TFS Billet Steel 2V, 3V, & 4V Adjustable Crankshaft Gears

 TFS Billet Steel 2V, 3V, & 4V Adjustable Crankshaft Gears

These Adjustable Crankshaft Gears allow easy 2, 4, 6, and 8 degree movements in cam timing in both retard and advance. 2 separate gears allow individual movement of each camshaft.

Install Tips:

• Spacer (included) is to be used with the newer style Stamped Steel Trigger Wheel
• Spacer is NOT used when installing with Accufab or older OEM Cast Trigger Wheel.

Order of installation:

• TFS Billet Adjustable Crank Gears
• TFS's supplied Spacer (only used with Stamped Steel Trigger Wheel)
• Trigger Wheel (make sure teeth are facing outwards)
• Timing Cover

**Due to the Crankshaft Keyway design, we recommend pinning these gears together once camshaft timing has been adjusted. If you are purchasing these gears for use with our Camshaft Degree Service, we will pin them together for you. We use two solid Hardened Steel 1/8" Diameter Pins.
