Description

Up to 80 hp gains with Skunk2's Ultra Series line of camshafts, our professional line of high-lift, racing camshafts for Honda's K-series VTEC engines. Ultra Camshafts are designed to optimize mid-range and top-end horsepower and torque, with peak power moved up the RPM band. As a result, VTEC crossover is seamless, allowing for the broadest powerband possible. No other line of racing camshafts even comes close to Skunk2's Ultra Series. Whats more, Ultra Camshafts are also the perfect addition to any high-output, turbocharged engine. Skunk2's Ultra Series Camshafts for Honda's K-series engines dramatically increase both horsepower and torque yet retain complete valvetrain stability and exceptional engine response. Ideal for heavily modified engines, Ultra Series Camshafts are manufactured from proprietary, high-quality forged tool steel cores, are CNC ground, and feature patent-pending profiles with unique lobe shapes and revolutionary lift, velocity, and acceleration characteristics. 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. Each camshaft is manufactured of forged tool steel core, 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's Ultra Series Camshafts also feature Fast Ramp and AMAX profile technology, which increases overall performance and results in unmatched response from idle to redline.
