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 more power from your Harley-Davidson Dyna with S&S Cycle Easy Camshafts. These bolt-in cams are designed to boost mid-range and top-end performance, making them an ideal upgrade for riders seeking noticeable gains without extensive engine modifications. They offer an accessible entry into serious engine tuning.

Common questions
Will these cams fit my specific Dyna model?
These cams are designed for 2006 Dyna models and all 2007-up Harley-Davidson big-twin engines. Please use our Shop by Bike tool to confirm exact fitment for your motorcycle.
Do I need other parts to install these camshafts?
These cams are designed to reuse many stock drivetrain components. However, a complete installation kit including gearcover gasket, bearings, and hardware is supplied, making it a comprehensive package.
Will I need to get my bike dyno-tuned after installing these cams?
Any camshaft upgrade alters engine characteristics significantly. A dyno tune is highly recommended to optimize fuel mapping and ignition timing, ensuring you get the most power and reliability from your new S&S cams.

I originally ordered the andrews H48 but while waiting for my thundermax tuner to arrive, I decided I wanted a big bore kit as well my bike has always been hard to start hot and I don’t have compression release heads so I got s&s mr 103 easy start cams and an S&s 107 big bore kit. I have not had a chance to ride it yet because after 4 weeks of waiting jp informed me it was gonna be 2 more weeks before the tuner would arrive so I had to cancel my order and ordered one from Fuel Moto yesterday, I have started the bike but have not rode it yet but it starts and restarts easy the cams work great!
