I want to either put a 4.5 inch lift with 32s on my XJ or put a 4.5 inch lift with a one inch coil spacers and 33s. I would rather put the 5.5 total lift and the 33s, but price is a factor. The wheels i have, have a 4 inch backspacing. I would like to know what other mods i would have to do to put on 33s. Any suggestions or recommendations would help.

 

regear

You haven't filled out your profile yet, so I don't know what your current setup is.

Depending on if you have an automatic or a stick, you probably have 3.55 or 3.07 gears stock. Going from a 28.5 stock tire to a 32-33 your going to notice a significant power loss. 3.55 might be manageable with an auto if the torque converter makes up the slack, I'm not sure mines a stick.

From what I've seen most people that go to a 32-33" tire go up(down really) to 4.10 or 4.56 gears to make up for the power loss.

Play with this link. Go down to Find RPM.
MPH = 60
Transfer Case = 1
Transmission ratio =1 (stick is .79 for 5th gear, not sure about auto)
Tire Diameter = 33

Then play around with 3.07, 3.55, 4.10, 4.56 for axle ratio and see what effect it has on the RPM.

 

ya i have a 3.5" lift with 2" pucks & 29.5" tires, but i'm going to pick up my new 33/12.50R15 tsl swampers tomorrow & was wondering the same thing! great link thanks!!!
i cut my fenders already to make room cause with 29.5's i wasnt far from rubbing so with 33's & no cutting your bound to carve grooves in the new tires!

 

its an automatic

 

if you go 5.5" you might want to go with a SYE or a t-case drop, which ever you prefer and id go longer brake lines also

 

do i need fender flares?

 

i really want to do the 5.5 and 33s but what do i need to do inorder to get that. (flares, SYE, brake lines, backspacing on wheels,)???

 

you dont need new fender flares, try a transfer case drop kit when you go that high, them if there is still vibes do the SYE, def extend your brake lines, if you can get some after market wheels with more backspacing

 

x2 on trimming the fenders unless you have laws against them just check before you do anything. for sure get longer brake lines and like mobilecherokee said try the t-case drop before you spend the money on the SYE. and on the wheels id look into wider rims probably 10" wide with the right backspacing

 

the wheels i was gonna get have a 4" backspacing. How much is a t-case drop kit?

 

you can make some out of 1 inch square tubing, but they are usually $40-$50

 

Don't do a tcase drop unless you have to. Much of the point in the lift is to get more clearance under the middle. SYE is the way to go.

 

2500 is my total limit for everything im gonna do. my lift is 700, tires 765, wheels 180, lift installation 450, (then if i did do the one inch coil spacers it would a a few hundred, i would also then need fender flares and SYE) So i think im just gonna go with the 4.5 and 32s or 33s?
