Product Description
ARP 234-4300 High Performance Head Stud Kit
Fits 2003-Newer Gen III HEMI 5.7L, 6.1L, 6.2L & 6.4L Engines Including Hellcat
Upgrade the cylinder-head clamping hardware on a compatible Gen III HEMI engine with the ARP 234-4300 High Performance Head Stud Kit. These studs are manufactured from premium 8740 chromoly material with a rated tensile strength of 190,000 psi, providing a significant increase in clamping force compared with factory head bolts. Each stud is cold-forged and heat-treated before the threads are rolled to help maintain molecular integrity throughout the manufacturing process. The complete kit includes the required head studs, hardened washers, 12-point nuts and ARP assembly lubricant for compatible 2003-newer 5.7L, 6.1L, 6.2L and 6.4L Gen III HEMI engines, including Hellcat applications.
Key Features & Benefits
- Premium ARP 8740 Material: The head studs are manufactured from premium ARP 8740 chromoly material selected for demanding engine-fastener applications. This material provides the strength required to increase cylinder-head clamping force compared with the original factory head bolts.
- 190,000 PSI Tensile Strength: ARP rates the 8740 material used in this kit at 190,000 psi tensile strength. This specification makes the 234-4300 kit a performance-oriented cylinder-head fastening upgrade for compatible naturally aspirated and factory-supercharged Gen III HEMI engines.
- Controlled Manufacturing Process: Each stud is cold-forged and heat-treated before the threads are rolled. Completing these processes in this order helps preserve molecular integrity and produces the precisely formed threads expected from ARP performance engine fasteners.
- Complete Head Stud Hardware Kit: The kit includes the ARP head studs, hardened washers, 12-point nuts and assembly lubricant needed for the supplied fastening system. The 12-point nut design provides a compact, performance-focused hardware configuration for compatible Gen III HEMI cylinder heads.
- Broad Gen III HEMI Coverage: ARP part number 234-4300 fits compatible 2003-newer Gen III HEMI engines in 5.7L, 6.1L, 6.2L and 6.4L displacements. The supplied coverage also includes compatible 6.2L Hellcat engine applications.
