Hey y'all. I've had my 33"s for a few months now, and I'm kinda tired of a "meh" performance my truck has. I've got a K&N FIPK, a BamaChips tuner, and a magnaflow exhaust. I'll be putting in my e-fan soon as well. I've got the 4.0L too.
1.) If I regear, whill my gas mileage drop like hell?
2.) What gears do I choose?
3.) Will I ever be able to drive on the highway without getting like 1 mpg?
highway mpg just gets worse after 75-80mph and that is with 35s.
your next choice is 4.56s from 4.10s there is nothing inbetween.
my mpg is arounf 16 most all the time but depending how i drive it can fluctuate(sp?).
the power i have now isnt too far off from stock. it works great with my 35s.
BTW: I think I've got 3.73's.
Richmond makes a 4.33 for the Ford 8.8 with a 1.626" pinion and Motive Gear makes a 4.30 gear I'm not sure what our pinion size is but I found those gears in my summit mag.
what was your factory tire size?
well if that is the case then 4.10s are perfect. most 4wd rangers 01+ have 4.10s better double check.
if you want some 4.10s i have some i will sell you cheap.
I'll check tonight...is there somewhere I can check?
the tag on the rear diff will say and hte sticker on the drivers side door.
I am getting like 13-14 MPG with 35's and 4.88 gears. I freaking love it. The 4.88's are great. After driving this i wish 5.13's would have fit.
If you think at some point down the road you might go to 35's upgrade to the 4.56's now and enjoy the torque. If no way in the future you are going to 35's and it is your daily driver and you drive alot of highway I would say its up to you. You MPG would drop to the 13-15 range and at 70-80 MPH the motor is going to be truning some RPM's.
If you have 3.73 I would most deffiently upgrade. While you are re-gearing you might as well put 4.56's in now and because later down the road you might wish you did.
My truck is a dog now with my 33's, but they are alot heavier then your average 33. I hope to swap to 4:56's before winter.
Dang, I though interco tires run large!!!
yeah they do run alittle big lol.
i say get the 4.56, i have 32s and so much torque i love it it is like night and day between the 4.10 and the 3.73 ive had them all.
i know the tag will say. i wasnt sure about the door sticker.
I never felt starved for power when I had my 33s. Hell, I could spin the tires in 2nd while rolling ~20mph if I punched it just right. That was with a 4.0, 4.10 gears, and a 5spd.
i have a 3.0 with 4.10s and 31s and I get about 16-17mpg and I can still spin the tires goin around turns but not going straight.
Quick Reply: Regear with 33's?
