ALBINS 901 GEARS 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 engines power curves can make a huge difference on the track, often
resulting in reduced lap times, and can give the sensation of 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. 901 GEAR LIST ·

ALBINS 901 SYNCHRO TEETH Sometimes termed as dog ring or synchro hub, these
are the teeth that your shift sleeve/slider engages into. If you have a bad synchronizer and if you
have been grinding going into gear-you probably need to replace this part. These are a direct replacement for both OEM and
Albins gears. ·

teeth $199 ·

or 5th gear synchro teeth $199 |

CMS 901 EARLY BILLET SIDE PLATE At last, a strengthened side plate for the early
aluminum case transmissions! Fits all
vintage Porsche 911 and 912 short wheel base cars 65-68 (some early 69). With the ever so increasing power of today’s race
engines and the stick of today’s tires you are starting to put some serious
stress on your original cast side cover, especially under track conditions. As the side cover acts as a thrust plate,
under load there can be a tremendous force applied to it, and it can break
sometimes causing damage the ring and pinion-or worse. Upgrading to a billet side plate will add
significant strength and reliability to the differential section. ·
Precision machined from aircraft grade
billet aluminum to exacting standards for perfect fit and function ·
Oil passageway for standard taper roller
bearing ·
Removable billet clutch cable bracket ·
Uses rubber o-ring instead of paper
gasket Note: The cover is thicker than the original and
therefore requires longer studs to be installed. INCLUDED! $329 Installation instructions |

CMS 901 BILLET INTERMEDIATE PLATE The factory cast magnesium intermediate plate is
known to be problematic. Original ones
tend to crack, have loose or out of round bearing bores or may have worn out
shift shaft provisions. Perfect for street, race, higher horsepower and V8
applications-where the additional strength is really needed! ·
Precision machined from aircraft grade

which are replaceable ·
Input shaft bearing oilier ·

A diff bearing oiling provision ·
Uses large 930 turbo diff bearing ·
Uses o-ring instead of paper gasket ·
