Twin Power 1966-1984 Harley-Davidson Shovelhead Big Twin Rocker Box Gasket Kit

Maintain the iconic performance of your Harley-Davidson Shovelhead Big Twin with this essential Rocker Box Gasket Kit from Twin Power. Covering models from 1966 to 1984, this kit provides the necessary gaskets to ensure a leak-free seal for your engine's rocker boxes, crucial for proper lubrication and operation.

  • Comprehensive Kit: Includes all required gaskets for a complete rocker box seal on your Shovelhead.
  • Broad Fitment: Designed for a wide range of 1966-1984 Harley-Davidson Big Twin models, including FLH, FX, FXE, FXEF, FXR, FXRS, FXRT, FXSB, and FXST.
  • Durable Materials: Made from high-quality materials engineered for longevity and resistance to oil and engine heat.
  • Direct Replacement: Ensures a precise fit and reliable sealing performance, meeting the needs of classic bike owners.
  • Prevent Oil Leaks: Effectively seals rocker boxes to keep your engine clean and running efficiently.
