Gain an extra 20-25 hp with Skunk2 Pro 2+ Camshafts, our professional line of high-lift, racing camshafts for Honda&rsquos B16/ B17/ B18 VTEC engines. Pro 2+ Camshafts are designed to optimize mid-range and top-end horsepower and torque, raising peak power 700 rpm higher than what OEM or Pro 1+ Camshafts allow for. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2 Pro Series.

🔧 What a Skunk2 Pro 2 B Series Camshaft Delivers

Compared to Tuner Series Stage 2:

• More aggressive lift

• Increased duration

• Stronger high-RPM airflow

• More pronounced VTEC crossover

Designed for engines revving 8,000–8,800+ RPM.

Skunk2 Pro Series Camshafts for Honda&rsquos B-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Pro Series Camshafts are manufactured from proprietary, high-quality cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics.

🏁 Required Supporting Mods (Mandatory)

✔ Dual valve springs (race-grade)
✔ Upgraded retainers (steel or titanium)
✔ Adjustable cam gears
✔ Ported cylinder head
✔ High compression pistons recommended
✔ ECU tuning (Hondata / standalone)

Install these on stock springs and you’re flirting with valve float.

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. Skunk2 designs and tests all of its camshafts in-house to ensure the highest quality and performance.

⚙ Ideal Build Scenarios

• 220–240+ HP naturally aspirated B-series

• High compression street/strip builds

• Road race applications

• Fully built bottom-end setups

If you’re building for peak power and dyno numbers, this cam belongs in the conversation.

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&rsquos Pro Series Camshafts also feature Fast Ramp and AMAX profile technology, which increases overall performance and results in unmatched response
