Hellwig EZ-990 Helper Spring Kit Heavy Duty Powder Coated Leaf Assist

Description

Product Overview

The Hellwig EZ-990 Helper Spring Kit is engineered to deliver a robust, yet adaptable, leaf‑spring assistance system for light trucks and sport‑utility vehicles. Constructed from heat‑treated ASTM 5160 alloy steel, each spring is machined to precise tolerances and then finished with a durable powder‑coated coating that resists corrosion and wear in harsh environments. The kit includes two identical helper springs, a full set of heavy‑duty U‑bolts, mounting brackets, and detailed installation instructions, ensuring a complete solution right out of the box.

Designed to sit atop the factory leaf‑spring pack, the EZ‑990 works in concert with the existing suspension to increase the effective spring rate, reducing sag under load and improving overall ride quality. The springs are rated for a maximum load capacity of 2,000 lb, making them ideal for light towing, cargo hauling, and passenger weight distribution. With a compact footprint of 43 × 2 × 7 inches and a weight of 34 lb per spring, the kit adds minimal unsprung weight while providing maximum benefit.

Installation is straightforward: the springs bolt directly to the existing leaf‑spring eye brackets using the supplied U‑bolts, which are fully adjustable to fine‑tune the preload. No special tools or modifications are required beyond a basic socket set and torque wrench. The powder‑coated finish not only enhances aesthetics but also protects the springs from road salt, moisture, and UV exposure, extending service life well beyond typical aftermarket accessories.

Usage

The EZ‑990 Helper Spring Kit excels in real‑world scenarios where additional rear‑axle support is needed. Owners of compact pickups, midsize trucks, and crossover SUVs will notice a marked improvement when loading roof racks, towing small trailers, or carrying heavy cargo. The kit’s adjustable U‑bolts allow owners to set the spring preload for specific load conditions, providing a customizable experience that adapts to seasonal changes or varying payloads.

Because the springs are mounted on top of the existing leaf‑spring assembly, they do not interfere with the vehicle’s original geometry, preserving steering feel and handling characteristics. The kit is particularly beneficial for vehicles that frequently travel on uneven or unpaved roads, as the added spring support helps maintain tire contact and reduces the likelihood of bottoming out during aggressive braking or cornering.

In addition to load‑carrying applications, the EZ‑990 can improve ride comfort during everyday driving. By reducing the amount of sag that occurs when the vehicle is empty, the springs help keep the chassis level, resulting in a smoother ride and less strain on suspension bushings. This dual benefit of performance and comfort makes the kit a versatile upgrade for a wide range of drivers.

FAQ

What vehicles are compatible with the EZ‑990 Helper Spring Kit?

The kit is designed for a broad range of small trucks and SUVs that use leaf‑spring rear suspensions. It fits most models from major manufacturers, including Chevrolet, Ford, Dodge, and Toyota, provided the stock leaf‑spring eye brackets are present. For a specific vehicle fit list, consult the product manual or contact our support team with your VIN.

How much weight can the kit support?

Each spring in the EZ‑990 kit is rated for a maximum load of 2,000 lb, which translates to a total additional capacity of 4,000 lb when both springs are installed. This rating is ideal for light towing, roof‑rack loads, and cargo that falls within the typical payload limits of midsize trucks and SUVs. Exceeding the rated capacity may affect performance and is not recommended.

Can the springs be adjusted after installation?

Yes. The included heavy‑duty U‑bolts are fully adjustable, allowing you to change the spring preload without removing the springs. By loosening the bolts, repositioning the springs, and retightening to the specified torque, you can adapt the system to different load scenarios, such as seasonal cargo changes or varying towing requirements.

What tools are needed for installation?

Installation requires a standard socket set, a torque wrench, and basic hand tools such as pliers and a screwdriver. No specialized equipment or lifting devices are necessary, as the springs are designed to be bolted on while the vehicle is on the ground. Detailed step‑by‑step instructions are included in the kit packaging.

Is there a warranty on the EZ‑990 Helper Spring Kit?

Hellwig provides a limited warranty that covers material defects for a period of one year from the date of purchase. The warranty does not cover damage caused by improper installation, misuse, or modifications. For warranty claims, retain your purchase receipt and contact our customer service department with the product serial number.
