Firestone Coil-Rite Replacement Bellow - Air Helper Spring Kit - Rear 4.38x11 (.125 Thk)(W237606133)

Made from durable, elastic polyurethane with a wall thickness of 0.125 inches, these Firestone Coil-Rite air helper springs are built to handle a wide range of temperatures, from -40°F to 180°F. They are designed to fit inside your existing coil springs, effectively creating a variable spring rate. This means you can adjust the air pressure, much like inflating a tire, to fine-tune your suspension for different loads and road conditions. This adjustability helps level your vehicle, which can lead to more effective braking and better handling, especially when you're carrying heavy cargo or dealing with rough roads. By supporting between 500 to 1000 lbs per set, these springs can reduce suspension fatigue and prevent bottoming out, contributing to a smoother and more stable ride.

These air helper springs are a popular choice for Ram 1500 owners looking to enhance their truck's capability. The ability to adjust the spring rate on the fly allows you to optimize your ride comfort and load-carrying capacity without permanent modifications. Installation is straightforward, as they are designed to work with your factory coil springs and often require no drilling.
