Heavy Duty Fasteners are one of the most vital engine component s for high performance and racing use. Replacing existing original fasteners improves clamp load and can prevent cylinder head and crankshaft movement. Additionally, many of the original fasteners used on the YD are torque to yield, single use type. Installing previously torqued hardware can lead to catastrophic engine failure. As some racing classes dictate original hardware is used, we offer the items that typically need replacing during a routine engine build.
