4 or 5 leaf springs

my jeep sits lower on the passenger side then the driver side. it is about 3/4 of a inch lower. when we get into some rough stuff the passenger tire gets into the fender. i put longer bump stops on and it didnt help. i was wondering if i put another leaf in the spring pack on the passenger side if the would help. i am running a 2.5 rancho lift, i in left shackers and a 1.5 in body lift with 33s tires.thanks for your help

I personally wouldn't mix match the springs..yours might be bent..whether I replaced them or added a spring,I would do the same thing to both sides..sounds like they need replacing...check the rear springs too..a bent rear spring can make the front unlevel too

That May make it change lanes or head for the ditch with a big dip in the road. dirt track car run a stronger spring in the right front to help make them left in the turns.

with a 2.5 spring lift, 1in shackle lift, a 1.25 body lift and extened bump stops should the tire still be getting into the fender? do i need to go to a 3.5 or 4 in spring lift. i am running 33s tires on this jeep

4" minimum for 33" tires, and that isn't going to guarantee that you wont stuff the tire into the fender.
I have 8.5 inches of lift (4 suspension, 3 body, and 1.5 shackle)with 35's and up until I went to flat fenders I could still get the tire to scrub the fender when it was flexed out.

You might try doing a TJ fender flare mod, that opens the fenders up quite a bit. Do you have a passenger when the tire is scrubbing?

I don't have any bump stops on mine. the suspension is stiff enough that they weren't needed. The only upward flex mine gets is when the tire bounces...lol.

So, you have a 2.5" spring lift...

1" shackle lift? measuring from bolt to bolt on the shackle is 6"?

And a 1.25" body lift? Never heard of that but it's possible. It actually has a lift block added in there that is 1.25"?

I don't know why you are rubbing, you should have enough total lift to clear those tires. My only thought is that the springs are getting weak...What kind of shock are you running?

Is your passenger heavier than you are? I know that sounds rude, and I meant no harm, just trying to troubleshoot the issue.

I have a buddy that goes wheelin' with me at times, im about 230lbs, and he is pushing the 400 mark, and I can tell a noticeable difference when he is in there. The springs are getting weak and starting to sag, I bet if you measured it out, the spring lift is probably down under 2 inches. Most of the arched leaf springs only have a ride life of around 3yrs. Do you know how to measure for the amount of actual lift that you have?

OK...take a measurement from the bottom of the body (at the center of the door) to the ground. A stock YJ on stock tires this measurement is 18"

Measure the true height of your tire.. not 33" but what it actually is. A stock tire for a YJ is 27".

Take the difference from your body measurement, and minus the difference from your tire measurement and this will be total lift. The take off the 1.25" of lift for the body lift, and this will be your total suspension lift.

Here is mine for an example....

My body is 34" from the ground,34-18 is 16"

My tires are 34.5" tall (35's), 34.5-27 is 7.5"

16" minus 7.5" = 8.5" total lift...

8.5" minus 3" (body lift) = 5.5" suspension lift.

and 1 step further...5.5" minus 1.5" (shackle lift) = 4" suspension lift.

i think i found the problem. doing this math i have 1" suspension lift. i think new springs are in my future...now the big problem.... what brand of springs to buy and do i go 4" or 2.5" lift again.....
