Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Engine Lifters and Parts

  • Compatibility: Ensure lifters match your Harley's engine type (e.g., Milwaukee-Eight M8, Twin Cam, Evolution, Big Twin/XL) and model (e.g., Twin Cam 1999-2017, M8 2017+). Use the vehicle selector for year-specific fits to avoid valvetrain noise or performance issues.
  • Type of Use: For stock or street riding, choose hydraulic lifters for quiet operation; high-RPM or race applications benefit from race series or solid lifters for durability and support with aggressive cams.
  • Components and Upgrades: Select hydraulic (full/short-travel), solid, or tappet options; upgrade to race series with roller designs or oversize tappets (+0.002"/+0.005") for enhanced lubrication and stability.
  • Brand and Quality: Opt for Feuling Oil Pump Corp. for Race Series and HP+ lifters with machined steel and billet bodies, JIMS for PowerGlide and Hydrosolid tappets, or Eastern Motorcycle Parts for standard tappets. Prioritize USA-made precision-ground CNC materials for reliability and reduced noise.
  • Installation and Cost: Most are bolt-in with adjustable preload; sets of 4 for lifters, individual for tappets. Prices range from $114.95 for standard tappets to $319.95 for race series sets—factor in same-day shipping and free shipping over $99 for value.

Frequently Asked Questions (FAQs)

  1. What Harley models and engines do these lifters and parts support? Parts support Milwaukee-Eight M8, Twin Cam (1999-2017), Evolution (1984-1999), Big Twin/XL—use the year/make/model filter for exact compatibility with intake/exhaust positions.
  2. How do race series lifters improve performance? They offer high-RPM durability, slower bleed-down for large-lift cams, and optimized oiling to reduce noise and extend valvetrain life.
  3. What is typically included in a lifter set? Sets of 4 lifters; tappets sold individually with options for standard preload or oversize diameters.
  4. Are these lifters suitable for high-spring pressures? Yes, short-travel variants handle higher pressures and extended oiling intervals without sacrificing performance.
  5. What if a part doesn't fit my Harley? Verify engine type, riding style (street/race), and size (standard/oversize) before buying. Our returns policy allows exchanges or refunds if it doesn't match.
  6. Can I find related engine parts? Yes—explore cams, pushrods, or valves in the Harley engine category to complement your lifters upgrade for a full valvetrain refresh.

Big Power, Nice Sound!

Picked up a Pro Circuit pipe and silencer for my YZ125 it’s a game changer. The power feels way better and the sound is awesome.

Helps keep cool, works great!

Bought the dual pass Allstar radiator for my build, and it’s been solid. Keeps the engine running cool even on the hottest days no complaints here!
