Boundary High-Flow Anti-Cavitation Backing Plate

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 more high RPM flow.

-Plate is cut from billet steel, 5 times as rigid as aluminum, reducing blow by and air ingestion
-Plates feature our MartenWear surfaces for long life
-Increased volume and reduced foam increases engine bearing life
-Utilizes surface grinding to create the ultimate pump seal
-Includes high pressure o-ring seal to eliminate leaks
