Are you in the market to replace or upgrade your Rear Differential Cover? If so, this finned aluminum cover with cooler ports (M-4033-KA) from Ford Performance is a great solution for the enthusiast that wants to push the limits of performance in his 8.8” solid rear axle housing. Originally found only on the 2013 and 2014 Track Pack Shelby GT500 Mustangs, this cover is an excellent upgrade for the Mustangs owner that expects a high level of dependability even in the most strenuous of driving situations!

Features and Benefits:
- Reduces Gear Oil Break Down
- Increases Gear and Bearing Life
- Cooling Fins Reduce Gear Oil Temperature
- Cover Machined for Differential Cooler Pickup and Return Fittings
- Includes 10 Hex-Head Bolts with Anaerobic Yellow Thread Locking Compound
- Cover Machined for Temp Sensor with M10 X 1.6-6h Threads

This Rear Differential Cover from Ford Performance (formerly Ford Racing) is cast from aluminum and showcases cooling fins to help decrease your gear oil temperature and lengthen the life of your gear and bearings. Because of its finned aluminum design, there will be a slight increase in the strength of your rear end housing. The fluid capacity of your rear end housing will stay unaffected but this cover also features two drilled and tapped cooler ports that have the necessary 1/2-14 NPSF block off plugs installed. These cooler ports are also ideal for use as fill and drain ports. Lastly, another great advantage to this cover (M-4033-KA) is that there is a sealed machined port for a temperature sensor with M10 X 1.6-6h threads.

*Fits all 1985-2014 V8 and 2011-2014 V6 Mustangs except 1999-2004 Cobra's equipped with IRS (Independent Rear Suspension).
*Fits ALL 8.8" Ford Rear End Housings, Except 1999-2004 IRS.
*Will not Fit IRS Differentials or with Differential Mounted Anti-Lock Brake Exciter Ring.

We’re here with the finned aluminum differential cover fitting all 1986 through 2014 8.8 rears from Ford Racing.

This finned aluminum differential covers the factory cover found on the 2013 through 2014 Track Pack GT 500, but will fit any solid axle 8.8 rear end and is a direct replacement for the factory one. The finned aluminum is going to dissipate heat better, and has these two plugs built into it. On the Shelby these are used for a cooler, which can be added to any 8.8 rear with additional parts. If you're not using it as a cooler this works great as a fill, and then a drain plug as well.

This includes the necessary bolts for installation but will require the use of silicone for install. This Ford Racing differential cover is a low-profile design so it will clear almost all factory and after market panhard bars.
