Frequently Asked Questions
What is an air ride 5th wheel pin box and how does it work?
An air ride pin box replaces your standard rigid pin box with a suspension system that uses an internal air bag to absorb road shock and trailer chucking. This reduces vibration transferred from the road to your trailer frame and living space.
Is the Curt #807710 compatible with my 5th wheel trailer?
This pin box fits trailers with a standard 5th wheel kingpin mounting pattern and a tow capacity up to 21,000 lbs. Always verify your trailer's existing pin box mounting pattern before ordering.
How much does the Curt Air Ride Pin Box weigh?
The unit weighs 167 lbs. and measures 44.5" x 22" x 21.5". Plan accordingly for installation — a second person or lift assist is recommended.
What is the difference between air ride and coil-spring pin boxes?
Air ride pin boxes use a pressurized air bag for a softer, more adjustable ride — ideal for long highway trips. Coil-spring models like the Curt Helux series offer a firmer, more controlled suspension suited for heavier loads up to 24,000 lbs.
