Between the Curt Flex Air 5th Wheel Pin Box - Lippert 1621 - 21,000 lbs Item # LC369535 and the Curt Air Ride 5th Wheel Pin Box - Lippert 1621 & 1621HD - 21,000 lbs Item # LC158778 there is no difference in their bounce and chucking reduction. The only difference they have is there is a slight dimensional difference between the exterior bushing width measurements. LC158778 is 14-13/16" and LC369535 is 16-1/4".

Both Pin boxes eliminate bounce and shock from the road with their internal air bags which will cushion your ride, improve handling, and limit strain on the truck and trailer.
