Hey guys, im thinkin about upgrading my 8.8 with 4.10's and a 28 spline to 4.56's with a detroit locker, any advice or suggestions, i intend on gettin a suspension and possibly a body lift to fit 35's

 

for 35s you will want At A Minimum of 4.56s! i would suggest 4.88s with 35s, it will take a lot of stress off the transmission....

i was running 4.56s with 33s and it cruised the highways fine.
i am stepping up to 35s soon and will have 5.00 gears for daily driving and 5.47s for the dirt.

and i am talking to my friend who builds rearends all the time about this...

 

any suggestions on a good place to find 4.88's with a 28spline? and what're your thoughts on the detroit locker? worth it or no?

 

4.88's and a detroit with 35's on a 31 spline?
If you're going through all of that, why not start with a stronger 31 spline axle?

 

quickperformance.com is where i got my gears...

my friend said run a true trac.. didnt ask why.. just what he told me... tru trac, spool, or open is all he wil ever run...

 

yea i decided the locker probably isnt worth it cause im not gonna be wheelin it all the time, but i got a 28spline axle so im trying to work with that instead of having to get a new axle and having to drop the old one and install that one

 

you'd be going through some tires if you ran a locker on your daily driver. i know they make a soft locker that only engages when needed. i don't know all the facts on it but i know they make'm.

 

get 4.88 (don't think they make them for the front diff though) so go with 5.13's..

 

Yes "they" do.

 

yea i think im gonna go with the 4.88's just to put a little strain as possible on the transmission with the 35's, but before all that i gotta find a suspension lift cause i cant fit the tires without the lift and theres no point to the gear without the tires
