We just "softened" up my cousins rear leafs. 1 bobcat on a single axle trailer on the front, hook it to the receiver and let er sit for a day or 2 with bout 4k on the rear leafs. His at like 2" high in the rear now only .5" and rides way nice. The hitch started out 2 feet off the ground, when we but the bobcat on u couldnt put ur foot under the hitch!

They are officially out of R and D staged and into production. We have another laser order placed. Turn around time will be much quicker now.

No, I'm saying he can get a softer ride by adjusting the tire pressure for ride comfort.

Probably not the answer he was looking for, but it is Pro Comp afterall.

my tire press is at 35 psi cold... so its not the tire pressure.. i am not complaining about stiff suspension.. i drove C5 vette on streets with T1 suspension for years lol so i know bumpy... but XJ will bump me to another area code

Too much tire pressure can make for a very harsh ride.
Stock 225 tires calls for 33PSI, on my 98 XJ.
For bigger tires, I go with less PSI..
I put new spring on my old Plymouth, it took a couple months
before the car road good...

i run ~32 psi in my 33's and when i had 32's. i have the same tread wear as when i had 225's...i found i didn't need to deflate my tires just because they were bigger. i've got more square inches of surface but the pressure acting on those square inches is the same. this may be different for others with different style/size of tire though...dunno.

its still too high. i drive ~28psi to get an even contact patch on the road. and like everyone else said, wait a while. toss some junk in the back. my first lift 6 years ago (rusty's 3" full leaf pack) sat at 6.5" the first few days. eventually it settled down and softened up.

draw a straight line of chalk across the tire tread (inside to out) and go for a drive. if it is only wearing in the center, lower your tire pressure until the line wears out evenly.
