The Original Billet FSR (Forged Steel Ring) Performance Pistons
Introduced late September of 2015, D&J was the first aftermarket diesel performance company to produce forged steel ring pistons. These billet pistons are specially designed to meet the growing need for a competition billet piston in the performance diesel market.
Our Forged Steel Ring Pistons are proven daily in all of our ENFORCER and PREDATOR series Cummins engines. We have pushed these pistons to 2000hp and 3300ft/lb torque FUEL ONLY on an engine dyno.
All of our Forged Steel Ring Pistons are custom machined to fit your specific application. From custom bowl designs to oddball wrist pin sizes, we can help make a piston perfect for your application.
