Buying Guide and FAQs

Buying Guide: Factors to Consider When Choosing Harley Bike Engine Rings Only

  • Compatibility: Ensure rings match your Harley's engine type (e.g., Big Twin, Twin Cam, Evo, M8) and bore size (standard or oversize +0.005/+0.010/+0.020). Use the vehicle selector for model-specific fits to avoid compression loss or rebuild issues.
  • Type of Use: For standard rebuilds, choose moly-faced rings for quick seating; high-performance engines benefit from plasma-moly or low-tension rings for reduced friction and better power in demanding conditions.
  • Components and Upgrades: Select ring sets for one piston (top, second, oil rings); upgrade to oversize for bored engines or gapless designs for improved sealing.
  • Brand and Quality: Opt for Wiseco or Hastings for high-quality moly-faced rings with precise tolerances. Prioritize materials like cast iron or steel for durability and compatibility with forged pistons.
  • Installation and Cost: Rings are part of DIY piston installs with basic tools; prices range from $20 for basic sets to $50 for premium oversize—factor in free shipping over $99 and expert support for value.

  6. Can I find related engine parts? Yes—explore pistons, gaskets, cylinders/heads, or full kits in the Harley engine category to complement your rings for a complete rebuild.

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!
