Installation Instructions

Tools Required: 15/16″ wrench and impact wrench with 15/16″ socket.

  1. 5th Wheel Pin Box for Air Ride Kingpin Installation: 5th Wheel Pin Box for Air Ride Kingpin Installation: On a level surface, take a measurement of your current pin box from the flat plate to the ground and make note. This will be applied to the Shocker Hitch Quick Air system. Unbolt your existing 5th wheel pin box with a 15/16″ wrench and impact with a 15/16″ socket from your camper trailer and any brake cables. With assistance, remove your 5th wheel pin box and set it aside and/or put it away in storage. With assistance, slide the Quick Air 5th wheel pin box in between the camper trailer’s pin box brackets. Once lined up in the correct adjustment holes of the brackets, use the previous pin box’s hardware to install the Quick Air pin box. Before sliding the Quick Air pin box in place, it is recommended to use spray grease/lubricant on the pin box brackets to assist installation. NOTES: Some applications may require spacers for the Quick Air pin box to fit properly. Torque to 120 FT pounds. IMPORTANT: DO NOT overtighten the pin box bolts as this can lead to premature wear and possible failure in the pin box. It is highly recommended to use additional washers on the backside of the pin box bolts.
  2. Shocker Hitch Air Ride System with Kingpin Installation: The top side of the hitch unit has stud like bolts sticking out from the top of the frame. With assistance, insert these “studs” through the pin box and start to thread the provided washers and nuts hand tight. With assistance, take the provided washers and bolts and hand thread the bottom side of the hitch unit to the pin box by hand and finish tightening with an impact wrench with a 15/16″ socket. IMPORTANT: DO NOT overtighten the bolts or nuts to prevent any stripping or cross threading.
  3. Hooking Up to 5th Wheel Hitch in Truck Bed: Hook up using the 5th wheel hitch like normal. It is recommended to use a 5th wheel scuff plate or to grease the 5th wheel head before hook up. This helps the hitch rotate and prevents any premature damage. IMPORTANT: Always double check that the 5th wheel head has latched correctly and that any safety pins or brake lines get re-installed for safety.
  4. Step 1, remove your factory pin box and replace with the quick air 5th wheel pin box using your oe factory bolts.
  5. Step 2, bolt the surge air hitch into the quick air pin box using the supplied bolts and flange nuts.  Secure the bottom back bolts with 15/16″ wrench, then secure the top flanges nuts.
  6. Step 3, set your air pressure to 15 psi to start.
  7. Please note: Kit Does Not Include Pin Box Bolts (Existing Bolts are used for installation).
