Mine's got the stock 258, 36" Swampers and 4.56 gears. It runs great for off-road and city driving, but lacks top end on the highway. I cruise upwards of 3000 RPM at about 60mph.

i'd recommend 4.88 for 36s especially if we're talking swampers. 4.56 is about right for 35s, if you've got proper tranny gearing...but as said above top end is marginal.

How do you like it? What engine/trans do you have and what rpm are you running at 60mph? Right now I have Chevy V8/T18 &amp; 4.56's with 30's. I run 2850 rpm at 55mph. I just snagged some 33's with only 10k miles on them. I haven't picked them up yet as they're about 60 miles away. Will I be able to hit 60mph without the engine whinning? Thanks for the help.

Re: 36\" tires and gearing.. what works best?

I have a 258/T5. My 258 is very tired. I think I turn about 2800 rpm at 72. I thought I would eventually upgrade to 35" tires, and have heard that 4:56 with 35's may lug a little in 5th gear for me. My priortity was getting as low as possible while being able to live with the cruising rpm. - Mine isn't a daily driver, and I haul it on a trailer for trips.
Knowing what I know now, I would be kicking myself if I had done the 4:56's.

Although my jeeps performance doesn't match this table, you should be able to get the incremental difference by changing tires.

I have a T18 4 speed with a 6.32 1st gear. What does your do in 4th? I'm only going up to 33's, I've only gone 3 inches up. Thanks,

Sorry, I have no idea. The 5th makes a big difference. We are talking apples/oranges. I would think the link I gave you would give you some good info.
