Recent posts about pressure related issues and the Quadra Bag rear suspension system has prompted me to restate qualities of the Sullybilt rear suspension system which are core to the reasons for its development and success.
There is no need to change, adjust or replace ANY part of the existing air supply or metering hardware on a properly functioning coach system to utelize the Sullybilt sytem. The ONLY part which needs to be touched is the airspring itself.
If you have at least one oem airspring which will hold air then you already have a free spare to carry in the unlikely event you have an airspring failure. If a tire were to come apart and damage the airspring, the existing leftover oem bag can be reinstalled at the same time as the spare wheel and you are on your way. The complete Sullybilt sytem is removed as an assembly and the oem airspring put back in its place. No plumbing or ride height mechanical changes are required as the ride height is read by the oem sytem off of bogie arm movement not air pressure.
Installation of the Sullybilt system requires properly supporting the rear of the coach under or near the bogie box, depressurizing and removing the existing oem airspring and replacing it with the Sullybilt assembly. Often the most challenging part of the installation is removal of rusted T skirt fasteners (if coach is equipped with such) or frozen oem airspring fasteners.
The Sullybilt single airspring system operates at a much lower air pressure ( typically 35-60psi are the norm as compared to the oem sytems which see typical pressures over 100psi) which takes a lot of load off of existing compressor sytems which are "past their half life by now".
The Firestone W01-358-9294 which is used with the Sullybilt sytem has a HIGHER load rating than the oem airspring and thus likely a higher load rating than the currently produced copy of the oem airspring. The FI 9294 airspring also has an integrated internal rubber bump stop which can prevent undercarriage and wheel well damage in the event the motorhome is moved while an airbag is deflated or a sudden loss of pressure is experienced (catastrophic airspring failure) while underway.
Simplicity/oem like performance/ease of installation/dependability/low cost compared to other available systems.
