COMP Cams 4933CPG Top Dead Center Piston Stop Deck Plate Style

The COMP Cams 4933CPG is a universal deck plate-style piston stop tool designed to accurately locate top dead center (TDC) when the cylinder heads are removed from the engine. This precision tool is essential for properly degreeing camshafts before installing the cylinder heads, ensuring optimal valve timing and engine performance.

Key Features:

• Deck plate design mounts across any cylinder bore when heads are off
• Bolts directly to the engine block using existing head bolt holes
• Universal fitment works with most V8, V6, and 4-cylinder engines
• Blue anodized aluminum construction for durability and corrosion resistance
• Positively stops piston travel to find precise TDC location
• Included in various COMP Cams degree kits (4934CPG, 4935CPG, 4936CPG)

This TDC stop is a professional-grade engine building tool ideal for engine builders, performance enthusiasts, and professional mechanics who need accurate camshaft degreeing. Unlike spark plug hole-style piston stops, this deck plate design is specifically engineered for use during engine assembly when the heads are not yet installed.
