 cover:
- Four bolt pattern directly in flat face of rear cover to allow building a rear mount easy.
- High fluid capacity for better gear lubrication, better cooling and less fluid volatility (no catch can required!)
- Cover has breather port at 2 o'clock position for less "splash out"
- Easy maintenance - back AND side fill ports allows oil changes while diff is in car
- Precision CNC machining - always square and will always seal without leaks
- Deep bowl for big gear clearance.
- Load bolts for main cap support when under heavy load.
- 3.5" overall height of the cover itself (cover flange to rear mounting surface)
The cover also features a breather port, a rear fill port, a side fill port, and drain port.
The cover is designed for these IRS 8.8 cases:
- 2003-2004 mustang cobra (aluminum)
- 1993-1998 Lincoln MK8
- 2002-2006.5 Ford Explorer (single front mount ear)
- 2006.5-2010 Ford Explorer (dual front ear)
- 1989-1997 Ford Thunderbird (cast iron)
I offer this with a "universal" bolt on mounting plate has four countersunk bolt holes CNC matched to the cover. This plate will give you a nice head start on getting your differential mounted in your rear subframe.
