tobycat1 about 500 for gears, well over 2g to swap in a 4.0L. I don't have that right now. Cause a good 4.0L and a new tranny aren't in my budget. plus computer and wiring, engine mounts.... etc!
02-20-2008 11:56 PM
Triple88a get a 4.0.. +100 easily
02-20-2008 10:56 PM
tobycat1 And I don't ever do rocks. I don't find it fun. Mainly mud, trails, and badass hills
02-20-2008 10:55 PM
tobycat1 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
02-20-2008 10:34 PM
debruins 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

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.

Triple88a Even though you have the same gears, the first gear on a manual is going to be different ratio than the first gear on an auto.

Me and you are kinda the opposite. I like to go real fast through muddy trails, and mud and more mud, and some tough hills. NO rocks for me

By faster you mean you can go higher mph on first before you hit redline?
02-20-2008 07:43 PM
nicolas-eric 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.
02-20-2008 07:37 PM
Triple88a With a 4 banger, i'd go with the 4.88s. 4 bangers have higher redline so..

If i ever bother messing aroudn with the gears for my d35 i'd go with 4.88 too
02-20-2008 07:25 PM
tobycat1 Thanks, I still can't decide 4.55 or 4.88
02-20-2008 07:05 PM
Triple88a I have 3.73, 35s, 4.0 5speed and on 5th gear at 65 mph i'm at ~1800rpm
02-20-2008 05:01 PM
SurfnSnow 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.

Do you wish you went 4.88? what is your top speed? what rpm at 65 mph? auto or manual? 2.5 or 4.0?

Triple88a I've got 35s 3.73 4.0 and manual.. so far its working for me. Puts me at nice low rpm with 50 mph
02-19-2008 04:04 PM
Dukes 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.
02-19-2008 02:12 PM
nicolas-eric i had 32s with 3.07 gears and auto tranny. it was ok for me.
02-19-2008 02:10 PM
richp Four cylinder or six cylinder, manual or automatic ?
I have a 2.5 in one of my 97's with 4:10's and 30's, works well but no nads on the interstate in 5th on hills.
02-19-2008 01:40 PM
bpowa those arent gears.. those are axels.. you have to find out your gear ratio. metal tab on the diff case.. i say you have 3.07 or 3.73.


I have 3.73 right now and i run 32'' I know I can run 33'' also.. just sucks a bit in acceleration.
02-19-2008 01:31 PM
Dukes my mistake, stock gears with d30 in the front, and d35 in the rear
02-19-2008 01:29 PM
Dukes It is geared d30 in the front, and a d35 in the rear
02-19-2008 01:24 PM
Scout What gears do you have right now?
02-19-2008 01:22 PM
Dukes
gears, and tires

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 ?
