YSSNIUTOOL Camshaft Timing Alignment Kit for Ford 3.5L EcoBoost (7-Pc) with RT11 Cylinder Head Screw Socket

YSSNIUTOOL 303-1655 is a 7-piece camshaft timing and alignment kit designed to lock and align the camshafts and remove cylinder head screws on Ford 3.5L V6 EcoBoost upgraded engines.

This precision alignment set provides the fit, form, and drive needed when performing timing, camshaft removal, or head service on compatible Ford platforms. The kit mirrors OEM dimensions for the upgraded 3.5L V6 EcoBoost (not the older 3.5L 4V), and includes a specialty RT11 socket for stubborn cylinder head screw removal. Each component is machined to hold timing positions securely while you work, helping reduce reassembly errors and saving time in the shop or garage.

How does the RT11 cylinder head screw removal socket help during service?

The included RT11 socket is sized for the wider hexagonal plum head of certain cylinder head screws on Ford 3.5L engines. It uses a 1/2-inch drive for good leverage and reduces rounding or damage when extracting stubborn fasteners during head removal or repair.

• Wide-sided hex head design matches factory fastener geometry.
• 1/2-inch drive delivers improved torque control for stubborn screws.
• Also compatible with some Ford 3.7L head screw applications.

What are the kit components and how do they support accurate timing work?

The 7-piece kit includes camshaft holding and alignment pins sized to lock the camshafts and prevent rotation while you service the timing system. Using dedicated alignment tools maintains correct valve timing position and helps avoid costly engine damage from incorrect reassembly.

• Seven precision-machined tools for camshaft and crank alignment tasks.
• Designed to locate and secure camshafts in factory timing positions.
• Works with the cylinder head screw socket to complete head removal and installation safely.

How can I confirm this tool is right for my vehicle before buying?

Verify your engine is the upgraded 3.5L V6 EcoBoost (often labeled V6 or newer upgraded variant), not the older 3.5L 4V design. If your vehicle uses the 3.5L 4V engine, choose the alternate tool (part 303-1248) instead. Cross-reference your VIN, factory service manual, or consult a dealer to be certain.

• Check engine code or dealer parts lookup to confirm 3.5L V6 EcoBoost upgraded variant.
• If uncertain, compare cam cover and head bolt patterns to factory diagrams.
• Contact seller or dealer with VIN for definitive application guidance.
