# ICON 21-23 Ford Bronco Rear Heavy Rate Coil Spring Kit

The ICON Vehicle Dynamics Heavy Rate Rear Coil Spring Kit is a dual rate coil spring kit that provides extra weight capacity for those who frequently load out the rear of their Broncos with extra gear and equipment while maintaining excellent on- and off-road performance characteristics. The Heavy Rate Coil Spring Kit simply includes the replacement Heavy Rate coil springs used to retrofit existing ICON Rear Coilovers to the Heavy Rate specification. This Heavy Rate Coil Spring Kit is a perfect all-around rear coil spring for those who either keep their Broncos heavily loaded full time, or only for occasional expeditions yet want to maintain the best possible performance across various load-out scenarios with taller ride heights under load compared to the standard ICON triple rate Bronco rear coil springs.

-   Unique ICON engineered dual rate coil spring guaranteed for life against sagging and breaking
-   Semi-gloss black powder coat finish for excellent corrosion resistance
-   Increased cargo load carrying capacity with less suspension squat
-   Retrofits onto existing ICON Bronco rear coilovers
-   Designed for full time large cargo loads
