First introduced in 1999, Tuner Series Camshafts are manufactured from the same proprietary, high-quality cores as Skunk2’s more aggressive Pro Series Camshafts, are CNC ground, and feature unique profiles and lobe shapes that emphasize an exceptional idle and low emissions.

Skunk2 camshafts deliver unparalleled power as a result of continual, extensive development and testing. By utilizing advanced manufacturing techniques and the latest computerized simulation and modeling equipment, Skunk2 camshafts are able to deliver maximum power across the entire powerband.

⚙ Expected Performance Gains

With proper setup and tune:

• Stronger mid-to-top-end power

• Noticeable VTEC hit

• Improved high RPM breathing

• More aggressive powerband

B-series engines love airflow. This cam gives them more.

🔩 Skunk2 B Series Stage 2 Camshaft Installation Notes

• Degree cams properly (don’t eyeball timing marks)

• Check piston-to-valve clearance

• Verify installed spring height

• Tune immediately after install

Guessing cam timing is how you bend valves.

Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance. Each camshaft is manufactured of newly revised chill-cast, billet camshaft blanks that have increased torsional strength, improved durability characteristics, and reduced frictional effects. All Skunk2 camshafts are ground to exact specifications using state-of-the-art CNC cam grinding machines equipped with cubic-boron grinding wheels and feature hardened, wear-resistant lobes and surfaces.

Skunk2 camshafts designs are the direct result of our years of drag racing and road racing efforts. In addition to each Skunk2 project car and race vehicle, the world’s top road racing and drag racing teams have relied on Skunk2 camshafts for years.
