SBC Roller Lifter +.300in.

The COMP CAMS SBC Roller Lifter +.300in. (model 873-1) is a mechanical roller lifter designed for small block Chevy engines requiring increased valve lift. This Endure-X lifter delivers precision engineering for high-performance applications where elevated lift geometry is essential to optimize camshaft performance and engine breathing characteristics.

Featuring a 0.842-inch outer diameter with link bar design, this roller lifter is engineered to reduce friction and wear compared to flat-tappet alternatives. The +.300-inch dimension indicates an elevated lifter body that accommodates specific cam lobe lift requirements and valve train geometry. COMP CAMS' Endure-X construction ensures durability under sustained high-RPM operation typical in racing, street performance, and engine rebuild applications. The mechanical roller design provides consistent valve timing and reduced parasitic drag, translating to improved overall engine efficiency and reliability.

This lifter is ideal for engine builders, performance enthusiasts, and technicians assembling or upgrading small block Chevy powerplants. Whether building a street engine, competition platform, or restoration project, proper lifter selection directly impacts valve train geometry, cam profile effectiveness, and long-term durability. The SBC roller lifter +.300in. accommodates customized valve lift curves that maximize flow during critical engine operating ranges.

Roller lifters represent the modern standard in cam-follower design for performance applications, offering advantages in both reliability and repeatability over traditional flat-tappet designs.
