gearing for the street

[DansGreyMj]

my mj is a dd as well as a wheeler but mostly street/highway i an going to run between 32s-33 and was wondering how low i should go to keep good speed and mileage, by the way its a 4.0 5spd

4.10 - 5.13

 

 

 

Unless you spend all day going 70mph+, go damn low.

 

 

 

But, it's a lot cheaper to pick up a set of 4cyl axles with 4.10s in them. Or a 4cyl front and a 8.8 rear.

4.56

 

I got 20mpg with my 4.0/AW4/4.88s/33x12.50s

 

the 5 speed has a little less overdrive, so 4.56 would be better.

 

if there's any chance you'll go to 35s just get the 4.88s now.

I agree with DC, a 4 cyl front and an 8.8, but 4:56's are nice too.

[CWLONGSHOT]

I agree....for your specs, 4:56's is what I would do...

Considering most 4.0L/5spd MJ's and XJ's came with 3.07 gears, I'd go with the 4.10 and be done. I found a Jeep D30 and an 8.8 in the junkyards, $100 each.

I'm gonna find a non-disco 30 with 410s and buy 410 thick gears for my xj 44
