RCD 6.7 Powerstroke Billet Injector Hold Down Fork Kit (RCD-1745340004)

Upgrade the weak link in your 6.7L Powerstroke fuel system with the RCD Performance Billet Injector Hold Down Fork Kit. Factory OEM torque-to-yield (TTY) injector hold downs are known to fail—even in stock applications—and become almost guaranteed to break under higher power levels, boosted cylinder pressures, or repeated heat cycles. When they snap, injectors can lift, causing catastrophic fuel leaks, loss of compression, or worse.

This complete kit replaces the brittle cast/stamped factory forks and single-use TTY bolts with a far stronger, reusable solution designed for reliability and performance.

Key Features

• 4140 heat-treated billet steel forks for superior strength and durability
• Full set of 8 billet hold-down forks
• 180,000 PSI high-tensile strength hold-down bolts (reusable—no more buying new OEM hardware every time you service injectors)
• Special contoured hold-down cup washers for proper load distribution
• Direct OEM replacement design

OEM Cross-Reference

• EC3Z-9C334-D (forks)
• BC3Z-00812-B (bolts/washers)

Fitment

2011–2023 (and later compatible) Ford Super Duty trucks equipped with the 6.7L Powerstroke diesel engine (F-250, F-350, F-450, F-550).

Whether you’re keeping your truck stock, chasing more power, or simply want peace of mind during injector service or CP4-related work, these billet forks and high-strength fasteners eliminate a common failure point.
