Rocker On Shaft - 1.650 Long .050 RH Offset

The Rocker On Shaft - 1.650 Long .050 RH Offset by T AND D MACHINE is a precision shaft-mount rocker arm engineered for high-performance engine builds where reliability and consistent valve actuation demand exacting tolerances. Designed for big block Chevy applications, this rocker arm delivers the kind of engineered performance serious engine builders and performance mechanics depend on when assembling stroker motors, LS conversions, or competition-grade powerplants. The right-hand offset geometry ensures optimal geometry alignment on specific engine configurations where standard rocker geometry would compromise valve train efficiency or clearance.

Machined from aluminum with a full roller design, this rocker arm minimizes friction across the pushrod interface while maintaining structural rigidity under sustained high-RPM operation. The 1.80 ratio geometry provides a mechanical advantage that amplifies camshaft lift, translating into increased valve opening duration and better cylinder head breathing—critical for engines targeting peak horsepower and torque output. The .050-inch right offset and 1.650-inch length specification ensure precise pushrod alignment and consistent rocker geometry, preventing binding or excessive wear on the valve stem and pushrods during extended engine duty. This attention to dimensional accuracy is what separates OEM-grade components from budget alternatives in serious buildup scenarios.

This rocker arm is ideal for engine builders and performance shops constructing big block Chevy motors destined for street performance, drag racing, or high-output marine applications where valve train stability cannot be compromised. Installation requires correct pushrod length specification and proper rocker stud torque sequence to ensure repeatable valve lash and consistent cylinder head sealing. The shaft-mount design integrates seamlessly into rocker arm assemblies utilizing T AND D MACHINE's proven engineering platform, making it a direct solution for rebuilds, upgrades, or custom engine configurations demanding OEM-equivalent precision without the OEM price tag.
