Switching from 35s to 33s
 
1 Attachment(s)
Hey, just bought a 2000 tj sport 6 cyl, automatic. It has 35 inch tires with a 4 inch lift. I don't think it is regeared and was wondering if anyone had any thoughts if I should trade up with my friend who has 33s. Just trying to weigh the pros and cons.

It really is up to you, but I would trade em. Especially if youre not set up to run 35's (brakes, steering, axles, gears, etc) then that would be the right choice IMO.

I agree... if not set up for it completely... going to 33's will save you some grief later on.... let along cash.

If u don't have 5th gear that's a good way to know if its geared right, at highway speeds are u hanging out in 4th? If so down grade to 33's because the rest of the jeep probably isn't set up for 35's.

All depends on what you want the jeep to end up like. If your plan is to continue the build, go ahead and step up and regear.If not, downsize.

Lapis's comments would apply if you had a manual.

I have an LJ with 35's and I love it.

Was it worth it? For me, absolutely - it's not a daily driver and I love the 35s on the trail. We don't do anything hardcore, so breaking stuff hasn't been a problem (so far).

Is it worth it for you to upgrade to 35's? I think it depends on what you are going to with it.

Its got the miller lite fender upgrade, that's a plus.

Sorry about my comment just reread OP automatic. Pretend I didn't say what I said.

Ek2000tj 10-22-2012 02:03 PM

Thanks for all the input. I'm pretty much a novice mechanically, does anyone know how I can tell if its regeared on an automatic? It doesn't feel too bogged down and just wondering if there's an easy way to tell. Thanks

Jack up the rear axle, turn the tire and count the number of times it takes to turn the rear drive shaft over once. I think if you have an open rear diff then you have to divide that by two. That should get you in the ball park. Standard gearing would be around 3.73...typically on an auto. Should be easy to spot if its higher or lower than that.

My 99 auto is 3.07 gears. I believe that is more common than 3.73.

If u didn't understand what he was talking about, I think there is some YouTube videos on the topic it might help if ur a novice mechanic as you say.

You're probably right. Sorry for any confusion. I think the 3.73's were more popular on the 03-06 auto trans.

Ek2000tj 10-22-2012 02:23 PM

Thanks. That helps alot

bojangles44 10-22-2012 02:55 PM

I would trade for the 33's as well

harleydragon 10-22-2012 03:12 PM

33's will give you better acceleration

my 94' has the 4.0 w/ 3spd Auto w/3:73 gears... Running 33's w/out troubles.

Not sure what years came with the automatic and 3:73 but 94' (pre-TJ) did for sure. :D
