Fabtech Dual Shocks Systems will allow you improve your vehicle's front suspension damping efficiency by running two shocks per front wheel. The Dual Shock system is for use with Fabtech's 6 inch RTS system, featuring a 1.5 in. Outside Diameter X .120 wall DOM tubing, with upper mounting hoops that bolt to the frame. This allows you to use the Fabtech Performance shocks and fully upgrade your suspension system. On trucks with already equipped Fabtech 6 inch RTS, the Dual Shock system works like a charm ? as the lower mounts have already been incorporated into the RTS, which simplifies the installation process. You won't have to mount the Dual Shocks to your vehicle's upper control arms but to the lower ones instead! Simple as that! Plus, the Dual Shock Systems come backed by a limited lifetime warranty to guarantee your investment.
