S&S Tappet Blocks

10 products — part of all Tappet Blocks

S&S tappet blocks for Harley-Davidson provide precision-machined replacements for the lifter block assemblies that guide hydraulic tappets through the V-twin bottom end. The tappet block is a structural and precision component — it locates the tappet centrally on the cam lobe and supports correct lifter travel through the full lift cycle. Worn or poorly machined tappet blocks introduce side loading, accelerate tappet body wear and create the oil leaks that develop at the tappet block gasket face over time. S&S Cycle machines their Harley-Davidson tappet blocks to tighter bore concentricity than the factory casting, delivering quieter operation and longer tappet service life across Shovelhead, Evolution and Twin Cam Big Twin applications. Iron City Motorcycles, your authorised Harley-Davidson dealer in Leeds, stocks S&S tappet blocks as part of a comprehensive bottom-end rebuild programme. Browse the full S&S Tappet Blocks range below.
