COMP Cams 5552-KIT Premium Kit, 1 Pack

The Premium level kit contains all the components needed to remove the systems that disable four engine cylinders under light-load conditions to improve fuel economy, but also limit performance in the process. They are: 8 OE-style drop-in lifters (to replace those in DOD/AFM-affected cylinders), lifter trays, head gaskets and bolt kit, LS3 valley cover, timing cover gasket and seal, and water pump gaskets.
