Ross Tuffbond Single Stage External Oil Pump Kit - RB20 RB25 RB26 RB30

When the internal wet sump pumps just won't do the trick, an external pump is the solution of choice.  Switching to an external oil pump solution allows you to eliminate the worries of the plagued RB crankshaft collar rounding off the gears of your oil pump or having the pump detonate under high RPM stress.  The AVIAD oil pumps are built to last and take the abuse of any HP requirement thrown at the RB20DET, RB25DET, RB26DETT, and RB30 applications.  Ross Tuffbond provides the best harmonic balancers on the market with their 1,500hp rated street Metal Jacket balancer.  These are the same balancers we use on all our built motors.  This kit includes all the hardware, brackets, and gears to fit the pump to the motor.

Perfect kit to be paired up with our extended oil pan kits!
