The CURT A20 5th wheel hitch offers smoother, quieter towing for your home-away-from-home, combining the patented technology of our A-series, an easier mounting system and the power of a 20K 5th wheel hitch. Like our A16 hitch, this 20K 5th wheel hitch uses a patented cast yoke to allow for unimpeded head movement, while providing exceptional stability for the trailer. The yoke has a set of poly-torsion inserts to suppress shock loads and reduce excessive noise, and the head features high-strength, interlocking jaws to give the trailer stability and the freedom to pivot and swivel as needed. The A20 is also fast and simple to operate. It has a lockable, single-throw handle that self-resets to the ready-to-couple position after uncoupling, and it is equipped with a coupling indicator that shows the coupling status. This 20K 5th wheel hitch comes with the CURT R20 slider and the CURT OEM puck system 5th wheel slider adapter. It is designed to be mounted on select Chevrolet or GMC short-bed pickup trucks with the truck bed puck system (year range specific). Using a set of quarter-turn anchors, the adapter quickly and easily drop into the pucks, instantly mounting the A20 hitch and slider and equipping the truck for 5th wheel towing. Once installed, the R20 slider allows for added clearance when making tight turns with your trailer. CURT 5th wheel sliders are true rolling units, meaning they actually roll on wheels that bear the weight of the trailer rather than simply sliding on hollow rods as seen in competitive models. CURT sliders also provide up to 12" of displacement as well, unlike the more common 10", to give you a wide range of motion and plenty of space to get your RV or other 5th wheel trailer around any turn. This A20 hitch with puck system slider is only intended to fit select Chevrolet or GMC trucks with a year-specific puck system and cannot be installed without it.
