COMP Cams® Solid/Mechanical Lifters are the highest quality solid lifters on the market today. These lifters are manufactured using the tightest tolerances in the industry to ensure peak performance in your application. The crown of the lifter is ground to a precise radius for proper break-in and optimum durability, which guarantees a long life. The oil metering band is milled to an exact depth in order to prevent too much oil from being delivered to the top of the motor, robbing precious horsepower. The lifter is the most important component between the cam profile and the valve, so make COMP Cams® Solid/Mechanical Lifters your choice for maximum power and warranty protection.
