SpeedFactory Racing 4140 Cylinder Head Stud Kits

The SpeedFactory Racing 4140 cylinder head stud kits are designed to provide superior clamping force, preventing cylinder head lift and head gasket failure in high-performance, forced induction (turbo/supercharged) Honda®/Acura® engines. The studs maintain a tight seal on the cylinder head under extreme boost, crucial for preventing combustion gases from escaping. The 4140 steel head studs resist stretching far better than OEM head bolts, essential for high-horsepower reliability. Each kit includes forged nuts and washers designed to distribute clamping loads evenly across the engine block. Select the kit for your application needs. Key features: * 210,000 psi tensile rating * Hex broach on the top of the stud for ease of installation and a dog point design for superior preload * Oversized forged 12-point nuts and hardened parallel ground washers for superior load distribution compared to smaller nuts and washers * Direct drop-in replacement for OEM head bolts * Studs feature a corrosion-resistant black oxide coating
