Endure-X Solid Roller Lifters

The Comp Cams Endure-X Solid Roller Lifters are engineered to meet the demanding requirements of aggressive cam lobe designs and increased RPM ranges, making them a prime choice for Pontiac V8 350-455 engines, particularly in performance street applications. These lifters are constructed with a wear-resistant tool steel axle and utilize precision-sorted needle bearings. A key feature is the EDM Oil Injection Technology, which ensures a continuous and directed flow of oil to the bearing assembly, enhancing longevity and performance. They are manufactured from steel, heat-treated, and machined to ultra-high tolerances for durability and are fully rebuildable. Key specifications include a .842-inch diameter, a 2.01-inch seat height, and a weight of 120 grams per lifter. The valve lift is rated at .663"/.655" with a hot lash requirement of .024"/.026".
