Maximum Clamping Force for Mopar B/RB

For the ultimate in engine reliability, choose this Auto Racing Products 12-point head stud kit for your Mopar B or RB-Series engine. The 12-point nut design provides a higher torque capacity and a more secure fit than standard 6-point nuts, making them the preferred choice for high-horsepower and forced-induction applications. Manufactured from premium 8740 chromoly steel, these studs are heat-treated to ensure maximum tensile strength and fatigue resistance.

Technical Specifications

  • Material: 8740 Chromoly Steel
  • Finish: Black Oxide
  • Nut Style: 12-Point for superior torque handling
  • Application: Mopar B and RB-Series engines
  • Kit Includes: Full set of studs, 12-point nuts, and hardened washers

The 12-point design allows for a more compact nut profile, which is ideal for tight clearances around the cylinder head. These studs provide a consistent and even clamping force, which is vital for maintaining a perfect seal under extreme conditions. By replacing your stock bolts with this high-strength stud kit, you significantly reduce the risk of head gasket failure and improve the overall structural integrity of your engine. The black oxide finish provides excellent rust protection, ensuring these studs remain in top condition for years to come. Whether you are building a high-compression street engine or a dedicated race motor, this kit provides the strength and reliability you need to push your Mopar to the limit. Upgrade your engine today with high-performance parts from GGCRACING.
