Product Details

Moroso Chrome Moly Head Bolt Washers are hardened washers for cylinder head bolts and studs. They help spread clamping load evenly across the cylinder head surface. This supports a consistent seal in street performance, drag racing, circle track and other high-load engine builds. Use them with head bolts, head studs or nuts that need a smooth, hard bearing surface.

Key Features:

  • Chrome moly steel construction for strength and durability under high clamping loads
  • Hardened bearing surface that resists galling and surface deformation when fasteners are torqued
  • Even load distribution across the cylinder head to help maintain head gasket sealing
  • Suited to performance engines that see high cylinder pressure, boost or nitrous
  • Multiple sizes available to match different head bolt and stud applications

Moroso has built racing and performance engine components for decades. These washers are a dependable addition to a cylinder head installation or engine rebuild. Always follow the engine builder's and fastener manufacturer's torque specifications and lubrication recommendations.
