Hello all,

I am working on the suspension of my Excursion. After asking some questions here a week ago, I went ahead and bought some KYB Monomax shocks all around. I had thought the front springs were OK to use for now, but I just looked again in preparation for installing the new shocks, and saw that the front springs have a negative arch. Is this normal? It looks like the eyes are about an inch or so below the center mounting point for axle. Is this normal, or is the spring completely shot?

Thanks,
Michael

 

Both the front and back of the spring are negative? I'll have to go out and look at mine, but I want to say the back is negative and the front is not. Also, year, make, model, engine, etc. helps a great deal when diagnosing problems. Have you checked the tech folders with regard to the suspension?

I have the KYB monomax on mine and 100K miles later they are wearing pretty good, but I feel that I got quite a bit of life out of them. They didn't start getting bouncy until probably 90K.

 

The rears have a positive arch in regard to how they are installed- it arches down, as I would assume it is supposed to. The front arch up, while I assume they arch down when installed, correct? It is a 2000 Ex 6.8 with 135k on it.

It is normal, and it is why we all go to V and X code springs. Do yourself a favor and go to X code front and mod-B rears. You will never regret it. Probably the best mod you can do to your X for the money.

 

w/o digging through entire spring swap thread, how much does this lift it?

i only want about 1" lift in the front, just so i don't bottom out on big bumps, mine only sags 0.25" when measured the way the manual says to measure

 

2" front and rear, AND it goes a long way to stabilizing the X on the highway. It is LARGE part of the "wander" cure.

 

 

have to measure the garage door, plus i will be be putting 33's on it, might not fit with a 2" lift...

 

 

Thanks for the numbers- my rear is 24", front is right around 22 7/8" or so- seems like the springs are in good shape. Still want to do the spring swap, when I can.
