The Driven Diesel Stainless Steel High Pressure Crossover (HPX) line connects the driver side and passenger side High Pressure Oil Rails together. This results in a more balanced High Pressure Oil system with fewer pressure spikes. In most trucks, the elimination of ICP spikes and balancing of pressures in the High Pressure Oil Rails will smooth operation and may even quiet the engine somewhat.
You will NOT find a better HPX line ANYWHERE...PERIOD!!! The Driven Diesel HPX line is constructed from only the highest quality components. High Grade MIL-SPEC Stainless Steel tubing and aircraft quality steel fittings ensure thousands of miles of trouble-free operation. They even offer a LIFETIME Limited Warranty against manufacturers defects on their S.S. HPX lines!
