so pretty soon im guna be getting a D44 rear out of an 87 XJ. im going to put new gears (4.10) in it along with the front D30. on Superior's website, D44 R&P is 4.11 and there front D30 R&P is 4.10. just want to make sure, will that 0.01 affect anything, or do they have to be EXACTLY the same?

You're good. Since you won't be using it on pavement the wheels will slip a little enough to make it fine. Although I think the actual R&P tooth counts are the same, just rounded differently for the two, no?

Jeepjunky

well it will see some to very little street life since i will put a spool in it, mainly driven on roads to go to and from the trails. would i have to worry about damaging anything

4.10-4.11 won't have any effect on/off road.

I should have been more specific. Since you won't be using 4we on pavement. But either way you're good.

I'd assume you'd be fine since you prolly won't be driving in 4wd at high speeds.

Even in 4wd it won't have any effect

Why 4.10's? Dont those come standard in the xj D44? IF your planning of anything bigger in terms of rubber anytime in the future you might as well go with 4.56's or deeper

Gee oh Dee

Only on 4 cylinder XJs. And 4.10s are good gears, I run them.

33's and bigger I would go with 4.56's now.

Why won't these gears have any effect on/off road
