Our Billet back plates use advanced CFD simulation and exacting 3D precision milling to create a blend of engineering and manufacturing that produces less leak by, less aeration, less cavitation, and higher RPM flow.
The plate is cut from billet steel, five times as rigid as aluminum, reducing blow-by and air ingestion
Plates feature our MartenWear surfaces for extended life
Increased volume and reduced foam increase engine bearing life
Utilizes surface grinding to create the ultimate pump seal
