Yella Terra YT 6726 Ultralite Pro Rocker Arm Kit for GM LS-Series, 1.85 Ratio

Upgrade your GM LS-series valvetrain with the Yella Terra YT 6726 Ultralite Pro rocker arm kit. Designed for LS3 applications, this shaft-mounted rocker arm system delivers a 1.85:1 ratio and a roller tip for smooth, consistent valve actuation. The lightweight aluminum construction helps reduce valvetrain mass while supporting responsive engine performance in demanding street, track, and performance applications.
The YT 6726 kit uses a rigid shaft-mount design to promote stable rocker arm operation and accurate valve movement. Its non-adjustable configuration simplifies installation while maintaining a precise factory-style setup when used with compatible GM LS-series components. The roller tip helps reduce friction at the valve contact point, supporting reliable operation and helping minimize wear across the valvetrain.
Built by Yella Terra for performance-focused engine builders, the Ultralite Pro rocker arm kit combines durable materials, efficient design, and application-specific compatibility. Confirm cylinder head, valve train, and clearance requirements before installation to ensure proper fitment. This kit is intended for GM LS-series engines requiring a 1.85 rocker arm ratio and shaft-mounted rocker arm configuration.
