To obtain maximum power from your performance camshaft, it may be necessary to fit a set of vernier pulleys.
These ultra light dual units allow for simple, quick adjustment
The graded scale etched into the pulley allows you to advance or retard cam timing
However, going away from the recommended setting will often incur losses at some point in the rev range, fro this reason we recommend expert setup of these items.
The vernier pulleys feature a true vernier adjustment which will allow accurate timing adjustment down to one tenth of a degree.
Range of Colours available;
red, blue or black
please stipulate which colour you require when ordering
