Description

Experience a dramatic increase in horsepower and torque with the S&S Cycle 128" Power Package, specifically designed for VVT models. This premium engine kit is engineered for a straightforward "bolt-in" installation, eliminating the need for complex case machining, making your upgrade process smoother and faster. At its core are durable forged pistons, meticulously crafted with an updated profile to withstand the extreme demands of high-performance riding, ensuring longevity and consistent power delivery. The package features a precision-machined billet aluminum oil pump/cam plate, designed with independent scavenge sections for both the flywheel cavity and camchest, significantly increasing oil flow capacity on both the feed and scavenge sides. Integrated debris screens and a strategically placed magnet in the camchest provide superior protection against contaminants, while the adjustable pressure relief valve allows for fine-tuning even after installation. The heart of this power upgrade is the renowned S&S 550 camshaft, paired with high-quality Quickee pushrods and S&S premium tappets. These tappets boast hard anodized, billet aluminum, black coated cuffs, providing exceptional stability for high-lift and high-RPM situations. Complementing the camshaft are robust valve springs, designed to work flawlessly with camshafts up to 0.605" lift, complete with top collars, keepers, valve seals, and bottom collars. Proudly made in the USA, this S&S Cycle 128" Power Package ensures top-tier quality and performance for your VVT model, though it is not compatible with any Trike models.
