OEM Head Bolts Are A Diesel Engine's Weak Link

Diesel engines are all assembled using “Torque To Yield” bolts. If the engine has been modified, any increases in combustion pressure can lead to problems like blown head gaskets or catastrophic engine failure. ARP's Diesel Head Stud Kits are designed for higher clamping loads and much safer and stronger than OEM. They are available in several different strength materials to safely handle applications from performance street to all-out competition.
