On a side note:
Skunk2 hand etches a “code” on their camshafts to identify what model they are and for authenticity. As seen here:
I have been informed by two Skunk2 representatives as well as tech support, stating:
“As of Feb 2011 we did change some of the markings on the cams to prevent people from selling skunk2 product that was not official. We are transitioning away from the hand etched markings on our camshafts and moving towards a stamp system.”
The new “code” is now a stamp seen here:
Skunk2 adding to the statement:
“The ‘M’ is the correct stamp for B Pro Stage 2 camshafts. Old Pro 2 etchings would include P2, P2+,P2V. From this point on all B pro Stage 2 camshafts will have M stamped in the end of each of the camshafts.”
There you have it. If you plan on purchasing a set of Skunk2 Pro series camshafts, that’s the stamp you will need to look for if your worried about authenticity. They also stated, to purchase their products from AUTHORIZED DISTRIBUTORS.
