i have a 1984 s10 reg. cab longbed 2.8l 4speed and im putting a mild built 400sb bolted to a built th350 into it and im try to find out what would be the best but easiest rear end to use. i would like to find one that is already posi and bolt up and very little modification to fit. your help will be greatly appreciated.

yea the easiest way i think is find a pull out of s-10 extreme it is a 8.5 ring gear with posi and i think it will be a direct bolt in. or you could do like i did and build a 12bolt with moser stuff,had the axles cut to fit factory width,it cost 2000 and he did all the work.

There are several options and I've seen people go various ways. If your running some serious horsepower and torque, I'd recommend going with the Ford 9 inch. You may not necessarily need a posi unit. One, they are costly, and two they break! If your looking for the posi unit for the Ford, it would a locker rearend. I've seen people go with the Ford 8 inch from Mustangs and they work nicely for your application as well. The Ford rearend is popular because of its simplicity in installing it in various application, plus its strength.

i agree with the strenght and weight of a ford 9in. but man they are expensive unless you do it your self,me i paid too have mine done and i did consider a bolt in ford 9in. but i think i got out cheaper with my 12 bolt.if you dont know how too set them up they can get expensive real fast;thats why i suggested the extreme s-10 rear cause if u can find one its a direct bolt up ; no narrowing or geometry too fig out.They will handle quite a bit of hp.

8.8 out of an explorer. 31 spline,posi, DIRECT bolt-in. Just different offset/lug pattern wheels. I ditched a 28 spline 9" for the 8.8. Absolutely the best rearend swap for s10's.

Did the xtremes have the 8.5? The extended cab shortbox 2wd,4.3,5speed did. Also the ZR2's but they are wider. The 8.5" is a 30 spline with a gov lock isnt it?

I wouldn't say the best swap, But maybe the easiest...

They are stronger than any factory s10 rearend thats for sure.

9" and 8.8 both great rearends. They both have their advantages. c-clips vs. non c-clip. 8.8 has larger axle tubes. 9" has removable center section. 8.8 uses less power at higher rearend rpm's. You really can't go wrong with either. I have had both of these rears in high hp s10's and they both worked great. Moral of the story is pick which flavor you like and never look back.

thank you all for your help. is there anyway to make s10 rims fit on the ford 8.8

ford 9" from a 67 to 77 bronco. width is fairly close

I would go with a rearend out of a 94-2004 S10 usually they are paired with the the 4.3 vortec. It is 3:73 gearin not bad and its a LSD (limited slip

I actually had this housing in one of my v8'd s10's. It worked well, width wise. I think I had moved a spring perches a bit but overall it worked well.
