With full travel hydraulic lifters, higher RPM in performance engines is often limited by the incorrect positioning of the lifter's internal piston, which inevitably "pumps up" during the engine cycle. This improper location results in open valves and therefore leads to lost horsepower and sometimes even engine failure. With COMP Cams Short Travel Race Hydraulic Roller Lifters, the patent-pending design minimizes internal piston movement to cut down on open valve issues and allow higher engine RPM (thus increasing horsepower).
The surface of these lifters has been black oxided to significantly reduce surface friction, wear, and lubrication temperatures. This creates a high-performance, high-quality component.
Do I need anything special when installing these or can I plug and play. rebuilding a 1992 K2500 with a 5.7 350, already have a new cam and upgraded push rods. sorry if its a dumb question still new at this.
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
WARNING: The wires of these products contain chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Wash hands after handling.
