LS7 Shaft Rocker Arm Kit 1.80/1.80 Ratio

The LS7 Shaft Rocker Arm Kit 1.80/1.80 Ratio from T AND D MACHINE is an essential upgrade for serious LS engine builders focused on high-RPM reliability and consistent valve actuation. This kit is specifically designed for Chevrolet LS7 applications, ensuring optimal performance for dedicated track engines, competition-grade street machines, or heavily modified LS platforms.

Featuring a solid, full-length shaft support system instead of individual pedestal stands, this rocker arm assembly provides superior rigidity and resistance to deflection under high valve spring loads. The 1.80/1.80 ratio indicates equal rocker arm length on both intake and exhaust sides, which simplifies cam selection and tuning while delivering consistent valve lift multiplication across both cylinder heads.

Ideal for high-RPM racing, drag, road course, and forced induction applications, this rocker arm kit addresses the limitations of factory components, allowing for sustained high-RPM operation without valve train instability. Its precision-machined construction ensures minimal wear and predictable performance across numerous heat cycles, making it a reliable choice for performance enthusiasts.
