Stumbled on a neat suspension device
 

Ok.... Maybe I don't hear about stuff as soon as other people, but I thought I'd share this.

Roadmaster Active Suspension. ( google it)

It improves your ride when you have leaf springs, by using a coil spring.

Has anyone heard about, if it's worth the $350.00 plus price?

It seems like a cool design, especially stiffing the side motion in a turn.

Any thoughts?
