Description

By eliminating the active fuel management oil passages found in AFM-equipped Gen 4 engines, it serves as a critical upgrade for performance camshaft installations and reliability-focused engine builds. This unit is manufactured from durable cast aluminum with a clean, natural finish. It is specifically configured as a non-PCV design, making it compatible with LS2 (6.0L), LS3 (6.2L), and LS7 (7.0L) platforms, as well as being widely used on 5.3L and 6.0L Gen 4 LS engines during conversion builds. The product includes all required mounting bolts, valley cover gaskets, and necessary seals, allowing for a complete, hassle-free installation without the need to source additional hardware.
