EZ 990 Helper Spring

The HELLWIG EZ 990 Helper Spring is an essential suspension upgrade designed to manage heavy loads and prevent rear-end sag in work-ready pickups. Owners of full-size trucks often encounter stability issues when towing trailers or carrying maximum payloads, which can compromise steering control and braking efficiency. By integrating this add-a-leaf system, drivers can maintain a level ride height and improve overall vehicle handling under demanding conditions. This kit provides a cost-effective solution for those looking to enhance their vehicle's load-carrying capacity without sacrificing daily drivability.

Engineering-wise, this kit utilizes high-quality steel construction finished with a durable silver powder coat to resist corrosion and road debris. The HELLWIG EZ 990 Helper Spring works by increasing the rate of the rear leaf pack, providing progressive support that engages more firmly as the load increases. This design ensures that the vehicle retains a comfortable ride while empty, yet offers the necessary stiffness to prevent bottoming out during heavy-duty hauling. The precision-bent leaves are manufactured to strict tolerances to ensure consistent performance and long-term reliability on the road.

Specifically tailored for the 2009-2014 Ford Fullsize Truck, the HELLWIG EZ 990 Helper Spring installs onto the rear suspension to provide immediate improvements in towing stability. This kit is intended for vehicles at stock height and serves as a direct-fit enhancement for fleet operators and weekend towers alike. Proper installation helps reduce body roll and improves the lifespan of the factory leaf springs by distributing stress more evenly across the suspension architecture. Whether you are hauling construction materials or a camper, this helper spring kit ensures your truck remains level and planted.
