When other aftermarket pump gear options did not meet our quality and tolerance standards, we partnered with Boundary Pump Gears, experts in their field, and designed a 48RE pump gear set that not only hold the tight clearances needed to maintain consistent pressures, but also flow up to 15% more volume than OE gears. The Boundary pump gear is made from double heat-treated chromoly steel and will not wear like powdered-metal process gears.
