New Solid Roller Lifters For GM Gen III (LS1, -2 & -6) engines deliver a weight savings of 14 grams per tappet over the earlier #8950 Gen III solid roller tappets allowing your Gen III engine to rev even higher - thanks to significantly reduced valve train weight. An enhanced, pressure fed oiling design, including EDM Oil Injection to the roller axle and bearing, ensures long life, even when used in a street application. New COMP Cams® Gen III Solid Roller Lifters also feature a Tool Steel axle, precision-sized needle bearing rollers and rebuildable design to ensure years of dependable service in even the most demanding of applications. They are available individually or in sets of 16 for 1997 to current LS1, LS2 and LS6 engines and can be run with COMP Cams® Gen III street and race solid roller camshafts or with any other Gen III solid roller camshaft. Single lifter only, does not include link bar; 16 required per engine.
