I decided to start a new thread because the original was becoming fragmented and long.
There have been reports from a very few (3)of those who have purchased the Sullybilt system that there is a lack of clearance to the interior vertical wall of the wheel well with the new larger airbag. It appears that a great disparity exists in the distance between the bogie arms and the inner wheel well on our coaches. This disparity likely has many causes including manufacturing variances, design changes, coach age, condition and positioning of bogie arms, and owner modifications. I personally would not want to buy a suspension product which required major modifications to my wheel well or strayed away from the original suspension design. For the above reasons, I have come up with a newly designed model of the Sullybilt system to accommodate those with reduced clearance on the wheel well. The kit is the same price as the original system and uses the same mounting hardware and Firestone air spring but provides for an additional 1/2" of clearance of the Plates and airbag. The only information I need from those who desire the kit is a simple measurement from the center of the existing airbag mount stud to the vertical wall of the wheel well.
THE AIRTECH AIRBAGS WHICH ARE SUPPOSED TO BE A DIRECT INTERCHANGE FOR THE FIRESTONE RUN WIDER AT OPERATING PRESSURE AND WILL INCREASE THE PROBABILITY OF A CONFLICT. I DO NOT RECOMMEND USE OF THE AIRTECH AIRBAG WITH MY KITS.
I will soon have the video of the installation I performed at the GMCMI convention earlier this year at Shawnee. Once I have it edited I will post a link to it on my website as well as some photos of the measurement being taken so you can be sure it is done correctly at the correct location. Those of you who may be on the fence about purchasing this system should watch the video and see how sturdy this system is and the ease of installation. I believe after viewing you will be convinced of its value. I will post another thread when I have updated my website with the video and other new information.

I am one of those that has a clearance problem with the Sully system. In my case it appears that problem exists because of the AirTech bags that I purchased for the conversion. While the Airtech is suppose to be a direct replacement, at operating pressure, they are actually about 1/2" or more, in diameter larger than the Firestone bag. Todd has bent over backwards to accommodate my problem, so folks...it looks like we have another good vendor that stands behind his product. I also would NOT recommend the use of the Airtech bags for the Sullybilt system. I'm stuck with them now because as part of the installation I had to saw off shorter one of the mounting studs. In addition, Todd is right, the system is VERY easy to install. Soon I will have the replacement plates and will install them.

I am here to echo what Larry has said.
I too installed the Sully system with the AirTech bags and I have the interference problem.
Todd has been more than supportive and has initiated quite a bit of dialogue to help us figure out and understand the problem we have. I agree with Larry that Todd deserves to be one of our premire suppliers.
I have attempted to contact the Air Spring Store, supplier of the AirTech bags but without response. Soooo, I will order a set of the REAL Firestone bags and try to get this issue sorted out.
Even with the bags rubbing, and a lot of silicone spray on the contact areas, I really like the ride and handling with Todd's system.

Hello,
I noticed someone had used silicon spray, i would worry if it got in contact with the bags, that it could cause deteriation of the rubber over time ???. But perhaps nothing to worry about.
