It ships in a compact carry case so every piece stays organized in the shop or on the jobsite.

How does this kit ensure correct timing when working on a 5.0 Coyote V8?

The camshaft holding tools and crank locking wrench align engine components precisely to top dead center, preventing cam phasing or crank misalignment while the timing chain or guides are serviced. Using purpose-built locating pins and a slot-lock on the crank tool provides repeatable positioning without improvised methods.

• Camshaft holding plate secures both intake and exhaust camshafts in place.
• Crankshaft positioner locks the crank when the handle slot engages the dowel pin.
• Designed for Gen 1 & Gen 2 5.0 Coyote engines (2010–2017).
• Eliminates guesswork and reduces risk of valve-to-piston contact during timing work.
