Product Description
Harland Sharp Gen IV LS3 / L92 Adjustable Roller Rocker Arms 1.7:1 Ratio
Fits: Gen IV LS3, L99, L76, L92, L96, LS9, LSA, LY6, L77
Harland Sharp adjustable rocker arms are designed for GM Gen IV LS engines, providing precise valvetrain control and improved durability for both street and performance applications. Featuring a 1.7:1 ratio, these shaft-mount rocker arms maintain the factory LS ratio while offering the benefits of an adjustable, roller-style design.
Manufactured in the USA from high-strength aluminum, each rocker arm is CNC-machined for accuracy and equipped with a needle-bearing fulcrum to reduce friction and wear. The adjustable design allows for proper valve lash and preload setup, making them an excellent choice for camshaft upgrades or performance-oriented builds.
