Pullrite Super 5th. Available in 16K, 20.5K (Pictured), 25.5K, and 25.5K adjustable. Rotary latch design provides tighter connections between the truck and the trailer for more comfortable towing. Super 5th hitches are built with precision fit, laser cut parts. There is only .030" tolerance between the king pin and latch - minimizing the "bump" felt when towing. The dual tilt articulating head pioneered by Pullrite eliminates twist and stress on trucks and trailers.
