Piper Cams Vernier Pulleys

Be the first to write a review

Correct camshaft timing can gain several horsepower even on a standard engine and substantially more on an upgraded engine.

To obtain maximum power from your camshafts, it will be necessary to fit a pair of our vernier pulleys.

These ultra light duraluminum units allow for simple, quick adjustment and the graded scale etched into the pulley allows you to advance or retard the cam timing to achieve the best torque / power characteristics of the engine.

These can be used on your standard camshafts or our upgraded Piper Camshafts.

See our Cambelts and Camshafts pages.

Sold in pairs (2 Pulleys).
