billet shifter 12.gif

CMS BILLET CABLE SHIFTER/SHORT SHIFTER

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

Modeled after the Porsche 996 cable shifter, our assembly incorporates a B&M standard issue short shifter (45135). It’s conceivable that other shift kits can be installed as well. We have not verified this however.

Additionally, depending on which base plate is installed, the CMS billet cable shifter will accommodate either custom made to order (2” or 3” throw) shift cables OR factory shift cables (e.g. 996). 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 parts (minus B&M’s parts) are precision machined from billet 6061-no parts are stamped or cast

CMS billet cable shifter assembly with B&M 45143 (comes with plastic B&M shift knob) $849

The shifter can be ordered without the B&M shifter too.
