Description

The Texas Speed & Performance 1.72:1 Ratio LS3 Steel Roller Rocker Arm Set offers enhanced strength and reduced wear for your LS engine. These steel rocker arms feature a roller tip, which minimizes friction and wear on the valve tip compared to standard factory components. Engineered for a range of popular GM LS engines, this rocker arm set is compatible with LS3, L99, L76, L92, LS9, and LSA applications. This makes it an excellent option for enthusiasts seeking a robust aftermarket valvetrain solution. An important consideration during installation is that these rocker arms will necessitate a change in your pushrod length. The required length is approximately 0.175 inches shorter than the stock pushrods. It is strongly recommended to verify the precise pushrod length needed for your specific application to ensure proper valve train geometry and function.
