Endure-X Solid Roller Lifters from COMP Cams are engineered to withstand the demands of aggressive cam lobe designs and increased RPM ranges, and are not designed for street use. They feature a wear resistant tool steel axle, precision sorted needle bearings and EDM Oil Injection Technology that guarantees the bearing assembly receives a constant flow of oil. Endure-X Solid Roller Lifters are heat treated, machined to ultra-high tolerances and fully rebuildable. * Patented link bar assembly combines the benefits of a removable link bar with the safety of a captured link bar * EDM Oil Injection Technology guarantees that the bearing assembly receives constant, pressurized oil flow via precision hole aimed at the bearings * Needle bearings are precision sorted by size to evenly distribute loads, which prevents premature wear and failure * Durable axle is made from wear resistant tool steel to prolong the life of the roller assembly, especially in high RPM applications PartNumber : cca8993-16 Description : Endure-X Solid Roller Lifters; Style A; Includes (8) 890L-1 / (8) 890R-1 Lifters / (8) 818-L Link Bars; (8) Lefts / (8) Rights Pushrod Seat Location; Perpendicular Oil Hole vs Axle Title : 8993-16 Rollr Lifter, 875 OD Std GM BL K SB2 Head California Proposition 65 : WARNING: Cancer and Reproductive Harm P65Warnings.ca.gov Lifter Diameter : 0.875 Lifter Series : Endure-X Lifter Type : Solid Roller Oil Hole vs. Axle : Perpendicular Pushrod Seat Location : 8 Lefts, 8 Rights Seat Height : 1.88 Weight : 122 Seat Height : 1.88" Diameter : .875" Weight : 122g Engine Components::Lifters
