ARP 134-4001 Head Studs for Chevrolet Small Block (Hex)
- Brand: ARP
- Part Number: ARP-134-4001
- Country of Manufacture: United States
ARP Pro Series head studs are built for competition engines where consistent clamp load and repeatable service matter. ARP uses premium 8740 alloy and its proprietary ARP2000 alloy, heat-treated in vertical racks for controlled, even heat penetration—190,000 psi for 8740 material and 220,000 psi for ARP2000 material. Tight manufacturing tolerances and centerless-ground construction help gaskets and cylinder heads align cleanly during assembly.
Why use head studs
- Easier engine assembly with the head and gasket guided into proper alignment
- More accurate, consistent torque loading versus bolts (the nut is torqued while the stud remains on the vertical axis)
- Designed to be installed in a relaxed mode—hand tight rather than cranked in with a jam nut
Manufacturing notes
- Premium 8740 alloy and proprietary ARP2000 alloy
- Precisely heat-treated: 190,000 psi (8740) and 220,000 psi (ARP2000)
- Centerless-ground for consistent fit and alignment
