COMP Cams 4795 Top Dead Center Stop is a heads-on, 14 mm bolt-style TDC locating tool made from cadmium-plated steel for precise engine timing and secure crankshaft positioning.

This compact, vehicle-specific TDC stop is engineered to hold the crank at top dead center safely while you set cam timing, install gears, or perform valve work. Built in the United States with durable steel and a corrosion-resistant cadmium finish, the 4795 provides a positive mechanical stop that fits engines designed for a 14 mm bolt-style locator. The unit ships individually and is sized to be easy to store in a tool roll or toolkit.

How does this TDC stop help when aligning cam or crank timing?

The 4795 gives a fixed, repeatable stop point at top dead center so you can align timing components without relying on guesswork. It prevents the crank from rotating past TDC while you set or verify camshaft position, chain tensioners, or timing marks.

• Locks crankshaft rotation at TDC using the engine’s heads-on access point
• Maintains exact positioning during gear or chain installation
• Reduces risk of losing timing reference while you work

What engine fit and mounting style does the COMP Cams 4795 use?

This model is a bolt-style TDC stop that installs with a 14 mm fastener location on engines designed for a heads-on stop. It is vehicle-specific, so confirm compatibility with your engine’s TDC boss or threaded hole before purchase.

• 14 mm bolt-style mounting to match engines with corresponding boss
• Heads-on installation—no need to remove the oil pan for access
• Sold individually for single-engine use or replacement

What materials and durability features should I expect?

The 4795 is manufactured from steel and finished with cadmium plating for corrosion resistance and long-term durability in a workshop environment. The solid construction withstands repeated use when setting or checking timing components.

• Steel core for strength under mechanical stop loads
• Cadmium-plated finish resists rust and chemical exposure
• Compact, low-mass design for easy handling and storage

How compact is the tool and what are the logistics of use?
