right now i have the stock 7.5 rearend in my ford ranger and i was thinking about switching to an 8.8 rearend. What kind of problems am i going to run into or is it a fairly simple project. Should the 8.8 fit into my drive shaft or do i need to get some type of conversion piece? Any info or help would be great. Thanks.

IF 90 or newer it should be a straight swap otherwise you will need some driveshaft mods

If you're gonna take the time in swapping out axles, throw in the 8.8 from a late model Explorer. It's a little wider, has disk brakes, and it's stronger. It takes a little more work, but it was worth it. You need to weld on new spring perches, get new u-bolts and spring plates, and weld on new shock mounts. Nothing any fab shop or welder that knows what they're doing couldnt do for you. We installed one on a 2000 Ranger.

If you're looking for something to bolt right on, go with the Ranger 8.8.

You could, also, use an 8.8 out of a Mustang. They have disk brakes, too. You do have to weld new spring perches on.

and get new axles or drill the proper bolt pattern into them.

thanks to all that replyed. That information helped a lot. So should the wheel or lug pattern be the same if its off of an explorer or 4.o ranger of a newer model?

I may be incorrect but, the flange or the rear end is different. I put a 7.5 in my yota, and had a driveshaft end from an 8.8 and the flange on the 8.8 has a bigger diameter bolt pattern. (89-90 rear end and 93 driveshaft end)

You are right Pat the newer 7.5s and 8.8s use the same stuff its teh older 7.5s that dont work...this was due to the 4.0 being introduced in 90 I think and they didnt update all teh driveshafts yet.
