Question:
My 5th is a 2025 Cougar 23mle with a Road Armor pin box, I'm towing with a Ram 3500 dually. The stiff suspension bounces the light 5th wheel a lot, so I was wondering if the Helux would soften the stress to the rig. SN S012632845 LCI 20230183731 RPO 0013278714 12/17/2024

Hey Steve, thanks for the information! Your 2025 Keystone Cougar 23mle has a 1621 pin box. The Curt Helux would help you with the stiffness and bouncing but they only fit a Rhino pin box.
Instead, I recommend the Gen-Y Hitch Shock Absorbing 5th Wheel to Gooseneck Pin Box item # GY38FR. This pin box has torsion rubber flex springs in it that absorb road shock. They really work well in stopping bouncing and limiting chucking and vibrations being transferred to your truck. The torsion springs do a great job of moving up and down to stop excessive vertical movement.
You will also need the Safety Chain with 2 Hooks for Gen-Y 5th Wheel to Gooseneck Pin Box item # GY49GR. Safety chains are required for gooseneck connections and they are not included with the pin boxes. These will attach to that cross looking cutout by the Gen-Y logo.
Are you just traveling on regular highway roads when you start bouncing around?
