Ford F-550 Super Duty Head Stud Kit - ARP - CA625+ - `03-`07. This ARP CA625+ head stud kit is designed for Ford Super Duty trucks with the 6.0L Power Stroke engine and provides a durable replacement for OE head bolts.

Built to meet the demands of higher boost, heavier towing, and performance builds, the ARP CA625+ studs offer reliable clamping consistency and fatigue resistance compared with stock fasteners. The kit is engineered for correct fitment on 2003–2007 Ford 6.0L applications and is supplied as a complete set to service all cylinders, simplifying head removal and installation while helping maintain proper cylinder head sealing under load.

Features

• Made from ARP CA625+ high-strength alloy for improved fatigue resistance
• Correct length and thread engagement for 2003–2007 Ford 6.0L Power Stroke engines
• Complete kit includes studs, nuts and washers for all cylinders
• Designed to provide consistent clamp load for head gasket integrity during high-load conditions

This kit is aimed at enthusiasts and technicians upgrading or restoring a 6.0L Power Stroke in F-550 Super Duty trucks. Proper installation helps ensure even clamping and simplifies maintenance compared with repeated reuse of original torque-to-yield bolts.
