Looking for a softer coil springs for my Quigley

[Arik]

Ride is a little bit rough (to say the least..) with the heavy duty coil springs
I'm looking to buy a softer springs without losing the original lift height

A softer spring may not help, it will allow the van to bounce off the bump stops even more. What shocks are you running?

The shocks are the original shocks
It is not the bouncing as the strike feeling when hitting a bump on the road that disturbs me

I got stiffer larger springs for my 96' Quigley and cut the bump stops by 2-2 1/2 inches.

Helped ALOT, a lot less if any BAM! on the bump stops..

Careful Cutting the bump stops will vary since the next stop where it will hit the frame,crossbeam is the diff/case (pumpkin)..

Will you sell me the old ones?
Saw on your gallery the nice work with the air lift sys, can you share the details?

We are working on a stock ride height spring. We all ready have smooth riding lift kit spring. Just because I wanted 35" tires on my van. Shocks do help but springs must be matched with a solid front Axel not a twin ibeam spring. We are hoping to f
Have springs soon.
How tall are ur spring with the weight of your van. Because we are making 4 different weight springs. So we are gathering info to find out what ride height stock springs are.

Before you start swapping springs, throw a set of Bilstein 5100s on it & see what happens.

[REF]

I second that...install bilsteins, while your at it do all 4, BIG improvement over stock. We went from stock shocks to ranchos (did not like them on the van) to bilsteins, superior by far and believe it will give you the ride improvements you are looking for. If you go with softer springs, you will end up wallowing and hitting that bump stop over small stuff.

UPDATE

I replaced to Bilsteins and still no improvement!

I realy think that the problem is the coil springs
Quigley saying that they put different coil spring on my van (4600 lb Ford # F2UZ-5310-V)

As for the bump stop, do you mean the one in the pic?

Need your help guys... can't ride like that!

Sounds like you're bottoming out on the bumpstop, looks like it too from your updated photos. You need longer springs, or stiffer springs, not softer ones. I was on my bumpstops- different platform, SMB4x4, but whenever I hit any bump, say railroad tracks on a highway, it would bottom out and jar the heck out of me. Otherwise the ride was fine.

If that's the case, I don't see what you can do but keep the axle further away from the bumpstops, which means stiffer springs and/or longer springs, or different driving. I suppose you could try other things with the shocks (double the bilsteins?)- not really sure about shocks even helping, but I've never done too much with shocks except slap them on.

The problem is you don't have much clearance, so you can't move the bumpstop. Maybe you can fit softer bumpstops to lessen the impact.

My solution was to go with Deaver leaves all around, however like I said mine is a SMB4x4, just the same problem. It raised the height a few inches, but the spine compressing bumps are gone.
