These camshafts from V-Thunder provide the ultimate in arm stretching power on the street or in competition. Power proven and backed by hundreds of exhaustive hours on the dyno and in on-bike testing, these cams provide added punch at all levels of performance for Evolution and Shovelhead motors, while maintaining the longevity and integrity of the valve train parts. Cams that need a Hi-Performance carburetor were found to give the best performance with the Mikuni's HRS42 carburetor. V-Thunder cams are made with SAE 6150 bearing, quality steel and induction hardened for optimum surface longevity. Tolerances are extremely precise with the aid of our computer controlled machining centers. The cams are made in the USA and come with complete installation instructions.

Recommended Retail Prices include 20% sales tax.

Prices exclude shipping, import duties and installation.

Prices are based on EUR to GBP interbank rates obtained daily. The interbank rate is the rate that banks trade currency to each other. These prices must be used as a guide.

Note: 1970 thru early 1977 cams and late 1977 thru 1984 are not interchangeable as they have a different tooth pattern. To help you to identify what you need: early style cams have a flat gear, late style cams feature a groove in that gear on the ignition side.
