JE Pistons Chevrolet Big Block 4.500in Bore 1.645in CH 1.00 CC Piston Kit

JE Pistons is known for making strong, reliable pistons that have seen a lot of action on the race track. Their Sportsman Racing Products (SRP) line is a great way to get that same performance DNA into your build without breaking the bank. This piston kit is specifically for Chevrolet Big Block engines with a 4.500-inch bore, giving you a solid foundation for a mild to moderate performance build.

These pistons are forged from 4032 aluminum alloy, which is a strong material that also handles heat well by expanding less than other alloys. This means they can take a good amount of abuse while maintaining their shape. The dedicated forging process helps optimize the strength and weight distribution across the piston. Plus, they feature forced pin oiling to make sure the wrist pin stays well-lubricated, which is crucial for longevity in a performance engine. They are made 100% in the USA, just like all JE Pistons products.

This kit includes 8 pistons, each with a dome top, designed for a 4.500-inch bore and a 1.645-inch compression distance, using a 0.990-inch pin. They are a popular choice for street/strip applications where you want improved performance over stock but don't need a full-blown race engine. Keep in mind these are not CARB approved and cannot be shipped to California.
