Gears & Axles - 4.30's in 10 bolt are still holding up

I put 4.30's in my 10 bolt & have drove it pretty damn hard since then (about a month) and am having NO PROBS at all so far.....It feels alot torquer & responsive as hell.....barely a whine at high speeds but am very happy so far:) By the way, thanks Kaliente for the awesome write up, my father & I did the installation & it only took 2 hrs to do.....we didn't experience any complications whatsoever :headbang:

glad to hear it. go 10bolt go...

knock on wood

what tires are you running

Are you leaving hard? Hooking well?

Just let street tires spin, it'll save the 10-bolt. When you add slicks and hook that's when it's toast.

I abused my 4.11's with a cammed Incon Twin Turbo making 600+ rwhp and my 10 bolt held. :drive: They just spin when you floor it in 4th gear on the interstate. :jest:

Yes, I'm on trans am chrome's 245/50/16's Fuzion Zri's.....They hook pretty good.....You said it exactly right, add slicks then kiss 10 bolt bye bye :judge:

I feather the clutch, haven't really tried to launch it hard.....toooo scared too:)

Just curious as to where you found 4.30 gears for the stock 7.625" 10 bolt rear. I usually see the gears jump from 4.10 - 4.56's in the catalogs.

You know you are asking for trouble by saying your 10 bolt is holding up :jest: Don't jinx yourself!!

Glad my install page could help you out, enjoy!

They came in Isuzu's and mail trucks.

LOL, I know.....living on the edge :eek2: When I was doing the install, the internals look brand new....no wear at all, I was truly amazed how clean everything looked.....matter of fact I used pretty much all the original bolts, pinion bearing & crushsleeve & everything lined up perfectly. I did change my pinion seal while I had it apart but everything was easy as pie :drive: I used a lift which made the install alot easier......maybe I'm lucky with how everything turned out, installing gears was a cinch :)

Whenever u do get ur 9" in dont install er right away....get some MT's take to the track and see how high u can get the front tires off the ground!!!!!

just get AAA right before it and cancel it after that month haha

Can you buy 4.30's new??? anywhere?

Exactly right....mine came out of an Isuzu Hombre I believe......only went from 23mpg to 21mpg mixed driving......the car pulls freakin hard, very happy so far:)

Cool, so you bought them used? Or ordered them from a stealership? I have 4.10's now... I want to see where they put me in the lights. 4.30's might put me at a better spot going through the traps. Plus, I'll know what I want inmy 12 bolt when I can afford one. :devil:

I bought them used for $80.....was gonna get 4.10's, but since the 4.10's are $200 (GM gears) I figured the 4.30's was a no brainer, purchased em on ebay, they looked brand new when I got em:)
