Elgin RK-840RS SBC Roller Tip Rocker Arms 1.5 Ratio 3/8in Stud

The Elgin RK-840RS roller tip rocker arms are engineered for small block Chevrolet (SBC) engines, delivering enhanced valvetrain performance and durability. These rocker arms feature a 1.5:1 ratio and are designed for 3/8-inch rocker studs, making them a direct replacement for stock applications or performance upgrades.

Key Features:

• Roller tip design reduces friction and wear on valve stems for extended component life
• 1.5:1 rocker ratio maintains stock valve lift characteristics
• Precision-engineered for 3/8-inch rocker arm studs
• Constructed from high-quality materials for strength and reliability
• Suitable for street performance and stock replacement applications
• Compatible with small block Chevrolet V8 engines (262, 265, 267, 283, 302, 305, 307, 327, 350, 400)

These roller tip rocker arms reduce valvetrain friction compared to standard stamped steel rockers, improving efficiency and allowing smoother engine operation. The roller tip design minimizes side loading on valve stems and guides, contributing to longer valve stem and guide life. Ideal for enthusiasts looking to upgrade from factory rocker arms without changing valve lift specifications.
