Piston Kit 80" Stock Big Twin

Upgrade your Harley-Davidson with our Piston Kit for 80" Stock Big Twin Motors. This premium kit is designed for those who demand superior performance and reliability.

  • 🔩 Forged Pistons: Crafted for superior strength, ensuring longevity and durability.
  • 🛠️ Complete Kit: Includes a set of pistons, rings, wristpins, and clips for a seamless installation.
  • 📏 Precision Engineering: Wrist pin deck height of 1.270" for optimal fit.
  • 🇺🇸 Made in the U.S.A.: Supporting American manufacturing.
  • ⚙️ Compatibility: Requires connecting rods with a rod length of 7.440" (standard length OEM #24281-74A). Using earlier connecting rods with a length of 7.470" (OEM # 24281-41A) may slightly increase compression ratio and could cause clearance issues.

Ensure your pistons fit perfectly by checking all piston to cylinder head clearances when using early-style rods.
