Conv Spring Helper 20#

The Conv Spring Helper 20# from HOWE is a precision coil spring assembly designed to augment factory suspension geometry and load-carrying capacity on light-duty and mid-size trucks, SUVs, and work vehicles. This helper spring addresses the common problem of sagging rear suspension under load—whether from towing, hauling, or simply carrying consistent cargo weight—while maintaining the vehicle's original ride quality and factory geometry.

The 20 lbs/inch spring rate of this HOWE helper is engineered to work in tandem with existing factory coil springs, providing supplemental support without overwhelming the suspension's dampening characteristics or ride comfort. Helper springs operate by engaging under load—they remain dormant at ride height but progressively support the primary spring as weight increases, preventing bottoming and controlling squat during acceleration or braking. The compact 5.6 x 2.5 x 5.85-inch form factor allows installation in tight spring pocket spaces, while the 0.38-pound weight keeps unsprung mass minimal, preserving suspension response and tire contact quality.

This helper spring is ideal for owners who frequently tow trailers, carry heavy payloads, or operate in conditions requiring consistent load management without a full suspension overhaul. Installation typically involves removing the existing coil spring and placing the helper spring in the coil spring pocket, ensuring a secure fit. With its durable alloy steel construction, this product is designed for long-lasting performance under demanding conditions.
