skunk2 ULTRA STAGE 2 Camshafts (2016-2021 Honda Civic Si)

Skunk2 Ultra Camshafts for the L15B7 were designed to unleash the power potential of the Honda L15B7 engines. To ensure durability and precision, Skunk2 Ultra camshafts are machined from forged 8660 steel alloy blanks, induction hardened, and CNC precision ground. Ultra lobe profiles are designed in-house utilizing advanced simulation / CAD modeling techniques, and performance is validated on the dynamometer.

Skunk2 Ultra Stage 2 Camshafts for the L15B7 are designed as a street/strip cam that begins to make power after 3500rpm. Torque steadily increases from 3500rpm to a maximum gain of +30lb-ft at 4800rpm, and then holds +20lb-ft gain all the way to redline. Horsepower reaches a peak gain of +30hp from 5600rpm to redline. Stage2 cams require high-lift valve springs.
