About S&S Cycle

S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.

Unleash the full potential of your Harley-Davidson engine with the S&S Cycle Performance Cam Plate and Oil Pump Kit. This upgrade is crucial for riders pushing their V-twin to the limit, ensuring optimal oiling under demanding conditions. Built from billet aluminum, it's designed to support high-RPM and high-performance applications.

Why riders pick this

  • 20% more oil supply flow for engine longevity
  • 52% more oil scavenge to prevent sumping
  • Billet aluminum construction for strength
  • Adjustable pressure relief valve
  • Independent scavenge for flywheel and cam chest
  • Debris screens in scavenge pickups

When you're building a performance V-twin, the oiling system is often overlooked, but it's critical for reliability and power. The S&S Cycle Cam Plate and Oil Pump Kit is engineered to deliver superior oil flow and scavenging, supporting the increased demands of modified Harley-Davidson engines. Its robust billet aluminum construction means it's built to last, providing peace of mind whether you're on the street or the strip.

Engineered for Maximum Oil Flow and Scavenge

  • Increases oil supply flow to critical engine components
  • Boosts oil scavenge capacity to prevent sumping
  • Adjustable pressure relief valve for in-engine tuning
  • Independent scavenge sections for optimal oil management
  • Integrated magnet in cam chest to capture metallic debris

Reliability for High-Performance Builds

This cam plate and oil pump kit is a foundational upgrade for any serious Harley-Davidson performance build. The independent scavenge circuits for the flywheel cavity and cam chest ensure efficient oil return, while the removable passage plugs simplify servicing. Pair this with a high-performance cam and lifters to build a V-twin that makes power reliably, mile after mile.

Currently in the process of the engine rebuild and it is not complete. Received the incorrect oil pump and I returned it for exchange. No problems with the exchange and a quick turn around for the exchange.
