Tappet Blocks

45 products

Tappet Blocks for Harley-Davidson house the hydraulic or solid lifters that actuate your engine's valves, making them a fundamental component of the valve-train. Worn or damaged tappet blocks can cause noisy operation and uneven performance. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks tappet blocks from S&S, MCS and Jims for Big Twin, Sportster and Twin Cam applications. Whether you are upgrading to high-performance tappet blocks as part of a cam swap or replacing worn originals during an engine rebuild, these precision-machined components deliver reliable valve actuation across the full rev range.
