trying to decide what axle to run

[t_ank]

well currently im back and forth been doing alot of reading and have decide what i want to do.

im running a 10 bolt 7.5 open diff with 3.08

i want something more and dont want no more one wheel peel

was thinking

1. 8.8 with 3.73 or 4.10 and factory limited slip (would have to be narrowed unless i ran a vette wheel or that offset)
2. i found a 10 bolt 7.5 factory limited slip w 3.73 for 200 bucks


but i have read 10 bolts are junk

just not sure what i want to do. its going to be a summer dd weekend warrior street and strip. i dont want to spend a alot of money right now into an axle thats why i started leaning to #2 its cheap and will do what i want but when it going to break?

my goal for this season is to get drag radials 373 or 410 posi and a tune and see what she has at the strip and then i have something to compare it to in the spring when i do some winter improvements

Is an 8.5 10 bolt a direct swap? They are pretty stout and have been well into the 8's.

A 7.5 axle is junk and every penny spent on one is a penny wasted.

8.5 from a ZR2 will need to be narrowed from 63" to 54.5"

i think they are bolt in but i think its longer im trying to find it now

2wd 54.5"
4wd 59"
ZR2 63"

i could work with the 4x4 8.5 but to find it with the 3.73 limited slip

[hoogiesngrinderz]

4x4 is still a 7.5/7.625, only the ZR2 got the 8.5

well damn lol

Scott at DLS can cut down a ZR2 axle, I forget what he quoted me though as it was many years ago

hmm ill see i still think a 8.8 would be better if i had to narrow it hmmm

`i have done alot of v-8 S-10's both ls1 and lt-1 along with 1st gen engines in about any body style S-10 you can think up. i would run the 8.8 from a 96 ford exporer. it has disc breaks. you will need to re-drill the axle shaft to 5 on 4 3/4 lug pattern along with the brake rotor.

there is 2 other options you can go with. 1 i dont recomend for a ls1 powered S-10

the V-6 rear end was a 7 5/8 ring gear alittle stronger but not enough.

the chevy S-10 ZR2 had a 8" or 8.5" cant remeber which. but they are hard to find.

i like the 8.8 becouse it alot like a 9" gear changes are simple and quick aspecially if you have 2 third members set-up.(one for street one for race)

if you need anymore info just yell.

zq8 2wd manual trans "should" have a 8.5. it was an option on most models. my 94 had a 8.5( wore the carrier out around the diff pin twice LOL)
the 8.5 cover is round.

If your going to have to narrow it the 8.8 is probably your best option. There are tons of parts out there and they came in everything.

FYI an 8.8 is nothing like a 9" when it comes to gear installs. They use a standard cast iron housing and do not use a 3rd member.
