Rear Air Helper Kits

Rear air helper kits give your truck the support it needs when the factory suspension isn’t enough. Whether your build is lowered for stance, running stock ride height, or sitting on a lift, air helper springs add stability, improve towing confidence, reduce sag, and keep your truck tracking straight under load.

At Serial Killer Customs, we stock air helper kits designed to work across every setup — including trucks that most companies overlook: static-dropped and leveled-down builds. Our kits maintain usable travel, restore carrying capacity, and prevent bottoming out on lowered applications, all while delivering the same load-leveling performance expected on stock or lifted trucks.

If you haul, tow, load up the bed, or just want a smoother ride, these kits give you the adjustability and control your suspension should’ve had from the start.

Rear Air Helper Kits from Serial Killer Customs — control the load, keep the stance, and drive with confidence.
