S&S Head Bolts

5 products — part of all Head Bolts

S&S head bolts for Harley-Davidson are specified for the additional thermal and mechanical loads of S&S performance engine builds — the fasteners holding cylinder heads onto big-bore and stroker engines where combustion pressures exceed OEM design parameters. S&S understand that the correct bolt torque, thread engagement, and material grade for an 88-inch Evolution are not the same requirements as a 107-inch or 117-inch V-series engine operating at elevated compression ratios. S&S supply head bolt kits dimensioned and graded for the specific cylinder deck height and thread engagement geometry of their supported engine configurations. Iron City Motorcycles stocks S&S head bolts for the Harley-Davidson performance build that demands fasteners engineered for the power levels being developed.
