PDD Head Bolt Kit for 1998.5-Current 24v and Common Rail Cummins

Power Driven Diesel head bolts are a great economical option for mild to moderate builds.

Power Driven Diesel Head Bolts are class 12.9 fasteners with a special coating to enhance appearance and prevent corrosion.

Additionally, a custom-designed washer properly supports the bolt head and distributes the clamp load into the head for maximum reliability.

Power Driven Diesel Head Bolts do not require milling of the rocker towers.

They are approximately 25% stronger than stock head bolts, and we recommend them up to 550 horsepower on single-turbo applications.

Installation requires a M10 hex socket.
