DHD's High Pressure Pinned Duramax Oil Pump is an excellent addition to any engine build. DHD shims each pump in-house to produce approx 15-30% more oil pressure safely and dependably. Each pump is pinned to prevent slippage under high RPM and stress.
All of our wet sump high performance engine builds receive one of these upgraded oil pumps before leaving DHD.
