Would you be interested in higher-rate torsion bars?

Edit: Thanks to the efforts here we now have an option from Sway-A-Way for our AWD vans: Would you be interested in higher-rate torsion bars? --AstroWill

Hello all, I'm in the midst of some upgrades on my lifted van and I wanted to get a sense of how many other people might also be interested in some upgrade parts.

For most of us with lifted AWD vans, the only real front suspension adjustment we've been able to make thus far is to the pre-load on the torsion bars; either via the stock adjusters, or with re-indexed keys that add additional preload. I would like to have the option to also use a higher spring rate on the torsion bars. With my pop-top conversion and camper additions, my van is already heavier than many folks. In particular, I have been hesitant to add an aftermarket bumper and winch to my van because of the additional weight that would still be borne on the OEM bars.

I am working with a company that manufactures aftermarket torsion bars for offroad and race use. They already produce a line of upgraded torsion bars for other GM trucks, Hummers, Suburbans, etc. These bars range from 15% up to 30% stiffer than stock. I am early in the process with them, but it sounds like they may be able to produce similarly uprated bars for the Astro/Safari platform.

I know that demand will depend greatly on price (which I do not yet have), but it may help things along to know if anyone here would be interested in a pair of these?

There are a lot of things to work out, but I believe such bars should provide a mild torsion bar lift over stock while using the OEM keys, in addition to being a better option for those of us running with greater weight over the front axle.

What say you?
