Just returned from Carli suspension after swapping my Firestone Ride Rites for Carli's new long travel airbags which provide 10" of travel. Surprisingly,while providing very good sway control and leveling,they are very forgiving and allow my Lorenz system to articulate through its manufactured range. I'm running 35psi in order to level the truck which is 5psi under the Firestone setting but the difference in travel is amazing. This is not intended to bash Firestone's product which is a very cost effective solution to carrying heavier loads under highway or service roads,but Carli's product enables the truck to support the load while minimizing articulation reduction. Sage and Mike did an excellent install,which included a "trial run" over the area's train tracks and poorly maintained service streets which was the closest to "off-road" we could simulate in beautiful downtown Orange,Ca. I recommend this product to anyone in need of controlled load carrying capacity,while minimizing spring travel loss.
