Porsche's 901/904 transmission equips Porsche 911 ('64-'68), 912 ('69-'73), 914/6 ('70-'76), as well as race cars 904 - Carrera GTS, 906 - Carrera 6, 910. With Retro Sport gears you can customize your gearbox with a huge range of gears and ring & pinions for nearly every generation of classic Porsche transaxle.
We have the largest inventory of classic Porsche gears in the U.S. and we are the exclusive distributor of high quality Albins® Porsche gears in North and South America.
Explore new ratios that have never been manufactured before Albins® put them into production. This gives you the freedom to tailor your gearbox to any possible application - road racing, rally and V8 conversions.
Choose from a wide selection of rare original factory gear ratios, most of which are no longer factory manufactured and extremely hard to find in good condition.
We carry two different manufacturing styles of gears - the original hobbed style, and the new profile ground. Profile grinding is the same process used to manufacture Porsche factory gears and allows for stronger, quieter, and longer lasting gears.
All Albins® gears receive the standard anti-fatigue shot peening treatment and are manufactured using a proprietary grade of steel.
Contact us to request a consultation on your specific application. Whatever your circumstance, we'll work with you to find the gear ratios and ring/pinion combinations that work best for your driving needs.
