Kelderman 3’’ 4-Link Air Suspension Kits are designed to raise the level of performance of your Dodge truck to the next level. These kits provide the best possible ride quality not found on ordinary lifted trucks. Kelderman 4-Link Air Suspensions are available in front and rear kits. The front kit adds more clearance to your truck for bigger tires while the rear replaces the leaf springs with air bags to upgrade the suspension features. Kelderman Air Suspension Kits allow you to haul heavier loads that are previously not possible with stock. These kits are also upgradeable with Kelderman’s Air Control accessories and they come complete with premium American-made components.
