SBC Shaft Rocker Arm Kit - 1.6/1.5 Ratio 2144-160/150

Rocker arm geometry directly impacts valve timing, lift, and overall engine efficiency—and this shaft-mount kit delivers the precision you need for consistent performance across your entire valvetrain. The 1.6/1.5 ratio provides the mechanical advantage required for aggressive cam profiles while maintaining reliability under sustained load. Aluminum construction keeps rotating mass minimal, allowing your engine to rev freely without sacrificing durability.

This kit is purpose-built for small block Chevy platforms, with direct compatibility for Dart Sportsman 2 and Pro 1 heads. Full roller design eliminates friction losses and extends component life, making it an ideal choice for bracket racing, street performance, or weekend warrior builds where dependability matters.
