The ARP Case Bolt Kit are forged from very durable materials and make for a perfect option when rebuilding an engine to hold big power. 

DETAILS:

  • All bolts undergo a generous under-head radius and heat treating for reliability
  • Threads are rolled after heat treating to make them 1000% stronger than most other main bolts
  • Bolts are rated at 200,000 psi
  • Application specific
  • Includes parallel-ground, hardened washers
  • Some engine builders recommend line honing the case to remove any distortion created by the hardware
  • Use OEM SUBARU torque specs and procedures, any other torque specs and lubricants may lead to case distortion damage.
