All of the suspension components are covered by ICON's Life-time Warranty and the shocks have a one year warranty against leaking. This 4.5" System for the 2008-2010 Super Duty's is one the best riding suspension systems ICON has ever developed. This system has been engineered using the highest quality materials and components. Not only are these shocks capable of gobbling up any terrain, but the 4-link conversion has the ability to control the axle much more efficiently in comparison to the factory radius arm system. By converting to a 4-link, you will notice a vast improvement in ride quality, greater articulation, and less axle dive.
The front Dual-Rate coils-springs combined with the ICON 2.5" Omega Series Piggy Back shocks give these trucks the performance they so desperately need. This system comes complete with front coils, shocks, adjustable 4-link system, rear blocks and u-bolts and ICON's patented Adjustable Track bar with upgraded bearing giving the front end of these trucks perfect track alignment.
ICON's Stage 4 System upgrades the front and rear shocks to ICON's 2.5" Omega Series Modular Bypass shocks for on vehicle adjustment of rebound and compression. The stage 4 system also includes ICON's 4 - Link kit as well as ICON's dual opposed steering stabilizer kit and shocks.
