Supertech Dual Valve Spring & Retainer Kit - K Series
All Supertech valve springs are made with premium Superclean Chrome Silicon Vanadium Steel alloy for higher performance & durability at high RPMs. Using high-quality steel alloy also provides the added benefit of better structural memory for all of our springs.
Supertech retainers are manufactured with high-quality military certified Titanium alloy and are CNC machined for a tight fit. Our high-quality retainers are among the best in the industry.
These valve spring and retainer kits are ideally suited to high horsepower forced induction builds and high lift NA cam applications. Perfectly paired with Skunk2 Tuner or Ultra series cams.
DO NOT shortcut on cheap valvetrain or a “she’ll be right” attitude with your factory Honda gear. Even ITR valvetrain is not suitable for most engine builds.
