INFO
Product Description
Overview
Is your 5.7L HEMI experiencing a persistent valvetrain tick, recurring misfire, rough idle, reduced power, or MDS operation problems? These symptoms may be related to camshaft or lifter wear, but exhaust leaks, rocker-arm damage, oil-pressure problems, timing faults, or ignition issues can produce similar symptoms. Proper diagnosis is recommended before replacement.
This aftermarket repair kit is designed for select 2009–2018 Chrysler, Dodge, and Jeep vehicles equipped with a 5.7L V8 HEMI engine, MDS cylinder deactivation, and VVT. It combines the camshaft and hydraulic roller lifter components with cylinder-head sealing parts for repairs requiring cylinder-head removal. The camshaft controls valve movement, while the lifters transfer cam-lobe motion through the valvetrain and support the existing MDS operating configuration.
Common Symptoms
- Persistent ticking or tapping from the valvetrain
- Recurring cylinder misfire or rough idle
- Reduced power or uneven acceleration
- Excessive cam-lobe or lifter-roller wear
- MDS cylinder-deactivation operation problems
- Metal debris found during valvetrain inspection
Key Features
- Designed for select 2009–2018 5.7L V8 HEMI applications equipped with MDS and VVT.
- Includes a replacement camshaft for repairs involving confirmed cam-lobe wear or damage.
- Includes 16 hydraulic roller lifters arranged in four MDS-compatible front and rear guide assemblies.
- Retains the existing MDS cylinder-deactivation configuration; this is not an MDS-delete conversion kit.
- Includes cylinder-head gasket components for resealing the engine after cylinder-head removal.
- Includes valve-cover gaskets and cylinder-head bolts for related disassembly and reassembly service.
- Combines major valvetrain and cylinder-head service components in one coordinated repair package.
