My XJ has 3:55 gears in my D30,its and auto and yes I have checked! I already swapped in a 8.25 with 4.56 gears in rear and have bought new 4.56 gears and rebuilt kit for the front.From what I ve been reading the new gears won't fit in the present carrier only if it has a ratio of 3:73 or lower?  Can anyone comment on this,I'm getting ready to install and would like to know ahead of time...  Thanks for any info on this... |

You need a new carrier for 3.73 and up 4.10 etc the 3.55 carrier will not work with the 4.56 find one from any YJ XJ ZJ . All d 30 carriers are interchangable . but it must be from 3.73 - 4.10

High and low pinion gearsets are not the same, but the carriers are. ANY D30 carrier will carry hi or low pinion gearsets, even old CJ's.
You are concerned with the 'carrier break'.
This is where the ring gear mounting surface on the carrier is offset to make up for the smaller pinion in lower gears (numerically higher).
the ring gear mounting surface on the carrier is around 1/4" different between hi/low carrier breaks.
Hint for buying used parts - Sit the carriers side by side on end, and see the difference of the mount surface.
