Ford 427 Pistons Diamond FE 427 Ford Pistons Mercury 427 Pistons 427 Piston Rings

Premium Diamond forged FE Ford 427 pistons are available in many different bore sizes, compression ratios and crank stroke lengths for FE 427 Ford engines. We sell these 427 pistons to fit both stock stroke and Ford and Mercury 427 stroker engines. We have 3 different cylinder bore over sizes available. We sell flat top, dish top, dome top and custom pistons. We also have available plasma moly file fit Ford 427 piston rings.

These Diamond FE Ford 427 pistons are all high strength 4032 aluminum forged pistons which can be used with small nitrous kits. They offer great strength and durability as well as being light weight. These Mercury 427 and Ford 427 pistons provide improved engine performance and durability. They are far stronger than stock type cast or aftermarket hypereutectic pistons.

Diamond FE Ford 427 pistons provide reduced friction, better piston ring sealing, faster acceleration, more horsepower and torque and greatly improved strength. These pistons are great for any high performance or racing FE Ford 427 engine powered vehicle. They are equally at home in a restored muscle car or in a high performance street, strip or race engine. We distribute the entire line of Diamond forged 427 Ford pistons at great discount prices and we are happy to provide technical help if you need assistance.
