bought this to replace the dented stock cover on the 8.8 Ford in my TJ. Easy swap, looks killer and should'nt dent. If the plugs were magnetic it would be perfect!

Q: If the filler is raised and the unit holds 1-2 more quarts(thats a big difference), then how would you know when to stop filling the diff? Answer this question

A: Hello You would want to fill to the middle of the oval sticker. We us a small bent wire through the filler hole to check level.

Q: I have an 02 Explorer with the Ford 8.8 rear, now I know that this is a extra capacity cover and I realize that the volume capacity would be different but i was just wondering if the fluid level in the differential case would be the same. Answer this question

A: Hello Tom, the G2 Axle and Gear Ford 8.8in. Aluminum Cover part# G/240-2013AL will fit your vehicle and also increases the amount of fluid that the case can hold. It will take about 1-2 quarts more to reach the correct fluid level. Thank you for your inquiry.
