ALBINS 901 HEAVY DUTY BILLET SIDE PLATE The original differential side cover is cast
magnesium and most original ones anymore have hairline cracks that could
cause a failure. Under load there can
be a tremendous force applied to this cover, and it can break, sometimes
resulting in a damaged ring and pinion-or worse. Upgrading to a billet side plate will add strength
and increased reliability to the differential section. ·
Fits all magnesium case Porsche 911
69-71 and 914 70-76 transmissions ·
Precision machined from 6061 aircraft
quality aluminum ·
Uses OEM standard diff bearing, radial
seal and O-ring (not included) ·
Includes billet clutch cable bracket and
reducer bushing for small diameter clutch cable $549 |

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 1ST gear set (includes
reverse idler gear) $945
w/new synchro teeth ·
901 2nd gear set (weld on
type; requires core OEM input shaft; requires additional labor-not included
in price) $725

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. ·
1st gear synchro teeth $165 ·
2nd, 3rd, 4th
or 5th gear synchro teeth $165 |

ALBINS 901 RING AND PINIONS 4.43 and 3.44 available $2525 |

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 |

|
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
billet aluminum to exacting standards for perfect fit and function ·
Silicone bronze shift rail bushings,
which are replaceable ·
Input shaft bearing oilier ·
Lightest weight possible, only 4.25 lbs Fits all Porsche 901/911 69-71 and 914 70-76
magnesium case transmissions $399 |
