We have a 2017 Raptor 425TS toyhauler and want to upgrade our 1611 Rotoflex pinbox. What products will fit our pinbox? Ive attached a picture of our chassis tag.

Expert Reply:

The Rota Flex pin box comes in either a 1621 # LC328330 or 1116 # LC176440 bolt pattern.

For an upgrade I recommend the Trailair Flex Air 5th Wheel Pin Box # LC369535 for a 1621 bolt pattern or the Trailair Air Ride 5th Wheel Pin Box # LC155943 for a 1116 bolt pattern. These pin boxes are both rated for 21,000lbs to ensure you safely tow your 2017 Keystone RV Raptor 5th Wheel Toy Hauler 425TS with a 15860lbs dry weight. The Flex Air drastically reduces chucking, absorbs road shock, and minimizes bounce. The internal air bag and built-in strut work with the rubberized pivoting head to achieve a dramatically smoother ride than you were experiencing with your Rota Flex.

Your picture didn't attach so I don't have the info to confirm what your current pin box is so you'll want to double check your tag to ensure which bolt pattern you have before purchasing your new pin box.
