Picture is for sample use, may not be actual bars

Step 1:

Open and identify the bars. The short end of the bar goes towards the front of the vehicle.

Position the bar up to the truck approximately ¾” to 1” from the front wheel well opening.

(If you have over-sized tires you can mount the bar further back to insure you have tire-turning

clearance). Make sure not to hit the cab brace: this will cause the step plate not to be parallel

with the ground.

Step 2:

Hold the bar on the underside of the truck with the angled flange on the bracket below the pinch

weld. (Fig A) Use the slotted holes in the angled flange as a guide to mark the holes to be

drilled into the pinch weld. (6 per side, the angle of the flange will appear to be at a different

angle than the pinch weld this is normal and the bar will “set” properly when installed. ) Once

holes are marked carefully set the bar to the side.

Insert a 5/16” carriage bolt into each hold and fasten with a washer and nut. (Finger tighten only at this time.) Tighten the bolts at the front first, then move to the back of the bar. Holding the bar parallel with the truck tighten the rear bolts securely.
