The ICON 2008-2022 Ford F-250/F-350 Super Duty 4WD Front Box Kit is an essential component of ICON 4.5 lift suspension systems. Front sway bar drop brackets fabricated from CNC laser cut steel plate ensure bind free motion of the sway bar links through the entire range of suspension travel and are powder coated for corrosion resistance. CNC laser cut and brake formed brake line drop brackets eliminate the need for aftermarket brake lines and allow the OE brake lines to be used without the need to open up the brake system during install. Bump travel is properly limited with robust CNC machined 6061 aluminum bump stop spacers that are designed for the stresses of aggressive offroad driving. Wheel with confidence that all of these components are covered by ICON Limited Lifetime Warranty.
