• FEULING Lifter cuffs are injection molded Glass-Filled Nylon with Teflon® adder to increase wear and friction resistance. Stronger than factory replacements with added friction reducer.
• Developed due to billet lifter cuffs being found to cause debris and harmonics due to rubbing on the steel lifter flats. Billet cuffs allow excessive lifter rotation/rocking which can lead to axle/roller failure as the lifter is naturally trying to roll off the camshaft lobe. Only takes a few degress of rotation for the lifter roller to stop spinning.
• Increased clearances for larger lift camshafts. Able to use with up to our 618 camshaft without modification. Factory allows up to ~0.540" lift.
• Recommended to be used with FEULING lifters as they fit the tightest, however other branded lifters are compatable. Lifter should have a light slip to snug fit in cuff.
• Includes ARP fasteners and wedge lock washers. Torque bolts to 96in/lbs with Red Loctite.
• Made in USA


•Important install note: Lifter cuff may hold lifter upward. Be sure to firmly push down on lifter to ensure it is on the camshaft prior to installing/adjusting pushrods. Torque to 96in/lbs with Red Loctite.
