Pioneer Automotive Cylinder Head Bolt

Pioneer Automotive cylinder head bolt sets are replacement head bolts and cylinder head fasteners for engine rebuilds and repairs. Pioneer Automotive Industries has offered a line of engine fasteners for decades, and engine builders and professional remanufacturers have relied on it. The line covers a wide range of early and late model engine applications.

Key Features:

• Made to meet or exceed OEM specifications for dependable clamping of the cylinder head and head gasket
• Wide coverage of early and late model engine applications
• Replacement bolt kits are matched to specific engine applications, so you can choose the hardware recommended for your engine
• Suited to professional engine rebuilds and DIY repairs

Many late-model engines use torque-to-yield head bolts. These must be replaced whenever the cylinder head is removed, to help prevent premature head gasket failure. Fresh Pioneer head bolts help restore proper clamp load during reassembly.

Choose the individual part number that matches your engine application to get the correct hardware for your rebuild.
