Upgrade your 2008-2023 Peterbilt 389 truck with Kelderman’s all-new Front Leaf Air Suspension System. This kit is meticulously designed to surpass the limitations of the factory leaf spring option. This kit will have multiple shock options available for you to choose from. An introductory shock option will be the ‘Gabriel Fleet’ option. The premium shock option comes in the form of a Kelderman-Raptor 2.0 piggyback adjustable shock. This top of the line shock option features a billet aluminum construciton with black anodizing for a durable finish and show-quality looks.
With the supplied height control valves, you can tap into your truck’s existing air supply, allowing the Kelderman suspension to automatically inflate/deflate as needed to maintain the proper ride height. This ensures that you will keep the air suspension at the optimum height for the best possible ride quality. A dump valve setup is also included allowing you to temporarily lower the air suspension to 4″ below the ride height setting.
The complete kit includes new leaf springs, industrial-strength airbags, airbag mounts, air line, fittings, and hardware for installation. Choose from the two possible shock options to complete the kit. Our steel parts are available in a durable powder coat finish to withstand the road conditions ahead. Take control of your ride quality today with the Kelderman Front Air Leaf Suspension for your Peterbilt!
