UltraMaxx Window System
For most window models prior to 2015 we offer our limited lifetime warranty on the UltraMaxx glass window bond. When developing UltraMaxx our engineering team set forth to develop a process to address the problems of separation and leakage with the added benefit of a more “factory finished” appearance. After hours of researching, prototyping and testing, GAHH developed a new patented process that virtually eliminates the inherent problems of heat seals or silicone.
Completely automated equipment had to be designed to manufacture the tops. This proprietary process involves wrapping the topping around an internal support structure and adhering the glass to the resulting assembly with a special bonding agent, developed specifically for GAHH Automotive.
The resulting bond between the glass and the topping is extremely strong, and also has no stitching or piping. Trademarked and patented as UltraMaxx™, these tops have set a new standard.
New GAHH top! I called all over looking for the best price on a new back window replacement. I had a local shop install a GAHH top at a great price! How could I pass that up He did the install in 1 day, and I just got it back. Well worth the money!!! Besides its hard to drive with duct tape on your window.
Convertible top for a 2001 Porsche Boxster S. "I got my car back today and it looks PERFECT now! GAHH really came through to make me happy.
More than likely the top manufacturer is GAHH in California. A very reputable company. They use the original "Sonnenland" A5 topping material made by Haartz GmbH (formerly Rode and Schwalenberg) in Germany. Try www.gahh.com and you can probably find a local distributor in your area that distributes their tops. As far as I know, they are the only top manufacturer currently making a '97-'02 replacement top with a glass rear window. More manufacturers will surely follow but may not use the original equipment material.
