All hardware should be tightened only enough to ensure safety during assembly. Fully tighten all hardware after entire assembly is completed.
1. Insert pairs of 5/8 inch x 7 1/2 inch and 5/8 inch x 8 inch hex bolts through holes in four 1/2 inch thick top bars from the kit. Place the 7 1/2 inch bolt/bar assemblies over the side rails of the vehicle ahead of the cab mount structure. Place the 8 inch bolt/bar assemblies over the side rails behind the cab mount structure.
2. Lift the LH and RH bracket weldments to the bottom of the corresponding frame rail and push four bolt ends through holes in the bracket. The front edge of the cab mount structure will fall within the notch in the bracket when the bracket is positioned correctly front to back. Loosely thread four 5/8 inch lock nuts onto the bolt ends to hold the brackets in place.
Model year 2006 and later trucks have smaller frame rail cross sections that require additional hardware when installing this kit. Insert shim straps between the inner sets of bolts and the frame rails to eliminate lateral slack. Install two 5/8 inch flat washers under lock nuts on the four 8 inch long bolts to compensate for shorter rail heights.
3. Fasten the mount plates of the prong weldment to holes in the LH and RH brackets with four 5/8 inch x 1 3/4 inch hex bolts and lock nuts.
Bottom edges of the prongs should measure about 10 inches above the ground. Ideally the prongs should lift the plow frame slightly when driving into the plow.
4. Fully tighten all mount kit hardware to specified torque values.
5. Loosen the bumper mounting hardware, then push the bumper to its highest position before retightening to create maximum clearance for the plow mount. In some instances the plastic trim along the bottom of the bumper must be notched or removed to provide clearance for the plow mount.
