Designed to overcome the AFM that disables four of the eight cylinders for better fuel economy in Chevy Corvette, Camaro and CTS-V V-8 engines, the Harding Performance AFM delete valley cover allows you to delete Active Fuel Management without having to tap or pound plugs into the block.
The 6061-T6 billet aluminum cover blocks the oil feed holes in the valley of the block that would normally supply the AFM solenoids. This offers a bolt-on solution for AFM delete when combined with non-AFM lifters such as LS7 or GM Racing lifters.
Two versions are available. The first is for LT1, L83, and L86 Corvette V-8s. Please see this link. store.hardingperformance.com/lt1-l83-l86-afm-delete-valley-cover-p35.aspx
The second version is specific to the LT4. Please see store.hardingperformance.com/lt4-afm-delete-valley-cover-p5.aspx
Both kits come with titanium bolts.
