Product Details

ARP 125-4001 head studs are engineered for 1972-1976 Buick 455 V8 engines, providing superior cylinder head-to-block sealing in high-performance applications. These hex head studs are essential for engines running high compression pistons, turbochargers, superchargers, or nitrous oxide systems where maintaining proper head gasket seal is critical.

Premium Construction and Manufacturing Process:

  • Manufactured from premium grade 8740 chromoly alloy steel, superior to standard aircraft-quality materials
  • Precision heat-treated to 200,000 psi tensile strength for maximum clamping force
  • Centerless ground through approximately ten precise cuts for exceptional straightness and concentricity
  • Thread rolled after heat-treat for approximately 1,000% better fatigue strength compared to pre-heat-treat threading
  • Specially undercut shorter studs equalize stretch characteristics for consistent clamping force across all fasteners

Performance Benefits:

  • Exacting tolerances allow cylinder heads and gaskets to align perfectly during installation
  • Equalized stud stretch compensates for head gasket compression, preventing blown gaskets
  • Superior fatigue resistance ensures reliability in high-stress racing and performance applications
  • Hex head design provides secure installation and removal

Application:

  • 1972-1976 Buick Electra with 455 cubic inch V8 engine
  • Suitable for other Buick 455 applications from the same era

Awesome product And fast fishing

I ordered a WeatherTech cargo liner from Autoplicity after finding the product almost $40 cheaper than anywhere else. Usually I'm suspect of the one company with a very low price but the high number of reviews gave me enough comfort to order. The product came in a large box and was shipped for a very reasonable price and arrived in four business days. The product is as described and I couldn't be happier. I will definately keep them in mind for future orders.

Easy website to navigate

Fantastic prices and fast shipping!! Looks like I'm done with Jeg's and Summit!!

I am very pleased with my purchase from Autoplicity. Price was very reasonable and shipping was great!
