ICON 2021-2023 Bronco Heavy Rate Rear Coil 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.

Features:

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

Notes:

• COIL CUP KIT #48201 MAY BE NEEDED Before ordering the Heavy Rate Coil Spring Retrofit Kit, identify which coil springs the coilovers were originally built with. The initial run of coilovers (early build) will require the new design Lower Coil Cup Kit, which may be ordered separately as p/n IVD-48201. These early coil springs will be stamped with the number 148350 as shown in the image here. It may be necessary to spin the coil spring or use a small mirror to see the part number. Coilovers that bear the number 148351 on the coil spring already have the new design lower coil cup, and do not require the IVD-48201 Coil Cup Kit to install the Heavy Rate springs.
• Fits ICON rear 2.5 Series coilovers ONLY. Not compatible with OE, ICON EXP Series, or other aftermarket Bronco rear coilovers.
• Sold as a pair
