VW T3 Syncro GT gears
For many of you out there running higher powered engines, heavy campers, bigger wheels and peace of mind. I am pleased to announce that I shall be able to provide you with the option of heavy duty GT Gears for your Syncro. Which, as far as I am aware of, are the only gear manufacturer to offer any type of warranty on their gears especially for larger than stock engines (although I could be mistaken). They are not cheap but the option is there for those who are interested. They also do Crown and Pinions, Mainshafts and billet cases and other bits and bobs anyhow heres some highlights from their website and the samba article about their gears
 

“Guard Transmission utilizes the most advanced and modernized CNC gear-cutting equipment available. All of our gears are cut with class AA grade gear hobs and feature the latest F1 gear profiles. Contact pressure angles are optimized for maximum strength and each gear tooth has a very prominent “tip relief” placing all contact directly in the center of the tooth. This special feature eliminates any premature wear found in all prior gear designs., which typically occurs at the base and tip of each gear tooth.

All gears offered by Guard Transmissions are shot-peened to Aircraft specifications, which normally doubles the service life (in medium stress applications).

Stronger, quieter longer-lasting. It has always been the goal of Guard Transmission to offer gearsets that are so superior in quality, that even the most discerning European race teams would take notice. 

Guard gears feature modern F1 tooth profiles. Helix and pressure angles are optimized for maximum strength. Each gear tooth has a very prominent “tip relief”, placing all contact directly in the center of each tooth. This reduces premature wear, typical in race use. Guard gears are also the only aftermarket gears to utilize Porsche ® factory German-made synchro teeth, and are the only aftermarket gears to have been sold directly to Weissach’s racing division.

 

For high horsepower Turbo applications, we strongly recommend our straight-cut synchronized gears (especially in 3rd & 4th gear positions), available in the above ratios.
Our billet mainshaft sets have a 30% higher torque rating than standard factory mainshafts, due primarily to the quill-shaft design.”

“GT gears feature an F1 racing gear tooth profile, with helix angle adjusted for quieter street operation. They won’t wear out prematurely or in a cocked pattern, but rather they’ll develop uniform wear as shown on this used GT gear. (Note the prominent tip relief feature in the design, which eliminates wear on both tooth tip and tooth root.”
