S&S Cycle 585C Standard Chain Drive Cam Chest Kit For Harley Twin Cam 2006-2017

S&S 585C Cam Chest Kit: The Definitive 2026 Twin Cam Performance Standard

The S&S Cycle 585C Standard Chain Drive Cam Chest Kit for 2006-2017 Harley-Davidson Twin Cam models represents the 2026 pinnacle of valvetrain and lubrication engineering. For riders of the 96″, 103″, or 110″ Twin Cam engines, the cam chest is the heart of the motorcycle’s performance. The 585C (Chain Drive) camshaft is specifically designed for engines with 10.0:1 to 10.5:1 compression, offering a violent increase in acceleration once the engine crosses the 3,500 RPM threshold. By replacing the stock, often-restrictive oiling system and cast cam plate with S&S’s premium components, you ensure that your engine can handle the aggressive ramp speeds of a high-lift cam. For the rider seeking secure, industrial-strength utility and a power profile that truly wakes up the Twin Cam platform, the 585C Cam Chest Kit is the definitive 2026 solution.

Integrated Lubrication and Structural Rigidity

What sets the S&S Cam Chest Kit apart in the 2026 marketplace is the synergy between its components. The kit includes the S&S high-volume oil pump and billet cam plate. The oil pump provides significantly more pressure and return-side scavenging than the factory unit, which is critical for maintaining hydraulic lifter stability and cooling the piston skirts during intense 2026 summer riding. The cam plate is CNC-machined from 6061-T6 billet aluminum, offering far more structural rigidity than the stock cast plate. This prevents the plate from “flexing” under the high spring pressures required for .585″ lift, ensuring the high-output 2026 presence and mechanical synchronization that professional engine builders demand. This kit doesn’t just add power; it builds a more robust engine from the inside out.

Expert Installation & Performance Advice

As specialists in Twin Cam valvetrain architecture, we recommend the 585C kit for any 2026 build aiming for triple-digit horsepower. Pro Tip: To truly maximize the .585″ lift of these cams, pair them with S&S Quickee Pushrods to save time on the installation. Installation Note: Always check your valve-spring-to-seal clearance and coil bind, as the .585″ lift exceeds the capacity of some early stock springs. Maintenance Note: Use a high-quality 20W-50 synthetic oil and a fresh filter during the 2026 break-in period to protect the new cam lobes and lifter rollers. Safety Note: Upgrading to a 585C cam requires an immediate ECU recalibration via Dynojet Power Vision to ensure your 2026 engine receives the correct fuel and spark timing to prevent detonation.
