Yuesstloo Camshaft Holding & Timing Alignment Kit for Ford 3.5L EcoBoost Gen3 — Hardened Steel

This compact kit reproduces OEM 303-1655 functionality so technicians and experienced DIYers can hold camshafts, set timing, and remove cylinder head fasteners on Gen 3 10-speed-equipped Ford 3.5L EcoBoost engines. Built from hardened steel with a black-oxide finish, the tools resist corrosion and wear while fitting Ford GT (2017–2024), Expedition (2018–2024), F-150 (2017–2024), and Lincoln Navigator (2018–2024) models that use the upgraded 3.5L EcoBoost engine.

How does this kit ensure correct camshaft alignment during timing chain service?

The Yuesstloo kit provides dedicated holding fixtures that pin the camshafts in the factory-specified positions, preventing rotation while the timing chain is removed or installed. A separate tension tool maintains proper slack so gear and chain positions stay stable throughout the job.

• Includes two camshaft holding tools that replicate OEM locating points for precise lockup.
• Tension tool keeps chain slack controlled during disassembly and reassembly.
• Cylinder head screw removal socket accesses difficult fasteners without altering torque references.

What vehicles and transmissions is the tool compatible with?

This timing tool kit is made specifically for the Ford 3.5L EcoBoost upgraded engine family and matches the OEM part 303-1655 profile. It supports Gen 3 10-speed transmission-equipped models across Ford and Lincoln lineups within the listed model years.

• Ford GT (2017–2024), F-150 (2017–2024), and Expedition (2018–2024).
• Lincoln Navigator (2018–2024) with the 3.5L EcoBoost upgraded engine.
• Designed to match OEM alignment points and service procedures for these platforms.

What materials and finish improve longevity and usability?

The components are manufactured from high-hardness steel and finished with black oxide to resist rust and abrasion under workshop conditions. The robust construction reduces deformation risk when applying installation torque or pressing parts into place.

• Hardened steel body for wear resistance and dimensional stability.
• Black oxide coating to minimize corrosion and surface galling.
• Precision machining for repeatable fit and alignment to OEM tolerances.

What comes in the kit and how does it simplify storage and transport?

The kit ships with a compact carrying case that groups all pieces and keeps them protected between services. Organized storage reduces the chance of lost parts and speeds workflow for mobile mechanics or shop techs moving between vehicles.

• 2 x Camshaft Holding Tools, 1 x Tension Tool, 1 x Cylinder Head Screw Removal Socket.
• Pair of gloves included for cleaner handling during engine work.
• Portable case secures tools and makes inventory and transport straightforward.

Who is this for: This Yuesstloo 303-1655 alignment and holding tool set is intended for professional mechanics, performance shops, and skilled DIYers who work on Ford 3.5L EcoBoost engines and require an OEM-equivalent solution for camshaft retention and timing chain service. It’s especially useful when following Ford timing procedures on compatible F-150s, Expeditions, GTs, and Lincoln Navigators equipped with the Gen 3 10-speed setup. If you need reliable alignment, corrosion resistance, and a complete kit that mirrors the OEM tool’s role, this set is built to meet those demands.
