Recommended Replacement For A Lippert 1621 Pin Box With A Pull Rite Super Glide Hitch


I have the Lipperd 1621 king pin with a pullrite super glide hitch in my short bed crew cab truck. I would like to find a better pin box for a smoother tow of my 5th wheel. Is this pin box compatible with my current hitch?


Expert Reply:

The Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 18,000lbs Item # LC328492 you linked to will replace your Lippert 1621 pin box and offer you a much smoother ride. The Internal air bag absorbs road shock and built-in shocks ensure that the pin box rebounds and keeps the air bag from breaking down. The scissor-like motion allows pin box to compress, compensating for jarring and bounce and limits chucking by allowing controlled movement of the king pin within your hitch.

This is rated for 18000lbs GTW so if you need a larger weight capacity you'll want the Trailair Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000lbs Item # LC369535.
