Construction & Design:

ICON’s dual rate springs are crafted from premium-grade steel, engineered to withstand the rigors of heavy-duty use and off-road abuse. The dual rate design features a progressive coil pattern that provides a softer initial spring rate for comfort and a firmer secondary rate for load support and stability. This approach reduces harshness over small bumps while preventing bottoming out under heavy loads or rough terrain.

Each spring is precision wound and heat-treated to ensure consistent performance and durability. The powder-coated finish protects against rust and corrosion, extending the lifespan of the springs even in harsh environments. ICON’s commitment to quality ensures these springs maintain their lift height and performance over time.

For best results, professional installation is recommended, especially when combined with other suspension upgrades. The kit is compatible with factory shocks and can be paired with ICON’s shock absorbers for optimized performance.
