It’s a proven fact that OEM head bolts are the weak link in a diesel engine; especially if the engine has been modified. That’s because Chevy Duramax, Dodge/Cummins and Ford Power Stroke engines are all assembled using “Torque To Yield” (TTY) bolts and preloaded to yield and beyond (typically 100-110%). Any increases in combustion pressure can lead to problems like blown head gaskets or catastrophic engine failure. And because TTY bolts are yielded by design, they should never be re-used. ARP solves the problem by offering stronger head studs that are designed for higher clamping loads. They are available in several different strength materials to safely handle applications from performance street to all-out competition. Similar improvements over factory TTY bolts are provided by high strength ARP main studs. And there’s more. With increased performance you need the extra security that ARP flywheel and flexplate bolts can provide. Given the growth in extreme diesel competition and street add-ons, ARP is continually developing additional diesel kits.
