^ Might want to measure those and/or get more information, the arch looks preeetty close to the stock leaf packs

yea, I just sent him an email asking for the brand and a few other questions about them.

So I have the zone 3 inch full lift kit for my 1990 4.0 I'm going to start on the front first with coils and shocks, still waiting on the IRO. leafspring shackle's.
Plan on measuring now to see how much Lift I actually have with stock springs and a 3 inch coil spacer. Rear is the same stocks Springs with aluminum blocks.
This is what I have now.
Anybody running the zone 3 inch full lift kit now? I have a pair of stock Crown replacement isolators is that all I need for the coils on the front? How much Lift is the stock isolator going to give me ??don't want to go more than 4"

Someone said to expect more than 3"s from zone 3" coils.
I have stock bumpers now.

Goal right now is 3/12" front and back..
IRO. Lift spring shackles I have coming are 0" stock hight to 75" lift .
Opinions and any help is much appreciated. thank you!

askingxforxit

My zone 3" kit have me about 3.5

That's good to know, so if I stack two stock isolators together I'd probably be over 31/2"?
I know every jeep is different.
Are the crown stock coil isolators even stackable or safe?

SteveMongr

One is required, two can be stacked, no more than two. 5/8" each.

How do you like the IRO. shackles Stevemongr? God dang, can't wait till mine get here! Check what I'm working with now not fun!! It's like riding in a rickshaw... so funny..

So i want to lift my jeep in the near future, but cant afford it until hours pick up at work again. in the meantime, I at least want to get some new shocks on it. Can i get some shocks now that will work for stock height and lifted or no? I am just looking at a little 3 inch lift.

look at the ALUMINUM blocks in the rear. Those crack, smash and fall out.

This is how kids did it back in the 80's as long as it looked cool nobody cared. My neighbors probably think I'm paranoid For the past 2years, every morning as a ritual coffee in hand, fist thing I do is look underneath my truck checking those springs...

SatiricalHen

well Cherokee leaf springs can't handle the axle wrap caused by the extra leverage of block.

Basslicks

No. Sorry man, you may view 3" of lift as "a little 3 inch lift", but it's actually a pretty major difference in terms of suspension geometry... and shock travel. The full range of motion for an OEM shock is much less than the range of motion for a jeep that's been lifted 3"... for instance, say you got the OEM shocks and then lifted your jeep... the first time you flexed out, your "droop" would max your shocks out and either rip them from the body, or pull the ram out of the shock body. If you got shocks for a 3" lift but kept it stock, you would have to add bumpstop to keep the shocks from bottoming out and either punching through your floor or jamming the ram into the valve body

See what I'm getting at here? It's all part of a system. You can't buy one component of a lift and expect it to work without the rest of it.

Basslicks

Applying torque to ANY spring over axle setup with a block can cause axle wrap... that's why you see a lot of lift trucks with leaf springs rolling around with traction bars on them... it eliminates the axle wrap with a "stiff arm" that still allows "free" movement of the suspension, but doesn't allow the axle to move forward or aft outside of the natural motion of the suspension arc.

With or without the bars though, I would NEVER run an AL block... unless it was forged aluminum - to wit, is cost INeffective.

SatiricalHen

but truck leafs are thicker and more stable without traction bars versus a Cherokee. Lift blocks just aren't really good.
