To provide for sustained shock performance at speed through rough terrain, Stage 4 adds remote reservoirs to the ICON Coilovers. Reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade.

- TECH NOTE: Fitment testing done with ICON & OE steering components. Due to tight clearances to front coilovers, certain aftermarket steering components may not be compatible.
- TECH NOTE: Triple rate rear coils are optimized for improved suspension performance and ride quality for a near-stock weight Bronco. Their softer initial spring rates will net lower than advertised ride heights as weight is added to the rear of the vehicle. For heavier equipped Broncos, consider part number K40004TX.
- TECH NOTE: Not compatible with Bronco Raptor
