Boundary Engineering Mod Motor Steel Back Plates 3v and 4V (1996-2004 4V / 2007-2014 GT500 / 2005-2010 GT)
The Ford modular motor is a classic spanning 2 decades of production, and our gears and pumps address one of its key weaknesses. Our pumps are made from heat treated 4140 chromoly billets, in house in our Texas facility, Boundary oil pumps are guaranteed for as long as you... or the next guy owns them.
Aluminum backing plates are a weak point of any oil pump because they deflect out of shape. This deflection, causes friction, wear, and aeration on the most sensitive component in your motor. Upgrade your pump with this billet steel back plate. This plate which is 5 times the stiffness of aluminum will keep your pump sealed tighter, removing bearing destroying air bubbles, while increasing overall pump pressure and volume.
