S&S HPT 560 Cam Chest Kit for 2023-2026 Harley M8 VVT - Chrome

Product Description

S&S Cycle HPT 560 Cam Chest Kit for 2023-2026 H-D M8 Models with VVT

Complete cam chest upgrade package engineered to unlock serious power and reliability from 2023-current Harley-Davidson Milwaukee-Eight models with Variable Valve Timing. The HPT560 is a bolt-in replacement cam built from high-strength billet 8620 steel with aggressive lobe profiles that deliver up to 24 horsepower and 14 lb-ft of torque over stock when paired with S&S Cycle intake and exhaust systems. Complete kit includes the HPT560 chain drive cam, Quickee adjustable pushrods with on-bike adjustment capability and no rocker box removal required, hand-assembled S&S precision tappets with tight tolerances for reduced valvetrain noise and superior high RPM performance, hard-anodized billet aluminum tappet cuffs optimized for high-lift and high-RPM operation, and a precision CNC-machined billet aluminum oil pump and cam plate. The oil pump delivers 44 percent more oil flow and 58 percent better scavenging efficiency with independent circulation sections for flywheel cavity and cam chest. Features dual debris screens, magnetic pickup for superior filtration, removable passage plugs for easy servicing, and an adjustable pressure relief valve that's tunable while installed. Includes S&S High Performance cam chain tensioner. Direct bolt-in installation with no custom grinding, no timing adjustments, and full compatibility with stock valvetrain and S&S rocker arm upgrades. Chrome pushrod tube option available.

Why Upgrade?

Stock M8 cam chests are engineered for compliance, not performance. You're leaving power on the table and reliability at risk. The HPT560 kit solves both problems with a complete package designed by engineers who understand high-performance Milwaukee-Eight dynamics. Up to 24 horsepower is real power you feel instantly, especially off the line and through the midrange. That 14 lb-ft torque bump isn't theoretical; it's noticeable snarl and pulling power. Billet 8620 steel is what Screamin' Eagle uses, not cast material. The aggressive lobe profiles are computer-optimized for maximum lift and duration without sacrificing reliability. The Quickee pushrods adjust on the bike without pulling rocker boxes, meaning fine-tuning takes minutes instead of hours. Hand-assembled S&S tappets come in at tolerances so tight they reduce valvetrain noise, kill vibration, and maximize high RPM stability. Hard-anodized billet tappet cuffs prevent distortion even under extreme conditions. The oil pump is the unsung hero here. Stock oil systems weren't engineered for aggressive cam profiles and high RPM operation. Forty-four percent more flow and fifty-eight percent better scavenging keeps your bottom end healthy under extreme conditions. Dual debris screens and magnetic pickup mean you're not inhaling wear particles. Independent scavenging for the flywheel cavity and cam chest prevents cavitation and keeps oil pressure stable. Removable passage plugs make servicing easy without complete disassembly. Chrome pushrod tubes add that finished look while delivering reliability. Direct bolt-in installation means zero guesswork. No custom grinding, no timing adjustments, install it and run. This is the complete solution for builders who want serious, reliable power.
