High-Rate Suspension Tuning with Howe Spring Helpers

When your track setup requires a firmer response, the Howe Racing 20lb hard coil spring helper is the ideal solution. Engineered for 5 to 5.5 inch diameter springs, this high-density polyurethane insert provides a significant increase in spring rate, helping to stabilize your vehicle during aggressive cornering and high-load maneuvers. These helpers are specifically designed to reduce suspension travel and minimize body roll, giving you the confidence to push your car to its limits.

Technical Specifications

  • Rate: 20lb (Hard)
  • Spring Compatibility: 5 to 5.5 inch diameter
  • Height: 1.25 inches
  • Material: High-density polyurethane
  • Finish: Natural
  • Quantity: Sold individually

The hard-compound construction ensures that these helpers maintain their shape under extreme pressure, providing a consistent and predictable feel throughout the entire suspension stroke. The 1.25-inch height is optimized for easy integration into your existing coil-over or standard spring setup. By effectively stiffening the spring rate, you can achieve a more responsive turn-in and better overall chassis balance. These durable inserts are built for the rigors of racing, resisting heat and mechanical wear better than traditional rubber alternatives. Whether you are adjusting for a specific track surface or compensating for a change in vehicle weight, these Howe Racing components offer the precision you demand.
