Worn-out main bolts can cause bearing failure. This ARP stud kit is a direct fix for Mopar 426 Hemi engines.

Key Features

  • Stronger than stock — ARP 8740 chromoly steel studs are rated at 200,000 psi tensile strength.
  • Prevents main cap walk — increased clamping force keeps main caps stable under load.
  • Direct fit for Mopar 426 Hemi — designed as a replacement for factory 4-bolt main configurations.
  • Includes necessary hardware — kit comes with studs, nuts, and washers.
