Like the other 5th wheel hitches of the CURT Q-series, the CURT Q20 is designed to offer the quietest 5th wheel towing possible. It does this using a spherical axial bearing. This unique pivoting mechanism is built into the hitch head and allows it to tilt with the 5th wheel trailer in any direction necessary. With its dual-locking jaws for 360-degree pin contact and three grease fittings for continuous lubrication, the spherical axial bearing provides smooth, safe, quiet towing, even with large 5th wheel trailers. The Q20 also makes the coupling process easier. It features a self-aligning head to help reduce errors when backing up to the kingpin, as well as a three-position coupling indicator that is visible from the truck cab, eliminating the need to get out of the vehicle to check the connection. This 20K 5th wheel hitch comes with a weight capacity of 20,000 lbs. and is finished with a durable carbide black powder coat for an excellent defense against rust, scratches and UV damage. This particular Q20 hitch comes with a set of CURT OEM puck system 5th wheel legs, designed to be mounted on select Chevrolet or GMC long-bed pickup trucks with the truck bed puck system (year range specific). Using a set of quarter-turn anchors, the legs quickly and easily drop into the pucks, instantly mounting the Q20 hitch and equipping the truck for 5th wheel towing. The anchors feature an adjustable design to perfectly lock the hitch into place and eliminate any chucking noises, and the legs are finished in a durable carbide black powder coat to be highly resistant to scratches, rust and UV damage. These legs are only intended to fit select Chevrolet or GMC trucks with a year-specific puck system and cannot be installed without it. Certain turret-style pin boxes, such as Sidewinder, are not compatible with CURT Q-series hitches and should not be used as they may create vehicle / trailer handling hazards. Please contact CURT Product Support for compatibility information.
