Moving to 33"s... Should I be regearing?

Well I've finally got the money to get some bigger tires, and I want to go up to 33"s. Right now my Jeep is sitting on some dinky ass stock 28" tires. The gearing is I'm assuming 3.07 (I'd check but I'm about a thousand miles away right now). Should I move up higher with 33"s going on? I'll be using it a lot on the street as well as off road. How much of a power loss should I expect if I don't regear? Also, what should I expect to pay?

Thanks for any tips guys.

With 33's I would recommend 4.56's. Check around for pricing. Would guess you could expect around maybe $500 for front and rear with two master install kits. (not including installation)

When I went to 33's I wanted 4.56's, but the local 4 Wheel Parts store convinced me to do 4.10's. They worked ok, but I think I would have preferred the 4.56's in the long run...especially since I moved to 35's just over a year later.

i would definitely regear if you can.

you don't have to though. if you can't, you'll be fine.

it will depend on your setup (engine and transmission) as to which gear ratio to run. if your regearing a dana 35 then i would at least throw some chromolly shafts in. JMO

33" tire size is where the cost of regearing starts to make sense. Typical costs to regear are $1100-$1200 or so. But what ratio will make sense for you depends on which engine you have and which transmission you have. More info please!

I've got the 2.5L, as far as transmission goes I'm not sure.

Surely you know if you have an automatic or manual transmission.

??

That cost count the price of hiring somebody? From what I could tell (by a quick search @ quadratec), gears themselves are ~ $160/ea and the master install kits are ~ $100/ea.

Since very few Jeepers have the ability or desire to install their own R&P gearsets, that $1100-$1200 price I gave to regear includes normal shop labor, everything complete.

That makes it simple, 4.88 is the appropriate ratio for 33" tires, 2.5L four-banger, and 5-speed transmission. Because you have the four-banger, don't even consider 4.56 which is commonly recommended for those with the 4.0L engine and 33" tires.
