ICON 2021+ Ford Bronco Heavy Rate Rear Coil Kit # 48200

ICON Vehicle Dynamics Heavy Rate Rear Coilover Spring Retrofit Kit # 48200 is designed for use on 2021-23 Ford Broncos already equipped with ICON Rear Coilovers. ICON Heavy Rate Rear Coil Springs will result in a slight positive rake when the Bronco is unloaded. Actual numbers will vary for each individual Bronco. But the ICON 4-Door Badlands (pictured on this page) is equipped with the ICON Stage 8 Suspension System with Heavy Rate Rear Coils and has a modest 1° positive rake with no extra cargo. Note that the Bronco is equipped with a 37" spare tire and an ICON Impact steel plate rear bumper. With a moderate load-out of 150 lbs. added to the rear cargo area, the Bronco squats just over a half inch, approaching a near-level rake of just 0.4°.

To simulate a heavier load-out that is more typical of overlanders and others who carry lots of extra gear, ICON loaded the Bronco up with 280 lbs. in the cargo area and 520 lbs. in the rear seat area, for a total of 800 lbs. of extra weight. This lowered the rear ride height by 2" compared to unloaded, resulting in a slight -0.4° negative rake. Heavy Rate is a perfect all-around rear coil spring for those who either keep their Broncos heavily loaded full time, or only for occasional expeditions but want to maintain the best possible performance across various load-out scenarios. The Heavy Rate Rear Coil Spring Kit is used to retrofit existing ICON Rear Coilovers to the Heavy Rate specification. The kit simply includes the replacement Heavy Rate coil springs.

KEY FEATURES:

• Increased cargo load carrying capacity with less suspension squat
• Unique ICON engineered dual rate coil spring
• Designed for full time large cargo loads

IMPORTANT INFORMATION - MUST READ

Before ordering the Heavy Rate Coil Spring Retrofit Kit, identify which coil springs your ICON coilovers were originally built with. The initial run of ICON rear coilovers (early build) will require the new design Lower Coil Cup Kit, which may be ordered separately as p/n 48201. These early coil springs will be stamped with the number 148350 as shown in the image. 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 #48201 Coil Cup Kit to install the Heavy Rate springs.
TECH NOTE: Fits ICON rear 2.5 Series coilovers ONLY. Not compatible with OE, ICON EXP Series, or other aftermarket Bronco rear coilovers.
TECH NOTE: Sold as a pair
