Kuryakyn 1-1/4 inch Breather Bolts for Harley-Davidson Twin Cam Engines

Properly manage crankcase pressure in your Harley-Davidson Twin Cam engine with this pair of 1-1/4 inch Breather Bolts from Kuryakyn. These bolts are designed to replace the stock breather bolts, offering a more robust solution for venting excess pressure and moisture from the crankcase. Ensuring your engine breathes correctly is crucial for performance, longevity, and preventing oil leaks.

Key Features and Benefits:

  • Designed for Twin Cam: Specifically engineered for Harley-Davidson Twin Cam engines.
  • 1-1/4 inch Size: Provides adequate venting capacity for optimal crankcase pressure management.
  • Durable Construction: Made from high-quality materials for long-lasting performance and reliability.
  • Replaces Stock Bolts: Direct replacement for OEM breather bolts, ensuring proper fitment.
  • Promotes Engine Health: Helps vent moisture and pressure, reducing the risk of oil leaks and internal engine damage.
  • Easy Installation: Simple bolt-on upgrade that can be performed with basic tools.

Crankcase pressure can build up due to combustion blow-by and normal engine operation. If not properly vented, this pressure can force oil past seals and gaskets, leading to leaks and potential engine damage. Kuryakyn's breather bolts provide an effective solution by allowing these gases to escape. This pair ensures you have the necessary components to upgrade both sides of your engine's venting system.

Whether you're performing routine maintenance or a performance upgrade, these breather bolts are a valuable addition to your Harley-Davidson Twin Cam. Ensure your engine operates at its best by providing it with the proper ventilation it needs.
