All-Around Powerhouse: S&S Cycle 510 Cam Kit for Harley Twin Cam (2006–2017)

The S&S Cycle 510 Cam Kit stands as a benchmark in performance upgrades, specifically designed to unlock the true potential of the later-model Harley-Davidson Twin Cam engines (2006–2017). This highly versatile camshaft is engineered to provide an aggressive, yet streetable, power curve that delivers significant increases in both horsepower and torque across the entire RPM range, with a strong focus on the mid-to-upper end. It is widely considered one of the best choices for riders seeking maximum all-around performance from their 96ci, 103ci, or 110ci Twin Cam.
Engineering for Wide-Band Performance

The S&S 510 Cam is specifically tailored for the 2006-2017 engine architecture, which utilizes a different rod length (in the Dyna), revised crankcases, and hydraulic cam chain tensioners (2007-later models). The cam’s grind is optimized to dramatically improve volumetric efficiency over the stock cam, yielding power that is both immediate and sustained.
True Bolt-In Design (Hydraulic Tensioners)

For the 2007–2017 models with hydraulic cam chain tensioners, the S&S 510 Cam is a true bolt-in cam for Twin Cam 96/103 engines. The lift of 0.510″ is generally compatible with the stock valve springs and heads, eliminating the need for costly head work. This makes the Twin Cam 510 Camshaft Upgrade one of the most cost-effective ways to realize substantial power gains on these later model engines.
Kit Composition and Reliability

S&S Cycle ensures that their performance kits provide durability alongside power. The S&S Cycle 510 Cam Kit often includes all necessary components for a clean installation:

510 Cams: Precision-ground cams.

Inner Cam Bearings: New inner cam bearings are a mandatory replacement item for any cam swap.

High-Performance Pushrods: Adjustable pushrods (recommended or included) allow for precise setting of tappet preload, ensuring quiet operation and maximum lifter longevity.

Gasket and Hardware Kit: All required seals and gaskets for the cam chest area.

The reliability of the S&S 510 Cam is further enhanced when paired with high-quality S&S tappets/lifters, which are designed to handle the increased velocity and pressures associated with the aggressive cam profile.
Essential Performance Add-ons

While the cam itself is straightforward, maximizing the power potential of the Harley Twin Cam Performance Cam 2007-2017 requires these critical supporting components:

Tuning is Mandatory: The engine’s fueling requirements change dramatically with this cam. A proper EFI tuner and a professional dyno tune are non-negotiable to maintain engine health and achieve optimal power.

Air and Exhaust Flow: A high-flow air cleaner and a performance exhaust system are essential. The 0.510″ lift is moving significantly more air, and the engine must be able to ingest and expel that volume efficiently. A 2-into-1 exhaust is often the best choice for capitalizing on the cam’s strong mid-range and top-end performance.

The S&S Cycle 510 Cam Kit is the ideal solution for the rider seeking a powerful, high-performance Twin Cam Performance Cam that delivers an exhilarating top-end rush while maintaining excellent street manners.
