S&S 585GE Gear Drive: The 2026 Pinnacle of Twin Cam Valve Train Stability

The S&S Cycle 585GE Easy Start Gear Drive Cam Chest Kit for 2006-2017 Harley-Davidson Twin Cam models represents the 2026 peak of performance engineering for the late Twin Cam platform. For riders building a high-output 103″ or 110″ engine, the factory chain drive system introduces unwanted friction and timing harmonics. S&S addresses these 2026 concerns by replacing the chains with a precision-machined gear drive system. This provides secure, mechanical utility by locking in your valve timing with zero stretch or tensioner wear. The 585GE cams are optimized for mid-to-high RPM power, providing a massive 2026 boost for riders who enjoy aggressive highway pulls and canyon carving, while the mechanical synchronization of the Easy Start centrifugal weights ensures your starter motor never struggles against high compression.

Patented Easy Start Technology and Gear Drive Reliability

What sets the S&S 585GE kit apart in the 2026 marketplace is the integration of the patented **Easy Start** system. In the performance 2026 scene, high-lift cams often make starting a hot engine a mechanical nightmare; S&S solves this by using a spring-loaded pin that slightly vents compression at cranking speeds, then retracts once the engine fires. This results in a high-output 2026 presence that starts as easily as a stock bike but pulls like a race machine. By moving to a gear-to-gear drive, you eliminate the single most common failure point in the Twin Cam engine—the cam chain tensioners—providing an industrial-strength 2026 solution that offers peace of mind for the life of the motorcycle. Combined with the included S&S high-volume oil pump and cam plate, your engine will benefit from superior scavenging and reduced 2026 sumping risks.

Expert Installation & Performance Advice

As specialists in Twin Cam performance architecture, we recommend the 585GE Kit for any 2026 build with 10.0:1 to 10.5:1 compression. Pro Tip: Before installing gear drive cams, you MUST check your **crankshaft run-out**; it should be .003″ or less to ensure a secure, quiet 2026 gear mesh. Installation Note: This kit includes Quickee Pushrods, which allow you to install the cams without removing your 2026 rocker boxes, saving hours of labor. Maintenance Note: Use a high-quality 20w50 full synthetic oil to maintain the 2026 integrity of the gear teeth and high-flow oil galleries. Safety Note: Because this kit significantly increases engine volumetric efficiency, a **fuel management recalibration** (such as a Dynojet Power Vision) is mandatory to prevent lean conditions and ensure a secure, powerful 2026 ride.
