Description
The Silverado 4500/5500/6500 trucks are the long-overdue option from GM for the heavy-duty truck market. If you are looking to upgrade the factory leaf spring suspension then look no further than Kelderman’s time-tested 4-Link Rear Air Suspension System. This kit features a four-airbag design (two per side) to provide a better all-around suspension system for your work truck. Air suspension can provide you with softer ride quality and you will no longer experience the harsh rebound of a stiff leaf spring suspension. Our kit also comes with four adjustable trailing arms to allow you to center your rear axle properly within a service body, truck box, etc. These will keep the rear end in place along with an adjustable panhard bar setup that prevents side-to-side movement when going down the road. In addition to the components, the kit will include trailing arm mounts, upper and lower air bag mounting plates, rear cross member, rear sway bar, sway bar end links, axle clamps, air line, fittings, and Schrader valve inflators. This will allow you to add air to the suspension ‘manually’ like you would a truck tire. Self-leveling air control packages are available to provide your truck with an onboard air compressor, air tank, height control valves, dump valves, air dryer, and in-cab controls to allow the rear suspension to automatically adjust to weight as needed to maintain the proper ‘ride height’ or lower 3.5-4″ at the push of a button. Finally, give your Silverado the ride quality you deserve with an upgrade to a Kelderman 4-LinK Rear Air Suspension. Rear Axle Diameter Verification Required.
