Anyone have this setup? If so, what is it like?

 

if I am not mistaken the 2.5 manuals had 4.10 gears so you should be just fine.

 

Thanks Mike

 

Yeah i had to recheck the service manual a xj with 2.5's came stock with 4.10 gears the 4.0L with manual tranny came with only 3.07's

so you should be good.

 

Mines a dog with 235/75's (around 29" diameter). I noticed a slight difference going from 225/75's to the 235's. I can only imagine that it would get worse with 31's. Its fine offroad, but kind of a bummer being the "slow jerk" when taking off from a light in traffic.

 

I know its not an XJ, but my 1990 Ranger has the 2.3 liter motor, 5 speed, 4x4, 4.10s and HAD 31s. Around town its a blast. First gear is deep enought to manage just fine. But on the highway its not as much fun, I can get to 80 with a bit of trouble, but forget trying to pass. 5th gear is all but useless. Although, when I using it to commute (100 miles a day round trip), I WAS getting 26-28 MPG... Pretty good considering the lift AND the big baja type front fenders.

Since it is a trail oriented rig now though, I slipped 33s on it, but haven't driven it lately (dead slave cylinder). If I was smart, during my D30 swap, I SHOULD go 4.88s...

 

ive got one with the 2.5l and manual, i love it off road, its got 33s and does fine so far with 6in. homade lift, its a little boggish in 4th and 5th so far but needs head work, they do all have 4.10's and are great in 4low
