ARP 250-4202 Diesel Head Stud Kit 03-07 Ford 6.0L Powerstroke

The ARP 250-4202 diesel head stud kit replaces the factory torque-to-yield head bolts on the 6.0L Powerstroke with reusable, high-strength studs. Studs give more even clamping force and more accurate torque readings than stretch bolts, which is why they are a popular head gasket reliability upgrade on 6.0L engines, whether stock or modified.

• ARP-manufactured alloy studs with thread rolling after heat treatment
• Includes studs, 12-point nuts and hardened washers for the main head fastener locations
• Reusable, unlike the factory torque-to-yield bolts
• Complements a head gasket service or a higher-boost tune

Fitment: 2003-2007 Ford F-250/F-350/F-450/F-550 Super Duty and 2003-2005 Excursion with the 6.0L Powerstroke; also listed for 6.0L E-Series vans.

Note: The inner-row M8 head bolts are not part of this kit. ARP sells them separately as ARP 250-4206 to complete the factory torque sequence. Always confirm your exact model and build date before ordering.
