ICON 2021-2026 Ford Bronco Rear Coilover Coil Cup Kit

The ICON Vehicle Dynamics Rear Coilover Coil Cup Kit (SKU 48201) is a precision replacement component for 2021-2026 Ford Bronco owners upgrading their ICON 2.5 Series rear coilovers from spring part number 148350 to the ICON Heavy Rate Rear Coil Spring Kit. CNC machined from 6061-T6 aluminum and black anodized, this kit supplies the correct coil seat height to restore ICON's recommended rear ride height after the spring swap.

The Right Height for the Heavy Rate Upgrade

Different production revisions of ICON's triple-rate rear Bronco coil spring have required coil seats of varying heights to land at the correct ride height. When a 2.5 Series rear coilover currently fitted with spring PN 148350 is upgraded to the ICON Heavy Rate Rear Coil Spring Kit, the original coil cup sits at the wrong height, leaving the rear end outside ICON's specified ride-height range. This kit provides the specific seat height ICON specifies for that spring combination, so the rear suspension geometry and ride height match ICON's calibrated setup.

CNC Machined 6061-T6 Aluminum Construction

The coil cup is machined from 6061-T6 aluminum, a grade chosen for its strength-to-weight ratio and dimensional stability under repeated suspension cycling. Black anodizing adds a corrosion-resistant surface layer that holds up to road grime, moisture, and the thermal cycling common in off-road use. The part is machined rather than cast or stamped, so seat-to-coil contact surfaces are consistent across the kit, a detail that matters when precise spring preload is the whole point of the upgrade.

Features

• Direct fit: designed specifically for ICON 2.5 Series Bronco rear coilovers
• CNC machined 6061-T6 aluminum: precise dimensions, consistent spring seating
• Black anodized finish: corrosion-resistant surface for off-road and weather exposure
• Correct seat height: achieves ICON-recommended rear ride height with the Heavy Rate Rear Coil Spring Kit

Who This Is For and Isn't

This kit is for 2021-2026 Ford Bronco owners who already have ICON 2.5 Series rear coilovers fitted with spring part number 148350 and are upgrading to the ICON Heavy Rate Rear Coil Spring Kit. It is the correct coil seat to achieve ICON's specified rear ride height with that spring combination.

This kit does not fit the Ford Bronco Raptor. It is not required for ICON 2.5 Series Bronco rear coilovers that are not currently equipped with spring PN 148350. The ICON 2.5 Series rear coilovers and the ICON Heavy Rate Rear Coil Spring Kit are each sold separately; this kit is not a standalone coilover or spring.

Common Questions

How do I know if my Bronco needs this coil cup kit?

This coil cup kit is only required when upgrading ICON 2.5 Series rear coilovers on a 2021-2026 Ford Bronco to the ICON Heavy Rate Rear Coil Spring Kit, and only when those coilovers are currently fitted with spring part number 148350. If the coilovers carry a different spring part number, this kit is not needed for that upgrade.

Does this kit fit the Ford Bronco Raptor?

No. The ICON Rear Coilover Coil Cup Kit (SKU 48201) does not fit the Ford Bronco Raptor. It is designed exclusively for the standard 2021-2026 Ford Bronco equipped with ICON 2.5 Series rear coilovers.

Are the coilovers or the Heavy Rate springs included?

No. This kit contains only the coil cup seats. The ICON 2.5 Series Bronco rear coilovers and the ICON Heavy Rate Rear Coil Spring Kit are each sold separately. This kit corrects the seat height between those two components; it does not replace either of them.

Why is the coil seat height important when swapping springs?

Different production revisions of ICON's triple-rate rear Bronco coil spring have required coil seats of varying heights to reach the correct ride height. Using the wrong seat height after a spring upgrade can leave the rear end outside ICON's specified ride-height range. This coil cup kit provides the seat height ICON specifies for use with the Heavy Rate Rear Coil Spring Kit on coilovers previously fitted with spring PN 148350.
