Replacement Convertible Tops

Your convertible top allows you the ability to drive with or without the roof. The convertible top can be retracted and stored as needed, allowing an open-air driving experience. Usually made of vinyl or canvas, these replacement tops fit over the steel, aluminum, or plastic frame.

At GAHH Automotive, we produce replacement convertible tops that are ready to install and guaranteed to fit. Many convertible tops are available in a variety of materials and colors. Some vehicles have tops which include both a cover section and a separate window section. All Gahh convertible top replacement kits have been extensively tested and evaluated to ensure high quality standards.

Infinity Window System

INFINITY™ Window Systems

Cosmetically and structurally equivalent to OEM.

CONVERTIBLE TOP INFINITY™ ULTRAMAXX AND WINDOW SYSTEM

In 2008, GAHH introduced the revolutionary convertible top UltraMaxx system. This system has solved bond failures and eliminated unneeded stitching and piping. Seams are stitched and then heat-sealed from the inside for a clean look and long-lasting protection from separation or leaks.

In 2017, GAHH again led the industry with the introduction of the convertible top INFINITY™ WINDOW SYSTEM. It incorporates an engineered support structure and a direct to top material for glass bonding. It ensures that the resulting aftermarket convertible top is equivalent to the OEM top both structurally and cosmetically.

Attachments are compatible with new convertible vehicle designs to make convertible top installation quicker. Lightweight injection-molded rings use the same materials as the OEM.

INFINITY™ INTEGRATED CONVERTIBLE TOP WINDOW SYSTEM

With the invention of convertible tops that open and close while the vehicle is in motion, OEM engineers had to create an integrated window structure with an extremely strong and precise ring.

GAHH Automotive Infinity™ Ring is the only aftermarket system that meets these requirements through injection molded rings using the same materials as the OEM. Anything else is only an imitation that will risk ring breakage and field failure. The Infinity™ Integrated Window System features a direct bonding to the material with a no "rolled edge"; The glass sits directly on the top. Our proprietary tooling and equipment provide a superior finish and bond strength.

OEM EQUIVALENT FOR NEWER VEHICLES

Attachments are compatible with new convertible vehicle designs to make convertible top installation quicker. Lighter weight injection molded rings use the same materials as the OEM.

5 Year Limited Warranty

GAHH's Infinity™ Integrated Window System has a patent-pending bonding system engineered to last. By integrating the window structure fully into the frame, we can confidently guarantee the window bond will not separate, delaminate, leak, or fall out.

UltraMaxx Window System

UltraMaxx Window System

 

For most glass window models before 2015, we offer our 5-year limited warranty on the UltraMaxx™ Glass Window bond. When developing the convertible top UltraMaxx™ Window system, our engineering team set forth to develop a process to address the problems of separation and leakage. It has the added value of a more "factory finished" appearance. After hours of researching, prototyping, and testing, GAHH Automotive developed a new patented process that virtually eliminates the inherent problems of heat seals or silicone.

A completely automated system was designed to manufacturer the window tops. Developed for GAHH Automotive, 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.

The resulting bond between the glass and the topping is quite durable. Trademarked and patented as UltraMaxx™, these windows set a new standard for pre-2015 glass window tops.

 

Testimonials

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.

Porshaw Boulder, Colorado

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.

Mark Gelefsky New Jersey

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.
