PRODUCT OVERVIEW:
This 4.5" System for the 2011-Current Ford Super Duty is one the best riding suspension systems ICON has ever developed. This system has been engineered using the highest quality materials and components. The dual rate front coil springs combined with our ICON 2.5 Series CDCV shocks give these trucks the performance they so desperately need. This system comes complete with front coils, shocks, radius arm drop down brackets, rear blocks and U-bolts and our patented adjustable track bar giving the front end of these trucks perfect track alignment. The Stage 4 system also includes shocks that feature the ICON Compression Damping Control Valve (CDCV) and our 4-Link kit for the ultimate in shock technology and suspension technology.

- CDC Valve shocks are application specific tuned like all ICON shocks
- Internally calibrated per application based on motion ratio, shaft diameter, and vehicle weights
- 10 detented stops and large adjuster knob provide easy-to-feel adjustments
- Allows the end user to optimize vehicle's ride specific to his/her liking on all types of terrain
