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 : cca8958-16 Description : Endure-X Roller Lifter; 16 Pieces Title : 8958-16 MECH Roller Lifters, GM LSX / Warhawk California Proposition 65 : WARNING: Cancer and Reproductive Harm P65Warnings.ca.gov Lifter Diameter : 0.842 Lifter Series : Endure-X Lifter Type : Solid Roller Oil Hole vs. Axle : Perpendicular Pushrod Seat Location : All Centered Seat Height : 2.01 Weight : 118 2004-2005 Cadillac CTS V V8.-cc Engine Components::Lifters 2006-2007 Cadillac CTS V V8.5967cc Engine Components::Lifters 1998-2002 Chevrolet Camaro Z28 V8.-cc Engine Components::Lifters 1998-2002 Chevrolet Camaro Z28 SS V8.-cc Engine Components::Lifters 2003 Chevrolet Corvette 50th Anniversary Edition V8.-cc Engine Components::Lifters 2003 Chevrolet Corvette 50th Anniversary Edition Pace Car V8.-cc Engine Components::Lifters 1997-2005 Chevrolet Corvette Base V8.-cc Engine Components::Lifters 2006-2007 Chevrolet Corvette Base V8.5967cc Engine Components::Lifters 1998 Chevrolet Corvette Indianapolis 500 Pace Car V8.-cc Engine Components::Lifters 2001-2004 Chevrolet Corvette Z06 V8.-cc Engine Components::Lifters 2005-2006 Chevrolet SSR Base V8.-cc Engine Components::Lifters 2005-2006 Chevrolet SSR Base V8.5967cc Engine Components::Lifters 2006-2007 Chevrolet Trailblazer SS V8.5967cc Engine Components::Lifters 1998-2002 Pontiac Firebird Formula V8.-cc Engine Components::Lifters 1998-2002 Pontiac Firebird Trans Am V8.-cc Engine Components::Lifters 2004 Pontiac GTO Base V8.-cc Engine Components::Lifters 2005-2006 Pontiac GTO Base V8.5967cc Engine Components::Lifters
