GT2, GT3 3rd/4th Gears
If you can select a ratio, we have it in stock and ready to ship. Prices will vary depending on the gear selected.
IMPORTANT NOTE: The standard bore of a G50 and 993 3rd/4th idler gear is 50mm. Some of the short ratios have a 47mm bore which requires the use of this bearing kit.
- Porsche 993 3rd gear ratios between 1.632 (19:31) and 1.773 (22:39) have a 47mm bore and require this bearing kit.
- Porsche G50 5-speed/950 3rd gear ratios between 1.500 (20:30) and 1.700 (20:34) have a 47mm bore and require this bearing kit.
- Porsche GT2-GT3 3rd gear sets all have a 47mm bore. A gearbox with a standard mainshaft will require this bearing kit. Please keep in mind that newer replacement shafts provided by Porsche may require a different bearing race, and as such requires consultation. Please contact us so we can provide the correct bearing kit for your specific application.

All Albins gears receive the standard anti-fatigue shot peening treatment and are manufactured using a proprietary grade of steel.
We carry two different manufacturing styles of gears:
- Profile Ground - This finishing process is how original Porsche factory gears are manufactured. The result is a quieter, stronger and longer lasting gear that's equally at home on the track or in the city.
- Hobbed - A fantastic choice for track racing where noise is not a concern. You get high quality gears, and your wallet gets a break on the price.

Any abandoned packages are the responsibility of the customer. In order to comply with export regulations, we are required by U.S. law to declare the exact value of all items ordered and to mark them as dutiable "merchandise." Declaring less than the true value is both a violation of U.S. law and the laws of most other countries. In addition, we could lose the right to export to your country should it ever be discovered that we were misrepresenting the value.
