A girdle cover w/ preload bolts stiffens up the housing and helps stabilize the differential, but does nothing to the "weak link" in the 7.5" 10-bolt, which is the pinion / bearing / housing area. The shorter distance from the nose of the pinion to the rear axle C/L results in more reactionary force being applied on the nose of the pinion for a given tire-torque level than for a 8.5" or larger rear. If you have an auto and stock-ish street tires, it'll probably hold up (and produce nice smoke-shows), but meaty rear tires and hard launches (or hard shifts w/ a manual) will kill it, even at stock-ish power levels. Ask me how I know.
My recommendation is to not drop a dime on the 7.5" 10-bolt and upgrade to something beefier.

if this is a f body your talkin bout yes you have a straight axle . me personally i wouldnt put much money in it ( ive blown 4+ and dont have much faith in em) others will say they can live a OK life if auto and no sticky tires but ive killed every 10 bolt ive ever owned, a strange s60 with a s trac will live through almost anything. go look at midwest chassis to get an idea of what your getting into.

What gear ratio were you guys running when you killed them so easily?

3 of them 3.23 with ls1 stock internal, stock head ,big cam , intake/headers/true dual ,3600+ stall ,umi long arm , legit street tires no drag set up at all. the other two were in s-10 square body, belive it or not a hopped up berreta 3.4 motor with nitrous, in place of a blown turd 2.8 . i just cant do the hole 10 bolt thing..... now a full size truck 10 bolt (8.5 ring) can live if you stud the main caps use a good locker and a diff girdle, thats what my procharged 4.8 with nitrous and 35 in tires and 4.88 gears was rockin, i dont have it anymore but still see it out on the street every now and again. looking at op last post i think he has a hummer h3 truck im guessing, and that might be a 8.5 10 bolt.

Sadly there's like.. 3 people on the h3 forums making any decent power. The h3 does have a 8.6 for the rear. But a 7.6 for the front. I feel like my only options to go with less power or do a solid axle swap

7.5 is garbage. Call quick performance. Won't cost 4k. Maybe 2800-3200 for rear end. If you get a new torque arm and lower control arms then I'd see it getting closer to 4k. But if you plan on making 500hp then you should already have these things...

This right here. State some details not something about on par of trying to get information out of a 6yr old.
People expect you to read their fckn minds....
For everyone else who hasn't caught it yet from the very detailed initial post, this is the FRONT Diff in a Hummer H3....
