Rebuilding a Chevy 454? This rering kit has everything you need for a 1970-1979 Gen 4 big block engine. It includes a full gasket set from Mahle Original (formerly Victor), King rod and main bearings (available in standard, .010”, .020”, .030”, and .040” undersizes), and Mahle Perfect Circle piston rings (available in standard, .020”, .030”, .040”, and .060” oversizes). Super important: when you order, you gotta email us your bore size and bearing sizes you need—otherwise, we’ll send the kit with all standard sizes. This is a complete package for a reliable rebuild, whether you’re doing a full refresh or just replacing worn rings and gaskets. Quality parts that match OEM specs. Perfect for DIY mechanics or shops working on classic Chevy trucks and muscle cars.
