One of the most common failures with the DS4 pump on the 1994-2000 Chevy 6.5L engines is the Pump Mounted Driver (PMD), located on the side of the pump. The PMD Relocation Kit moves the PMD away from this area of potential heat build up and mounts it on an extruded aluminum base to provide better heat sinking. Easy installation, plus improved access for future diagnostics and/or repair.
