You can accurately alter your cam timing by 1°, 2°, or even 5°.

Get the right times with STR adjustable cam gears. STR has gone into great detail to create an adjustable cam gear that is second to none. Our gears are CNC machined from 6061-billet aluminum. The three windows are cut for lighter weight and balance. We've also drilled holes through the teeth for lighter weight as well as cooling properties. All load-baring edges are radiused for maximum strength. STR gears are superior in design, Dyno tested and most importantly, race proven. *When ordering insert "B" for blue, "C" for clear or "R" for red, "Y" for yellow after part number to indicate color desired.
