INFO
5.7L HEMI MDS Camshaft & Lifter Kit is a factory-MDS-retaining rebuild package for the listed 2003-2008 Dodge, Chrysler, and Jeep 5.7L HEMI applications. It uses MDS hydraulic roller lifters and is a factory-system replacement rather than a Non-MDS conversion. The package combines a camshaft and MDS lifters with a timing chain kit, oil pump, MLS head gaskets, sealing components, front camshaft seal, and 30 cylinder-head bolts, allowing the confirmed valvetrain, timing, lubrication, and cylinder-head sealing parts to be ordered under one SKU. Match the vehicle year, make, model, 5.7L engine, and factory MDS configuration to the fitment information on this page before ordering.
Use this 5.7L HEMI MDS Camshaft & Lifter Kit when inspection has confirmed camshaft or lifter wear and the repair plan calls for retaining the vehicle's factory MDS system. Ticking, misfire, or rough running can have other causes, including exhaust leaks or unrelated ignition and fuel faults, so symptoms alone do not confirm that this kit is required. During teardown, compare the removed parts with the listing, inspect oil passages and related valvetrain and timing components, and follow the vehicle manufacturer's service procedures and torque sequence. This SKU is documented as an MDS-retaining repair package; it does not change the vehicle to a Non-MDS configuration.
Features
- Includes 1 camshaft, 8 front MDS hydraulic roller lifters, and 8 rear MDS hydraulic roller lifters.
- Includes 1 timing chain kit and 1 oil pump.
- Includes an MLS head gasket kit with the listed valve-cover, valve-stem, intake-manifold, and exhaust-manifold seals and gaskets.
- Includes 1 front camshaft seal, O-rings, small gaskets, and 30 cylinder-head bolts: 20 long and 10 short.
- Retains the listed vehicle's factory MDS cylinder-deactivation configuration.
- Designed for the listed 2003-2008 Dodge, Chrysler, and Jeep 5.7L HEMI applications.
