Detailed Description

The Pioneer Cables PE-104 expansion plug kit is made for engine block sealing service on many classic GM platforms, including Chevrolet Camaro, Impala, Nova, El Camino, Blazer, and GMC Jimmy applications. It also covers numerous Chevrolet and GMC truck and van models from the 1960s through the 1980s, making it a practical choice for restoration work and engine rebuilds. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

As a steel plug option, PE-104 uses cold rolled construction for strength and a zinc-plated finish to help resist corrosion in demanding engine environments. Pioneer Cables PE-104 is a direct-fit style solution for service on compatible GM cylinder block applications where a steel expansion plug is specified.
