The LS Shaft Rocker Arm Kit Frankenstein F710 Series by T AND D MACHINE represents a serious upgrade path for LS-platform engine builders pushing beyond stock limitations. This precision rocker arm assembly is engineered for enthusiasts and professional mechanics who demand reliability under high-RPM, high-lift cam profiles where factory rocker geometry falls short. Whether you're building a street performance LS or a dedicated race engine, this kit addresses the critical valve train challenge of maintaining consistent lobe contact and preventing rocker arm deflection at elevated engine speeds.
The F710 Series design utilizes a shaft-mounted configuration that distributes loads more evenly across the rocker assembly compared to traditional pedestal designs, reducing harmonics and improving valvetrain stability. The 180/180 specification denotes equal lift ratios optimized for symmetrical cam profiles, ensuring predictable valve opening and closing events across the entire RPM band. T AND D MACHINE's manufacturing standards guarantee tight tolerances and superior surface finishes on all contact points, minimizing wear and extending component lifespan under sustained high-RPM operation. The complete kit weighs 18.9 lbs and fits within compact engine bay dimensions, making it compatible with most LS-swap applications without requiring extensive frame or accessory modifications.
Experienced LS builders and shops choose this rocker arm kit when upgrading cam profiles beyond 0.550-inch lift or increasing valve spring pressures. Proper installation requires careful alignment with existing LS block saddle surfaces and coordination with compatible valvetrain components including pushrods, valve springs, and retainers. Before ordering, verify your specific LS engine generation and confirm compatibility with your planned cam profile and lift specifications to ensure optimal performance and longevity of the entire valvetrain assembly.
