ALBINS 996 BILLET SHIFT FORKS (NOT INCL BOXSTER S 986) The original forks are cast and sometimes break or
will simply wear out. The roll pin provisions are also known to wear
out causing failure. Billet forks are stronger, more reliable and are
commonly used in factory race transmissions. ·

ALBINS 996 & BOXSTER S 986 SHORT/CLOSE RATIO
GEAR KIT 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 that there
has been a gain in power. Alternative
gear ratios can make the car more fun to drive or be more drivable. We offer a short/close ratio gear kit that replaces
the stock 3rd-6th gears greatly reducing the RPM drops
from 2nd to 6th allowing you to better stay on the cam. Short/close ratio gear kit consisting of 3rd-6th
gear sets and conversion steel cage bearing assembly $3875 ·

CMS 996 & BOXSTER S 986 SHIFT ARRESTER If you are unfortunate enough to experience the
dreaded 2nd gear pop out, DON’T GRIND YOUR TEETH! After extensive testing and development we are proud
to announce a new component related to the internal shift mechanism that
promotes far better and more reliable engagement to 2nd gear with
a newly designed profile. This will allow for a more proper engagement of the
synchro teeth and will not result in any unwanted changes to other critical
settings unlike backyard “modifications” do. Precision machined from 4130 Chromoly steel. $199 Installation instructions

CMS 996 & BOXSTER S 986 INTERNAL OILING SYSTEM The internal components of your Carrera or Boxster S
gearbox can be better lubricated, especially on the input shaft where parts are
farthest away from the oil. Under
certain conditions the transaxle may experience oil starvation, a
contributing factor for overheating often resulting in costly damage or
failure. CMS now offers “prepared” input shafts and bearing races
with oil passageways to 3rd through 6th gear bearing
journals, similar to Turbo, GT2 and GT3 transmissions. It will be necessary that oil out (suction) and in
(return) ports are fitted to the appropriate locations on the transmission
case and requires an external remote electric pump to be installed-preferably
with a cooler and filter. The benefits to doing all this are tremendous and
will promote lubrication, cooling and thus longevity. Parts are available exchange and outright, used and
new. Contact
us for further information and pricing. |

CMS 996 & BOXSTER S 986 BILLET 3RD/6TH
GEAR MAIN SHAFT THRUST WASHER It’s not uncommon for the original thrust washer to
fail causing serious damage inside your transmission. We now offer a stronger billet thrust
washer; one that actually promotes lubrication to 3rd and 6th
gear needle cage bearings. $120 |
