CMS 997 BILLET SHIFT FORKS

(for Porsche 997 Carrera 2 and 4 manual 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.

$1050 per set of 3
