Skunk2 is proud to introduce its Pro Series Timing Chain Tensioner for Honda’s K-series engines, making it safer than ever for K-series owners to take advantage of aggressive, aftermarket camshafts. Pro Series Tensioners are machined from high-quality 7075-aluminum, are heat-treated, and feature stiffer, OEM-quality springs that eliminate chain slack and prevent the exhaust camshaft from slamming shut at low engine speeds, even under low oil pressure conditions where the factory spring is normally compromised.

Pro Series Tensioners also include an upgraded 16mm diameter piston (1.5mm larger) with a larger ratcheting mechanism that features deeper and wider, hardened-steel ratcheting teeth for extra protection—the ultimate fail-safe to ensure against excessive tensioner piston travel and potential engine damage due to worn teeth. Pro Series Tensioners also fit tightly against the timing chain guide to ensure against rotational movement, which can exert uneven load against the ratcheting teeth. Even the factory-designed oil passages and check valves have been retained, which means Pro Series Tensioners remain lubricated and pressurized just as Honda intended.
