Wondered if anyone had the "hot" set up with their 2500 HD Chevy pulling a 5th wheel. Currently have a Curt Q20 in the bed. Installed the Rancho adjustable shocks and Firestone airbags to cut down the bounce and bottoming out. The airbags made a significant improvement to cut down on bottoming out but still have some bounce. I crank the Rancho's all the way up for dampening when I pull. I called Firestone and spoke with them about better shocks. They said I have the best that I could hope for. Would like to do better on the bounce. Any ideas?

Bilsteins. I never had much luck with Ranchos or any adjustable shock.

JMO but if your 9000's are in good working condition then Bilstiens probably won't make enough of a difference. Sounds like you have some other issue causing the bounce. Maybe an air hitch would be money better spent.

More infö….What your pulling?, speed? Pressure in bags?

Have to agree with the others, Bilsteins because of their design stops over rebounding and It puts a stop to porpoising. I have used them on all of my heavy vehicles and they have performed better than any others.E Shocks is the cheapest and most reliable place to buy them. They will answer any questions that you may have.
