It is, but its the same price as the airbagit system mentioned in the thread
Agreed - I know what you guys are after, and its a bit different to most of the customers in Aus - most of them bitched about the rear end being too soft.

If I was on a budget, I would probably remove a few of the stiffer leaves, add a Sulastic rubber spring: www.sulastic.com and add the firestone bags.

Well, I don't know.
I can tell you I have driven both types of trucks, and there is quite a difference - particularly unloaded.

 

Adrian is after something.

I don't know what it is but can taste and smell it....


I bet he's gonna make his mark....

 

Oh ****! NO!



I'm not a spy

 

For one I never said anything about triple rotors

 

Hi All, as I said earlier, I removed the standard blocks and lowest (and shortest) leaf springs and inserted 3" blocks, and upped the pressure in my firestone bags.

I have noticed that the rear suspension seems more compliant. I know the shortest leaf spring, which is about 3/4 of an inch thick, doesn't support the vehicle unless you've got max load on. But I think for lesser loads, the short leaf was acting as a 'load spreader' and spreading bump loads across virtually the entire upper leaf spring. With the lower leaf removed, the axle seems now to be able to force the upper leaves into movement for smaller bumps making the suspension more compliant and making the back seats more comfortable whilst unladen. So, for me, removal of the shortest leaves on the rear was worthwhile.

I gave it a few bursts and had to the turbo spool up to 28psi boost, no discernible hopping around or any change in the suspension dynamics under load.
