Worn exhaust manifold studs can leak. This ARP stud kit replaces them with stronger, more reliable fasteners.

Key Features

  • Stronger than stock bolts — ARP 8740 chromoly steel studs are heat-treated to 200,000 psi tensile strength.
  • 12-point nuts — Easier to get a wrench on compared to standard hex nuts, especially in tight spaces.
  • Improved sealing — Helps prevent exhaust leaks by providing consistent clamping force.
  • Direct fit — Designed to replace factory exhaust manifold studs on compatible Hemi engines.
