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

  • America's muscle car is a blockbuster at the strip, and our pumps are made to keep the camera rolling. These pumps are made from heat treated 4140 chromoly billets, in house, right where the world's best selling muscle car is made, THE USA. Boundary oil pumps are guaranteed for as long as you... or the next guy owns them.

  • Utilizes surface grinding to create the ultimate pump seal

  • Includes high pressure o-ring seal to eliminate leaks
