Arrow Lift kits!

This is just driving me crazy specially that everyone advice you something different from the other, I have 1999 Jeep TJ and planning to install 33/12.5/15 tires.

A friend of mine who has similar jeep model told me 2" spacer lift kit with 1" body lift should be more than enough.

I spoke to our local jeep retail and the guy said I need at least 3.5" lift kit to fit that size of tires.

Im a bit confused I would really love to go with 2" spacer lift kit and 1" body kit only, do you think that will be enough ?

Also, which one should I install fist, tires or lift kit first ?

This is a pic of my jeep in case it helps

Thank you!

I run 33" tires with a BDS 3" Suspension Lift. You would be fine running 33" tires with 3" of total lift. You would have to do the lift first and then do the tires.

2" spacers with 1" body lift is adequate for the tires you described. I know from first hand experience. Do you plan to purchase new wheels?

2 in spacers and 1 inch body lift will fit 33s fine as long as you get rims with enough backspacing and width for the 12.5 wide tires or wheel spacers. Ive seen that set up on here a few times and may install it on my neighbors wrangler for him as well. Good way to fit 33s on a budget. Just make sure to get some new shocks for a 2 in lift and correct bumpstop extensions.
And do the lift first or else the tires wont fit

With 33" tires you need a lift kit before the tires or they won't fit.

With stock fenders, a 2" lift and 1" body lift would be the bare minimum. You would need wheel spacers or new rims with proper back spacing so you don't rub on turns. I wouldn't do any 4wheeling with it like that though because if lack of room for flex...

The proper way would be to do a 3.5" suspension lift with either a SYE and DC driveshaft with adjustable control arms or a Transfer Case Drop.

Either way when you go to 33" tires you will lose lots of power, so a Regear is suggested. What engine/transmission/rear axle do you have? I ask about the axle because 33" is the max tire size for a Dana 35, even 31" tires can be hit or miss.

No, I will buy used ones "BF Goodrich Mud Terrain tires 33x12.5 R15" but they have over 70% thread left on them.

Thank you!
If you are still running the original shocks, they are probably due for replacement too. This kit is a very popular and inexpensive way to run 33's as it includes everything you need (mml, bumpstops, links, etc).

When I purchased my 99 Sport, i had a 2" spacer lift on it with 33" tires. It was fine on pavement and pretty good offroad - but there was not much room for tire travel. If you are going to do much off road, you likely will want to do the 1" body lift, or just purchase a 3" lift to give yourself a little more tire travel.

Just my $0.02

Im still wondering about the engine, trans, axles and gears?

It was already asked earlier and I didnt see an answer. Have you thought about the loss in perforance due to the change in tire size?

Oh im sorry, It is 2.5L and 4 cylinder, Manual transmission and dont have much details about axles and gears..
I haven't really thought about the loss in performance, is it going to be very noticeable?.. I know the fuel cost will go up.

You will see a pretty big loss in performance with the 2.5L. At least you have the manual which will help a little bit. I would figure out what gears you have and would plan on a regear. It would help lessen the stress on the trans and engine, when running 33's.

Oh crap!!!, I do have 5 gears and stock axles.. so maybe i will go back to the first plan which is installing 31x10.5x15

am i going to loss performance the same thing with 31" tires ?

No not like you would see with the 33's. You would be ok with your current setup and 31's. My dad has a 99 TJ SE with 31's. He doesnt really do any highway driving but it will still run 65 pretty easy. Mainly slow crusing, driving and some off roading. Does pretty good in these areas. Especially cause he can use 4LO if he needs.

oh boy!, I run over 80 mph now with my current stock tires.. I can imagine i wont be able to run that with 33's, they look pretty though..

what if I installed 33's along with the lift kit and all that, and when winter comes I put back my stock tires, will the car be ok - i mean back to normal performance ??

thanks alot guys and sorry for asking too many questions!

You can never ask to many questions. For the most part yes. There will be a little extra wind resistance with the lift, not that Jeeps are very aerodynamic to begin with. Also it will probably look a little funny with 3" of lift and stock tires, but it could be done.

Lastly, You have to remember that the engineers who designed the jeeps went through countless hours testing and calculating the stresses on the drivetrain. There is a reason why they chose the gearing and tires based off of the engine and trans. Running larger tires and not compensating for them by regearing the final drive can put extra stress on these components which can mean early failure.

Just something to think about when making your decision.

How wide are the tires? Height doesn't matter for back spacing.

3.75" to 4.25" is the ideal range with 4.25" being best. And it's measured by measuring the distance from the mounting surface of the wheel to the inner edge.
