MAD-RAMPS Pivoting Ramp System
Installation Instructions
MAD-RAMPS ASSEMBLY GUIDE
NOTE: All ½ inch jam bolts used for assembling the MAD-RAMPS Pivoting Ramp System
must be torqued to 70 ft/lbs each. Please check jam bolts for proper torque after first use and
periodically thereafter.
Step 1:
Start the assembly process with the tailgate of your truck in the up-right position. Pre-thread two
of the provided jam bolts into the Bumper Guard (part #9), as shown in Figure 1. Slide the Bumper
Guard onto the receiver end of the Main Arm (part #6), as shown in Figure 2. Then insert the Main
Arm into your truck’s receiver hitch. Secure the Main Arm into the receiver hitch with a pin and key
(Figure 3). Adjustments to the Bumper Guard’s position on the Main Arm will be made in a later step,
so do not tighten the two jam bolts for the Bumper Guard at this time.
Step 2:
Pre-thread two of the provided jam bolts into the Light Bar (part #4), as shown in Figure 4. Slide the
Light Bar onto the angled end of the Main Arm (part #6), approximately ½ of the way down the Main
Arm (Figure 5). Adjustments to the Light Bar’s position on the Main Arm will be made in a later step,
so do not tighten the two jam bolts for the Light Bar at this time.
