ARP Honda D16Y8 Cylinder Head Stud Kit
Heavy-duty cylinder head fastener upgrade engineered for high-boost, high-RPM Honda D-series engines.
Product Overview
When increasing power or boost on your Honda D16Y8 engine, factory head bolts can stretch, leading to head gasket lifting and severe engine damage. The ARP AR8608 Head Stud Kit provides exceptional clamping force to maintain a leak-free head seal under heavy combustion loads. Manufactured from premium 8740 chrome moly steel and heat-treated to 200,000 PSI, this stud kit is an essential upgrade for tuned street, track, and drag racing engines.
Key Features
- ☑ Precision machined from high-tensile 8740 chrome moly alloy
- ☑ Heat-treated to a 200,000 PSI tensile strength rating for maximum fatigue resistance
- ☑ Precision thread-rolled post heat-treatment for up to 10x fatigue strength
- ☑ Includes 12-point hex nuts and hardened parallel washers for equalized clamping force
- ☑ Prevents head gasket blowouts under extreme boost or high compression
