I bought a 8.8 rear axle thinking that it would beef up my rear end a little more..well come to the fact..the 2003's 8.8 are the exact same(pretty much) as the 7.5. There is no difference in the "beefiness" or whatever??? I'm thinking about upgrading to 31 spline to make sure nothing will happen. In the future i plan on putting a 4.2 twin turbo in though. I'm wondering if it is worth it. I can get the axle shafts for 267 and get the 31 spline T lok on ebay for 150...

Not to mention that one of my axle shafts in the 8.8 is broke, but they said one from my 7.5 will fit....i'm just wondering if it would be worth it or a waste of 400 dollars?

the 8.8 is better then the 7.5. Take the main ring gear and look that the difference in thickness.

yeah but it has the same axle shafts...there both 28 spline which kinda pisses me off...but wahtever i cant do a whole lot about it....i know the ring gear is different..butshit

if you get 31 spline you'llneed a different t-lok
31spline is much stronger. moser axles are much stronger. you'll be good into the low 10s high 9s with those
if you get 31 spline axles and a 31spline t-lok you'll be set for a long time...get a trutrac and you dont gotta worry about shit on your v6 unless you plan on hitting low 9s or launching off the line with a huge shot of nitrous and slicks

will the 31 splines fit properly with the 7.5 axles? like what i'm asking is do they make 31 spline 7.5 axles?

[itschristorres8]

nope
only 28

I have an 8.8 rear axle. So your saying that it would be worth it to upgrade to 31 spline? and that Tlok that i put a link up to would work...because its for 31 spline right?

[itschristorres8]

yea but you need the 31spline axles to make it work

[Bies08]

yeah...i have the two links up there....one is for the moser axles off of americanmuscle.com and the tlok is from ebay....thats all i need right?

[itschristorres8]

eh idk about buying that ebay one...seeems scetechy
i'll post a link to a decent priced 31spline t-lok

[Bies08]

Whats the difference between that and a tractoin lock?

[itschristorres8]

ive never heard or seen that till just now

[Bies08]

yeah i have no idea what it is...my uncle talked about a spool or something in his chevelle...we started talking bout what im doin and all that..and he said something along them lines..then he told me ot weld the axle shafts together..or weld something together..shit idk?? i just know thats not the best way to go at it...thats by far the worst way...

[itschristorres8]

looks lik a locker....lockers arent the best ideafor everyday street use
