Why Upgrade?

Stock lifter cuffs work fine, but they limit your camshaft options and don't have the wear resistance you need for performance builds or high-lift cams. Feuling developed these lifter cuffs after discovering that billet lifter cuffs—the go-to upgrade for many builders—were actually causing problems. Billet cuffs rub on the steel lifter flats, creating debris and harmonics. Worse, they allow excessive lifter rotation and rocking, which can lead to axle and roller failure. It only takes a few degrees of rotation for the lifter roller to stop spinning, and once that happens, you're looking at serious damage. Feuling's solution? Injection-molded glass-filled nylon with a Teflon additive. This material increases wear and friction resistance while being stronger than factory replacements. The added friction reducer means smoother operation and longer life. These lifter cuffs also have increased clearances for larger lift camshafts—you can run up to Feuling's 618 lift camshaft without modification. Factory cuffs max out around 0.540" lift. Includes ARP fasteners and wedge lock washers. Recommended to be used with Feuling lifters for the tightest fit, but they're compatible with other branded lifters as long as the lifter has a light slip to snug fit in the cuff. Made in USA. Important install note: the lifter cuff may hold the lifter upward, so be sure to firmly push down on the lifter to ensure it's seated on the camshaft before installing or adjusting pushrods. Torque bolts to 96 in/lbs with red Loctite. If you're running a high-lift cam or just want better lifter performance and longevity, these lifter cuffs are the answer.
