OK im not sure if this belonged here or advanced but anyways right now i have a 92 laredo automatic with 4.0 and 3.55 gear with a 8.25 and dana 30, im looking into getting military takeoffs since i found a great deal on some i know that i am going to need to regear so that i dont destroy anything while offroad. what gears would you recomend i should get this is also my DD and wht are all the parts that i would need to make this work? thanks in advance

 

I'm running 4.56's with my 36's. I'd go atleast that or possibly 4.88's

 

how does it run with the 4.56s?

 

not too bad, but its hard to tell since my motor is so worn out. I wish i would have gone with 4.88's. Especially since I might go to a 38 later on.

 

with the 8.25 rear the tallest gear available is 4.56 i believe. or at least it was when i built mine the first time.i have a 92 also and i have been running 4.88 for many years with either 35's or 36's and it runs fine even towed the toys when it was a DD. 4.56 would be a whole lot better than whats in there now.

 

yea cuz i have 32s now and can feel a little bit of power lost so i think either one would be a good choice but i cant find anyone to sell a carrier for 4.56 or 4.88

 

I'm running 4.56's with my 36's too.

 

If i remember right the carrier covers from 2.71 and higher. but with the 4.56 the gear place had to grind a couple teeth to fit the cross pin but i had no issues with it. just need to make sure you get the right spline either 27 ot 29.

 

thats probably why i cant find any carrier for the 8.25 and only the d30.

4:88s with 36s and i can spin the tires on the pavement with ease

4.88's have been available for quite some time for the 8.25" axle.

 

sorry about that it has been a while since i had the 8.25 and purchased gear. did not mean to give bad info.
