We offer stock replacement Sealed Power piston sets for many different Mopar Chrysler Plymouth and Dodge engines. These pistons are great for stock rebuilds, muscle car restorations, and even light duty performance applications. All of the Chrysler engines listed below used cast type pistons from the factory. The Sealed Power Piston sets we have are based on the original Chrysler designs, but with improvements due to modern manufacturing techniques ensuring a better piston, at a great price.

We have these parts available for the following V8 Mopar Dodge Plymouth Chrysler engines, 273, 318, 340, 360, 383, 400, 413 and 440. The piston sets are weight matched before packaging by Sealed Power. The pistons come with a selectively fit piston pin, and lock rings where required. We also offer the matching sealed power piston rings for all of these piston sets.

All of these Chrysler engine pistons use ring groove widths of 5/64, 5/64, 3/16. The compression height, ch, of each piston is listed in the description column.
