Howards Cams Direct Lube Mechanical Lifters Extreme Duty Solid Lifters Today's cams have more aggresive lobes. Increasing oil supply to these lobes is critical. A precision "E.D.M." laser burns a .021" hole in the bottom of the lifter. This allows a constant oil supply to the cam lobe, allowing higher valve spring pressures, more aggressive profiles and reduced lobe wear.
