Grannas Racing Ultimate 8.8 swap rear differential cover

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:

1. Four bolt pattern directly in flat face of rear cover to allow building a rear mount easy.
2. High fluid capacity for better gear lubrication, better cooling and less fluid volatility (no catch can required!)
3. Cover has breather port at 2 o'clock position for less "splash out"
4. Easy maintenance - back AND side fill ports allows oil changes while diff is in car
5. Precision CNC machining - always square and will always seal without leaks
6. Deep bowl for big gear clearance. 
7. Load bolts for main cap support when under heavy load.

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: 

1. 2003-2004 mustang cobra (aluminum)
2. 1993-1998 Lincoln MK8
3. 2002-2006.5 Ford Explorer (single front mount ear)
4. 2006.5-2010 Ford Explorer (dual front ear)
5. 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.
