I own a 05' wrangler. Since I've had it I put a 2 inch spacer lift. 31 x 10 BF goodrich AT. Cool air intake, and throttle body spacer. I would like to put either 32, or 33 inch all terrain tires on next. Will the stock gears keep up with the incresed tire size, or will it be too much ?
In regarding my thread. I have a 05' wrangler x. 4.0 litre 6 speed manual transmission. 2 inch body lift. 31 x 10 BF good rich AT. throttle body spacer. cool air intake. geared at 3.07. d30 in the front, and d35 in the rear.
If I go to 35's then yeah, 4:88's would be better but I don;t think I'll make the jump to 35's anytime soon and then if I went any larger it'd be to 37's (with d60's). At 65mph, rpm's are around 2k, in an automatic 4.0.
i have a 4spd auto tranny and 4.56 gears. at 65 mph i have a bit over 2000 rpm.
with the 6spd manual tranny without a torque converter i would have choosen 4.88 gears. a manual is faster at idle speed with the same gears in 1st gear IMO and that would be a disadvantage off the road.
I guess you have to decide what direction you want to go with in terms of your rig. So far for rock crawling, the 4:56's, 33's, and lockers have been a really good combo for me. But the question you might want to figure out is what is the final tire size you want on your rig? Will it be a mix of dd and trail rig or more dd with not that much wheelin'? Once you figure that out it'll give you a better idea of what you will need.
I agree somewhat with what surfnsnow is saying, but i dont think you want to go any bigger on the dana 35, if you do want to go bigger thant 33's then you'll want a new axle so then you can easily regear then so think about now, do you prefer top end speed on the highway, or do you do city and prefer acceleration from a stoplight or stopsign, do you prefer rocks or mud
Ok, here is some more info for your opinions.
33" max tires on this engine
need good accel, but also need to be able to drive at 70 on freeway
currently I can go over 70 but only in 2nd gear
my 3rd gear is useless right now, max 3000rpm in 3rd gear with pedal to the floor
also need better gas mileage, but that is going to happen no matter what gears i get
