The GM LS7 Ultralite R/A Kit - 1.8 Ratio is a high-performance valvetrain upgrade designed specifically for the General Motors LS7 engine platform. This kit provides automotive enthusiasts and professional engine builders with a reliable solution for increasing valve lift and enhancing valvetrain stability during high-RPM operation. By replacing factory components with this shaft-mounted system, users can achieve more precise valve control and improved durability in demanding street or track environments.
Engineered with a 1.80 ratio, the GM LS7 Ultralite R/A Kit - 1.8 Ratio utilizes premium aluminum construction to significantly reduce reciprocating weight without compromising structural integrity. The Ultralite design minimizes inertia at the valve, while the roller tip reduces friction and side-loading on the valve stems to prevent premature guide wear. Its shaft-mount configuration ensures rigid alignment across the cylinder head, providing a much more stable platform than traditional stud-mounted rockers for consistent performance.
This GM LS7 Ultralite R/A Kit - 1.8 Ratio is an essential upgrade for those looking to maximize the efficiency of their LS-series valvetrain while maintaining a factory-style fitment. The comprehensive kit includes the necessary components for a complete installation, making it a preferred choice for those researching specifications for high-performance LS7 builds. Whether you are conducting a full engine overhaul or looking to buy a review-proven upgrade for your valvetrain, this Yella Terra system offers the precision and strength required for modern LS performance applications.
