ALBINS 915 GEARS AND RING AND PINIONS

Stock gear ratios are designed for drivability and fuel economy and not necessarily for best performance.

Whether you have a stock motor or one that has been tuned your transmissions gear ratios may not be optimum for your driving needs. Optimizing your gears to match your engine’s power curves can make a huge difference on the track, often resulting in reduced lap times, and can give the sensation that there has been a gain in power. Alternative gear ratios can make the car more fun to drive or be more drivable.

We carry a wide selection of OEM and Albins gears to suit a variety of applications. Most racing ratios are only available in Albins new condition.
