Kuryakyn has been the leading aftermarket V-twin parts brand since 1989 — chrome and black accessories for Harley-Davidson and Indian Motorcycle. From the iconic ISO grips to LED highway pegs and bagger upgrades.
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.
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.
Get your Kuryakyn 1-1/4 inch Breather Bolts today at GGCRACING and keep your Twin Cam running strong.
