Pro Circuit PC-04 Assembly Lube is a 5-ounce engine assembly lubricant designed to protect critical components during initial startup. Its formula helps prevent metal-to-metal contact before the engine’s normal lubrication system can deliver adequate oil, supporting smoother break-in and reducing wear on freshly assembled parts.
Use Pro Circuit PC-04 on engine components that require temporary startup protection, including bearing surfaces, camshaft components, valvetrain parts, and other metal-to-metal contact areas specified during assembly. The lubricant is also suitable for applying to bolt threads when accurate torque readings are important, helping provide consistent thread engagement during engine assembly.
Fitment: Intended for engine rebuilding, performance engine assembly, powersports applications, and other mechanical assemblies requiring reliable pre-lubrication. Verify application requirements and manufacturer service procedures before use. This product is supplied by Pro Circuit and is identified by manufacturer and vendor part number PC-04.
