Assembly includes measuring the height requirement for the Q20 5th Wheel Head in relation to your trailer ride height at the kingpin
box and skid plate. Ideally the trailer should ride as near to level as possible. The Q20 5th Wheel is adjustable from 13 to 17 inches
from the pickup bed to the top of its Skid Plate. Adjustment is attained by adjusting the Mid-Section up or down in relation to the legs
in 2 inch increments (typical clearance between the pickup bed rails and the trailer should be a minimum of 5-1/2 inches.)
Step 1. With your trailer on a firm and level surface, set chock blocks in front of and behind the tires. (Do not substitute wood blocks,
rocks, etc. for chock blocks.) Extend front trailer lifting jacks, adjust as required to set trailer at or near level.)
Step 2. Measure from the ground to under the trailer’s kingpin box skid plate (or Lube Plate if used). This will be the portion in
contact with the Q20 5th Wheel’s Skid Plate once coupled.
Step 3. Measure from the ground to the surface of the pickup bed.
Step 4. Subtract the measurement from Step 2 from Step 1. This value will be near the height requirement for the Q20 5th Wheel.

Very Important! Torque the four pilot bolts to 100 ft-lbs. Retorque after initial 500 miles and every 1,000 miles
thereafter and prior to each individual use.
Step 1. Depending on which holes are selected, attachment of the Legs to the Mid-Section may be easier with the Mid-Section
upside-down sitting on its Skid Plate.
Step 2. The Head Assembly can be removed from the Mid-Section to further aid in the installation of the pilot bolts.
