Melling LT AFM Cylinder Deactivation Delete Kit with Tuner for GM 5.3L

PN. MDK400-HPT

Melling cylinder deactivation delete kits convert GM engines with Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) to a conventional valvetrain, eliminating the deactivation lifters that are a well-known source of lifter failure. Each kit packages the components that have to be changed together, including a delete camshaft, non-deactivation hydraulic roller lifters and the matching lifter guides, so there is no guessing about compatible parts. Kits with a tuner include the programming interface needed to recalibrate the engine computer for the conversion.

Melling lists this kit for GM 5.3L LT engines with engine codes L82, L83 and L8B.
