Gears on 4 cyl

Looking at a 1998 TJ 4 cyl that is running a 4" lift and 33" tires. It has 4.56 gears. I know 4.88 may be preferable, but would this setup be OK for a weekend cruiser around town and occasional highway use?

Also, the Jeep has 118,000 miles on it but appears to be in good shape. I know the 4.0 is considered bulletproof, but what kind of life should I expect out of the 4 cyl? And how expensive would it be to rebuild at some point?

Thanks so much.

The 4 cyl and just as reliable as the 4.0. It's just a de-stroked 4.0 block with 2 cyl removed from the middle. 4.56 gears will be fine.

ive put my 4cyl through hell and its still kicking strong as ever. in my opinion its a pretty bulletproof motor. mine only has about 120,000 on it but ive seen them with 200,000 and up

OK, that's great to hear. Thanks for the quick feedback. Assuming everything works as intended, do you see any reason why it couldn't be driven from El Paso to St Louis (about 1100 miles)? I am working in El Paso until the end of the month and will have to drive whatever I buy home ...

I am running the 4cyl couldn't be happier. JP magazine indicated that 300,000 is not unheard of. It's a KISS motor. (keep it simple stupid) and it runs great forever.

Life is what happens ... when you have something else planned.

It's a manual transmission. I'm glad to hear people are happy with the 4. I owned a 2002 Sport a few years ago, sold it, and have missed the heck out of it since. I drive a Jetta on my commute but want something fun for summer and bad winter weather.

hi all

drove to florida 1200 one way several times, i dont see why not, other then gas mileage, seats are somewhat comfortable, road noise is probably going to be your common complant. just make sure you do thurough fliud and tuneup etc etc.......

4:56 gears and 33's won't be too bad. When I bought mine it had 4:10 gears and 33's and sucked, now it has 4:88 gears and 35's and it is a lot better. 4:88's and 33's would be the best combo, but I got a deal in the 35's and I can't complain too much.

imo 4.10s with the 4cyl and 33s is tolerable. You should be just fine with 4.56s.
