SHOCKERHITCH SH-RVGC-4405 Air 5th Wheel to Gooseneck Air Hitch and
Coupler Conversion
Product Information
The QuickAirTM 5th Wheel to Gooseneck Air Hitch & Coupler Conversion is a heavy-duty unit designed for towing purposes. It has a maximum tow weight capacity of 25,000 lbs and a tongue weight capacity of 6,000 lbs. The hitch is equipped with a 2 5/16 diameter ball and is V-19 rated. Please note that this gooseneck hitch has a shorter stem than a normal gooseneck and is specifically designed for use with the Shocker Replacement Goose Box for 5th Wheel Campers only. It cannot be used on a normal gooseneck trailer due to the shorter inner tube steel.
Installation Instructions
- Remove your existing kingpin box and install the Replacement Goose Box (SH-RVGC-4405 or SH-RVGC-4410) in the same location on your camper.
- Torque pin box fasteners to 120 ft pounds.
- Test fit of the camper to the truck and verify that the installed height allows the camper to ride level.
- Apply grease to the trailer ball and/or shift lock coupler ball socket.
- Hook up the trailer by shifting the lever back and lowering the coupler onto the ball.
- Pull the shift lever forward and align the locking hole, then insert the pin.
Routine Lubrication Maintenance
Regular lubrication maintenance is recommended to reduce wear and improve shocker action. The following components should be lubricated periodically:
- Oil the coupler shifting fork shafts
- Grease the coupling ball socket
- Grease the hitch ball
- Grease the main pivot grease zerk for maximum bushing life
- Note: You cannot over-grease it!
Setting the Air Pressure
The QuickAirTM hitch operates on low pressure and works based on tow resistance. Follow these steps to set the air pressure:
- Initially, set the air pressure at 15 psi.
- Take a test drive to assess the performance.
- If needed, increase the air pressure in 5 psi increments and test drive again until optimum results are achieved.
- Keep in mind that trailers with heavy weight or high wind resistance may require higher air pressure in the Shocker hitch.
- Do not exceed 100 psi in the airbag as it may damage the air bag. For any further assistance or inquiries, you can contact Shocker Hitch through the following channels

Use only a 2 5/16″ dia. Ball. V-19 rated: 25,000# G.V.W 6,000# Tongue Load. Do not exceed G.V.W.R. of ball being used.
Note This gooseneck hitch has a shorter stem than a normal gooseneck and is designed to be used with the Shocker Replacement Goose Box for 5th Wheel Campers only. This gooseneck air hitch cannot be used on a normal gooseneck trailer as the inner tube steel is too short for that application.

- To adjust trailer ride height simply loosen the ½” x 1″ set bolt in the back of the down tube. Remove the 3/4″ x 5″ thru pin with keeper. Move Shocker Gooseneck Surge hitch to desired position, reinstall bent pin with keeper and tighten set bolt.
- Routine Lubrication Maintenance should include: Oil the coupler shifting fork shafts, grease the coupling ball socket, and grease the hitch ball to REDUCE WEAR AND IMPROVE SHOCKER ACTION. Main pivot grease zerk should be greased periodically for maximum bushing life. ( Simply, you cannot over grease it! )
Setting the Air Pressure
This is a LOW PRESSURE hitch, that works by tow resistance. Note all trailers
have a different tow resistance. Initially set air at 15psi, Test Drive, THEN
Increase pressure in 5 psi increments & test drive until optimum results are
found. Remember, pressure gauges may vary, use the same gauge when testing and
keep adding until the ride improves, eventually the hitch will get too stiff
and ride will worsen, reduce pressure to where the ride was best.
Note When towing heavy trailers or trailers with high wind resistance it
may be necessary to increase air pressure in the Shocker
Maximum Pressure: Do not exceed 100 psi in the air bag, as it may damage
the air bag. SHOCKERHITCH PO Box 162, 420 CTY RD 34, Arthur, ND 58006
