Eliminate wear at the front of your Chevrolet 396-454 Block with our moly-coated roller thrust bearing. Our unique design is .142" thick and aids in setting the proper cam thrust clearance while eliminating gear to block wear.
Because all roller cam lobes are ground flat instead of tapered like a hydraulic or solid cam, it is necessary to provide some means of holding the cam back to the rear of the engine. The thrust button rides between the front of the timing gear and the back of the front cover, and can be shimmed for proper end play in the cam. Both solid nylon button and roller thrust bearing styles are availble. Wear plates eliminate the wear at the front of the block and are moly coated.
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.
