Premium Rear Helper Spring Kit for Loaded Ram 1500

If you're towing a trailer, hauling heavy gear, or just want your Ram 1500 to stay level and in control under load, Firestone's Coil-Rite Rear Air Helper Spring Kit is a smart upgrade. Designed specifically for coil spring suspension systems like those found in the 2019–2024 Ram 1500, this kit adds extra support inside your factory coils without compromising your truck’s ride quality when unloaded. Unlike Firestone’s Ride-Rite system–which installs between the frame and axle on leaf-spring trucks–the Coil-Rite system is engineered for coil spring setups. The air springs are mounted inside the existing coils and deliver a variable spring rate, meaning they stiffen up as you load your truck down and soften when it’s empty. That means no more excessive squat, improved stability, and better control, all while keeping the ride smooth for passengers. If your truck feels loose or saggy with weight in the back, this kit can make a big difference.

Durable Design with Heavy-Duty Hardware

Each kit includes two polyurethane air springs, heavy-duty hardware, air lines, and separate valves for manual inflation. You can inflate both springs equally or adjust side-to-side if you’re carrying an uneven load. And because most kits are no-drill, you’re looking at about a 1-2 hour install using factory mounting locations. It’s a straightforward install you can knock out in the garage without needing to permanently modify your truck. Durability is a key part of the Coil-Rite design. The air springs are made from elastic polyurethane and are rated to perform in everything from -40F winters to scorching 180F summer heat. They’re built to last and backed by a 2-year limited warranty. If you regularly tow, haul, or carry uneven loads, this is a practical solution that helps protect your suspension, reduce tire wear, and maintain safe handling in all conditions.
