Hellwig EZ-990 Helper Spring Kit adds up to 2,000 lb Capacity

Description

Product Overview

The Hellwig EZ-990 Helper Spring Kit is engineered to provide a reliable, medium‑duty boost to the rear suspension of pickup trucks, SUVs, and light commercial vehicles. Designed to sit directly on top of the existing leaf spring pack, the kit works in concert with the stock springs to raise the level‑load rating, allowing the vehicle to carry heavier payloads without compromising ride quality. Each component is fabricated from heat‑treated ASTM 5160 alloy steel, a high‑strength material commonly used in automotive springs for its excellent fatigue resistance and durability. The steel is machined to precise tolerances, then powder‑coated and plated to protect against corrosion and wear, ensuring a long service life even in harsh environments.

Key specifications include a total weight of 19 pounds, dimensions of 43 × 3 × 8 inches, and a maximum adjustable load capacity of 2,000 lb. The kit is supplied with heavy‑duty U‑bolts, brackets, and all necessary hardware, allowing for a straightforward bolt‑on installation using common hand tools. The design incorporates a fully adjustable mounting system, enabling owners to fine‑tune the spring preload to match specific load conditions, whether hauling a trailer, transporting equipment, or simply carrying everyday cargo. The EZ‑990 model is part of Hellwig’s long‑standing reputation for quality leaf‑spring accessories, and it is backed by a robust warranty and dedicated customer support.

Usage

This helper spring kit is ideally suited for a variety of real‑world applications. Light‑duty towing, such as pulling a small boat trailer or a utility trailer, benefits from the added stability and reduced sag that the EZ‑990 provides. Commercial users who regularly load tools, parts, or equipment into the rear cargo area will notice a more level stance, which improves handling and reduces stress on the chassis. The kit also excels in off‑road scenarios where uneven terrain can cause excessive compression of the rear springs; the additional support helps maintain proper wheel alignment and tire contact, enhancing traction and safety.

Installation is designed to be user‑friendly. The bolt‑on method requires no special equipment beyond a socket set and a torque wrench. After lifting the rear of the vehicle and removing the rear wheels, the installer positions the helper springs on top of the existing leaf packs, aligns the U‑bolts with the pre‑drilled holes, and tightens them to the manufacturer‑specified torque. The adjustable nature of the U‑bolts means that the spring preload can be increased or decreased without disassembly, allowing the vehicle owner to adapt to changing load requirements over time. Whether the vehicle is used for daily commuting, weekend recreation, or professional work, the EZ‑990 provides a versatile solution that enhances payload capacity while preserving ride comfort.

FAQ

Can the EZ‑990 Helper Spring Kit be installed on any truck?

The kit is designed for a wide range of light‑to‑medium duty trucks and SUVs that use leaf‑spring rear suspensions. It fits most models that have standard leaf‑spring mounting points. However, we recommend checking the vehicle’s specifications or consulting with a Hellwig dealer to confirm compatibility before purchase.

How much weight can the kit actually support?

The EZ‑990 is rated to increase the level‑load capacity by up to 2,000 lb. This does not mean the vehicle can exceed its overall Gross Vehicle Weight Rating (GVWR); instead, the helper springs help distribute the load more evenly, reducing sag and improving handling when carrying heavy cargo within the manufacturer’s limits.

Do I need special tools to install the kit?

No special tools are required. A standard socket set, torque wrench, and basic hand tools are sufficient for the bolt‑on installation. The kit includes all necessary hardware, and the instructions provide step‑by‑step guidance to ensure a safe and correct fit.

Is the kit covered by a warranty?

Yes. Hellwig offers a limited warranty that covers any manufacturing defects in the spring steel, coating, and hardware. The warranty period and specific terms are included in the product documentation, and our customer service team is available to assist with any warranty claims.

Can I adjust the spring preload after installation?

Absolutely. The included heavy‑duty U‑bolts are fully adjustable, allowing you to increase or decrease the spring preload as your load requirements change. Adjustments can be made without removing the springs, making it easy to fine‑tune the suspension for different towing or cargo scenarios.
