Rivco Products Trailer Hitch Kit GL18007 The complete package weighs only 8 lbs. including the mounting hardware, ball and wiring. It bolts to the MAIN FRAME ONLY! There are no attachments to the sub-frame. This is an extremely important feature as the GL1800 sub-frame is made of thin wall aluminium tubing and CANNOT withstand the additional load, stress and vibration from a trailer for long. Maximum trailer capacity 600lbs maximum recommended tongue weight 50 lbs.This hitch is strong enough to be used to lift the 834 lb. The tongue fits into a horizontal receiver block located just behind the fender. When not in use, the hitch pin and tongue can be removed from the receiver block in seconds. A spring clip is provided that bolts to the original reflector allowing it to be snapped into the hole in the fender- making the hitch completely hidden. Also included is our electronic trailer wiring isolator unit which plugs into the GL1800s wiring harness. The isolator unit is a must as it protects the GL1800s sensitive electronics while providing full battery voltage to the trailers lighting.
