Product Description

The Kelderman 2-Stage Rear Air Suspension System for the E-350/450 Cutaway Chassis has been used in numerous markets. This chassis is extremely popular in the shuttle bus & RV markets which have been very impressed at the 2-Stage Rear and it's effectiveness at improving the ride quality of the vehicle. If you have passengers or equipment bouncing around at the back of your chassis, the 2-Stage Rear can make sure all of your passengers are much happier at the end of your trips. This chassis was designed primarily for heavy duty, commercial applications leaving it with sufficient weight ratings and undesirable leaf spring suspension ride. Air suspension has been used in commercial applications for many years and has been very effective at improving the road manners of all kinds of vehicles. Kelderman's unique 2-Stage Air Suspension framework accomplishes an improved ride quality by 'floating' the existing leaf spring suspension. This is a design that we use in vehicles ranging from 3/4 ton pickup trucks
all the way up to larger, Class 6 & 7 commercial trucks with great results. The leaf spring shackle hanger/mount is removed from the frame and the air suspension system provides an additional 3-4" of suspension travel for the vehicle. This allows you to ride on the air suspension so the bumps in the road are absorbed by the air suspension before being transferred onto the leaf springs. With the leaf springs being retained, you still have the same towing/payload capacities as before...just an improved ride quality. Kits are available in our 'manual fill' air control system for $2,150 or with an electronic self-leveling system for $3500. This allows you to focus on driving and other tasks rather than spending time on gauges, switches, or other components to ensure proper operation. It also eliminates driver training in commercial applications. All your driver has to do is turn the key and GO! Take control of your fleet with a Kelderman 2-Stage Rear Air Suspension today!
