Buying Guide and FAQs
Buying Guide: Factors to Consider When Choosing Harley Bike Cams and Parts
- Compatibility: Match cams to your Harley's engine (Twin Cam 1999-2017, Milwaukee-Eight M8 107/114/117", Evolution Big Twin 1984-1999, Sportster, Shovelhead). Use the vehicle selector for year-specific fits, including bolt-in vs. race grinds and compatibility with stock valve springs or fuel injection.
- Type of Use: For street/touring or low-end torque, choose bolt-in cams (e.g., Andrews N6, M450); high-performance or drag racing benefits from race series cams (e.g., Feuling 630/538 Series) for mid-to-top-end power gains up to 6000+ RPM.
- Components and Upgrades: Select individual cams, complete cam kits (cams + lifters + bearings + gaskets), gear drive kits, timing chains, or sprockets. Focus on features like high-lift lobes, aggressive grinds, and complete kits for easier installation and optimal performance.
- Brand and Quality: Choose Andrews for proven bolt-in street cams or Feuling for race series and gear drive options. Prioritize USA-made, dyno-proven designs with modern lobe profiles for smooth power, reliability, and maximum torque/HP gains.
- Installation and Cost: Many are bolt-in with stock valve springs; race cams may require upgraded springs/pushrods. Prices range from $269 for single cams to $2,050 for complete race kits—factor in expert fitment advice and free shipping over $99.
Frequently Asked Questions (FAQs)
- What Harley models do these cams and parts support? Supported models include Twin Cam (1999-2017), Milwaukee-Eight M8 (107/114/117"), Evolution Big Twin (1984-1999), Sportster, and Shovelhead—use the year/make/model filter for exact compatibility.
- How do performance cams improve riding? They deliver dyno-proven torque gains, smoother power delivery, and higher RPM capability (e.g., Feuling 630 Series runs strong to 6900+ RPM) while maintaining low-end drivability.
- Bolt-in vs. race cams: What's the difference? Bolt-in cams (e.g., Andrews M450, N6) use stock valve springs and are easy to install; race series (e.g., Feuling 538/630) require upgraded springs/pushrods for maximum high-RPM power.
- What is included in a complete cam kit? Most kits include cams, lifters, bearings, gaskets, and sometimes timing components—check details for specific inclusions like Feuling Race Series kits.
- What if a cam doesn't fit my Harley? Verify engine type, year, and grind requirements before buying. Our returns policy allows exchanges or refunds if it doesn't match.
- Can I find related engine parts? Yes—explore lifters, pushrods, timing chains, gear drive kits, or full rebuild components in the Harley engine category to complete your cam upgrade.
