Non-MDS Conversion & Hemi Valvetrain Repair: Complete Non-MDS Camshaft & Lifter Overhaul Kit for Chrysler/Dodge/Jeep 5.7L Hemi V8 (2009-2015)

Are you dealing with the dreaded "Hemi tick," severe engine misfires, or a sudden loss of power on your 2009-2015 5.7L Hemi V8? These are classic, widespread warning signs of a collapsed Multi-Displacement System (MDS) lifter. When the factory MDS lifters fail, their roller bearings seize, quickly wiping out the camshaft lobes and sending metal debris through your engine. Replace diagnosed worn valvetrain components during a non-MDS conversion with this Ultimate MDS Delete Overhaul Kit. Engineered specifically for the 5.7L Hemi platforms found in Dodge, Jeep, and Chrysler vehicles, this comprehensive package provides the exact core components needed to mechanically bypass the problematic MDS system and upgrade to a durable, standard valvetrain setup.

Sourcing a matched non-MDS camshaft, standard lifters, and the highly specific block-off plugs required for an MDS delete can be a frustrating and expensive process. This premium master overhaul kit takes the guesswork completely out of your engine rebuild. It features a robust standard non-MDS camshaft, a full set of 16 standard hydraulic roller lifters, and the crucial MDS block-off plugs needed to seal the factory oil galleys. Combined with premium Multi-Layer Steel (MLS) head gaskets and brand-new Torque-to-Yield (TTY) cylinder head bolts, this kit provides components for a top-end restoration when matched to the correct engine and installed according to applicable service procedures.
