GM LS7 Ultralite R/A Kit - 1.8 Ratio

The GM LS7 Ultralite R/A Kit - 1.8 Ratio by YELLA TERRA is designed for serious LS enthusiasts and race builders who prioritize lightweight and precision in rocker arm geometry. This kit is particularly beneficial for high-revving LS applications, focusing on valve train stability and minimizing parasitic losses while enhancing flow potential across the RPM range.

Engineered with a 1.8 rocker ratio, this assembly provides significant gains in valve lift response and reduces inertial load compared to OEM options. The Ultralite design incorporates precision CNC machining, ensuring a compact footprint of 8.9 x 2.3 x 17.8 inches while maintaining structural integrity under high valve spring pressures.

Ideal for engine builders and performance shops, this kit is specifically tailored for LS7 platforms, making it a valuable addition for those looking to enhance their engine's performance. Its lightweight construction, weighing just 8.45 pounds, is crucial for reducing engine friction and improving throttle response, especially in applications exceeding 6000 RPM.
