Happijac Tie-Down KitDodge RamFrame mount tie downs work with your truck and frame to provide unsurpassed safety, strength, value and truck/camper handling peace of mind. Direct-to-frame mounting system attaches to the truck frame components from above and works in combination with the anchor plates, guide plates, stabilizing bar and the truck bed to create an l-beam truss structure. This unique l-beam structure provides unmatched tie down performance and security. Only Happijac tie downs prevent camper movements in all directions (forward-backward, up-down, yaw, pitch and roll). The complete frame mount tie down system consists of three key components: tie down kit, turnbuckles and stabilizing bar. Stabilizing bars sold separately.
