CMS 997 BILLET SHIFT FORKS

(FITS ALL 997 CARRERA 2 AND 4 TRANSMISSIONS)

 

The original cast forks use plastic pads with only 2 areas of contact to the shift sleeve.  Our new racing forks are machined from billet aluminum so they are much stronger.  The “pads” are now incorporated to the design and area of contact to the shift sleeve increased.  Now there is no plastic to fail and you can expect a more reliable shift.

 

It is not uncommon for a car to have a transmission replaced because of a pad failure.

 

$1050 per set of 3

CMS BILLET CABLE SHIFTER/SHORT SHIFTER

(Designed for use with G50 cable shift converted transmissions and all factory cable shift transmissions)

 

Modeled after the Porsche 996 cable shifter, our assembly incorporates a B&M standard issue short shifter (45135).

 

Additionally, depending on which base plate is installed, the CMS billet cable shifter will accommodate either custom made to order shift cables or factory shift cables.  The nature of the application will best determine which base plate and cable combo is best.

 

Other features include:

  • A 35% reduction in throw
  • Side to side free play is eliminated as found in OEM shifters
  • All of our parts are precision machined from billet 6061-absolutely no parts are stamped or cast

 

CMS billet cable shifter assembly with B&M 45135 short shifter installed $849

 

The shifter can be ordered without the B&M shifter, if you already have one.

NEW PRODUCT RELEASE

CMS SHIFT ARRESTER

 

ATTENTION - 996, BOXSTER S, 996T, GT2 AND GT3 OWNERS:

 

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.
