I guess that's possible, but I like the air bag option better for functionality and preserving the articulation when just riding trails in the truck with trailer. The Timbrens are still just rubber stops like the OEM stops but a higher grade and larger. Perhaps if it had the Bison jounce control hydraulic stops it would be a different story but those are $$$ as an aftermarket upgrade and still passive. I prefer the adjustability of air bags, in theory anyway. I've had factory bags on cars and loved it.
