• Wide LS Engine Compatibility: Fits a broad range of LS engines including 4.8L, 5.3L, 5.7L, 6.0L, and 6.2L platforms such as LS1, LS2, LS3, LQ4, LM7, and LM4, making it a versatile upgrade for both car and truck applications.
• Cost-Effective Valvetrain Upgrade: Allows you to strengthen your factory rocker arms without the expense of full aftermarket rocker assemblies, delivering improved durability and performance at a fraction of the cost.
