The KCM 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 (see Injection Control Pressure graphs below). 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 KCM 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. KCM even offers a LIFETIME Limited Warranty against manufacturers defects on their S.S. HPX lines!



The High Pressure Oil System operates from 500psi to over 3000psi. Components of this system must be designed to handle these pressures on a CONTINUOUS basis. In addition to pressure, the high temparatures of the engine oil and underhood environment, high pulsation rate of the high pressure oil system and the general expansion, contraction and vibration of a running Powerstroke make for a tough operating environment. The proper design of a High Pressure Crossover line is far more than just picking some hose with a high enough pressure rating and having some fittings crimped on or bending up a tube and attaching it to the engine! Make sure the HPX line you purchase is an ENGINEERED SOLUTION and not just a "slapped together" hose or tube!

The KCM S.S. HPX line IS an Engineered Solution! Chris Kersey of KCM has a degree in Manufacturing Engineering with a minor in Metalurgy. He has extensive experience designing and manufacturing MISSION CRITICAL weapons components for the military. Chris used the same tools and experience when he designed his HPX lines...see below for details:

•Designed by an ENGINEER
•Designed using SOLIDWORKS CAD/CAM Software
•"Stress Analysis" Tested using COSMOS (Now Solidworks Simulation) Software
•Tested for THOUSANDS OF MILES before ever offered for Sale
•Manufactured using High Grade MIL-SPEC S.S. Tubing and Fittings
•THOUSANDS of units in operation Without a Single Design Related Failure!

If you're comparing the KCM HPX line to those offered by our competitors at a lower price, and wondering why this line is more expensive, now you know!
