im eventually gonna run 33's and awanna regear my axles. I was thinking of usind either 4.56 or 4.10. which is better for a daily driver. i live in hesperia so i have to drive up Cajon summit(15fwy towards Vegas)elevation 4300 ft. what would be the rpm's at 65 mph on a straigh hwy with 4.10 gears and 4.56 gears? would the gas maileage suffer a lot? right now i have 3.55 gears and running 31's with a 3" lift and average about 2100 rpms around 70 in overdrive. most of my driving is freeway anyway.:wave:

Wether you live on flat land or in the mountians, 4.56 would be the best with 33's. Leaves improvement toward 35" down the road.

thats wut i figured, thanx
 
i went 456 with 33"s. i am very pleased but almost wish i'd gone with 4.88's for crawling.

don't have a second thought about the 4.10's......go with the 4.56's !!!!!!!

yeah 4.56 is the way im going. how's the acceleration with that low of a gear and large of a tire?

With 33's and 4.56 at freeway speed...and as I've clocked it from a friend in a honda following me, at 65 my speedo reads 72 and is running at just a hair over 2500 rpm.

gas milage isnt to good is it? im not expecting to have stock mpg but somewhat reasonable, maybe 14-15 mpg hwy

Gained 1-3 mpg highway, depending on how heavy my foot was. You should get around stock, and better than what you are getting now.

man that sounds good, i thought you would loose mpg's due to higher rpms.

Less stress on the engine trying to rotate tall tires with high(numericly lower) gears. This is with an AX15 btw.

oh true, i believe i have the aw4, i have the 98 sport 4L 6 With overdrive
 
Actually, I think I'm getting anywhere from 12-17 miles per gallon...hard to say since my speedo is still slightly off. but then again, I do mostly city driving. I will say, with the bigger tires, it becomes a lot more sensitive to your right foot. you drive like a granny and you'll do ok; you drive like you're in a sports car, expect single digits.

yeah thats wut i figure, im real soft with the pedal cuz of gas prices, sad huh? when my mom drives, omg she has a heavy foot, i need an sye and you could feel the vibrations real bad, but ill have that sye taken care of very soon.
 
Your milegae should be real close to stock. I got 17 average MPG for the whole trip to and from Moab last year....towing a 1500lb trailer. That included over a hundred miles in the dirt. I would say my normal is about 14 town/17 highway. If I drive slow (like when I have a trailer) and keep it on the highway, I can still crack the 20mpg mark. Yours should be no different, maybe even better with only 33's.
