HKS Head Studs Kit G16E-GTS - 2023-2026 Toyota GR Corolla

Head Studs for High-Boost Cylinder Sealing
HKS head stud kits replace factory head bolts with studs and nuts that provide more consistent and higher clamping force on the head gasket. Head bolts apply combined tensile and torsional stress when torqued. Head studs isolate these loads -- the stud is installed hand-tight first, then the nut applies only tensile load, allowing higher clamping force without risk of shearing under combined stress.

Details

• Applies pure tensile load vs combined tensile and torsional stress of head bolts
• Maintains more consistent clamping force through sustained thermal cycling
• Allows higher clamping force without shear risk from combined stress loading
• Essential for reliable head gasket sealing at elevated boost and cylinder pressures
• Install with HKS Grommet Type or equivalent performance head gasket

Why Studs at High Boost
Higher clamping force consistency through thermal cycling is the key advantage of studs over bolts for high-boost applications. The nut-and-stud system maintains more predictable clamp load as the head and block expand and contract with temperature. For builds targeting serious power, head studs are non-negotiable for reliable head gasket retention.

Why Choose HKS
HKS has been engineering performance automotive components since 1973, building a global reputation through motorsport involvement at the highest levels of circuit racing, rally, drag, and time attack. Their product range covers virtually every aspect of engine and chassis performance, with each product developed through in-house testing and real-world validation on the specific vehicles it is designed for. For Subaru, Toyota, and Honda performance builds, HKS offers some of the most platform-specific aftermarket engineering available.

The RallySport Take

If the head is coming off for any reason, head studs should be part of the rebuild. For builds targeting serious power, they are non-negotiable. Install with the HKS Grommet Type head gasket for a properly specified sealing system.
