Firestone Coil-Rite Rear Air Helper Spring Kit for 2019-2026 Ram 1500 & 1500 Classic (4130)

Fits 2019-2026 Ram 1500 and 1500 Classic models, including Big Horn, Laramie, Limited, Rebel, and TRX (see fitment table for full submodel coverage).

The Firestone Coil-Rite air helper spring kit is designed to provide additional support for vehicles with rear coil spring suspensions. By installing these durable polyurethane air springs inside your existing coil springs, you can adjust the air pressure to compensate for heavy loads, ensuring your Ram 1500 remains level and stable. This system effectively eliminates bottoming out, reduces suspension fatigue, and improves overall ride quality and braking effectiveness when towing or hauling.

This kit features individual inflation valves, allowing for precise side-to-side or front-to-rear adjustment to balance off-center loads. Most applications are no-drill, utilizing factory mounting points for a straightforward installation that typically takes 1 to 2 hours with basic hand tools.
