A chassis manufacturer has no way of knowing what body will be placed atop its chassis, how much it will weigh, or where that weight will be placed. As a result, some motorhomes built on the Chevy/Workhorse P30/P32 chassis don't have even weight distribution, which can result in listing, harsh ride, excessive sway, porpoising, dynamic changes in toe (alignment) and accelerated tire wear. The SuperSteer® coil springs are manufactered to match the weight of your motorhome, thereby restoring correct ride height, proper suspension geometry and ride quality. With SuperSteer® coil springs, you can eliminate the use of airbags inside your coil springs. If you desire to still utitlize air bags with our springs, we have them available.
