Installation Information

This is a major internal engine repair kit. Professional installation is strongly recommended. The engine should be inspected carefully before installation to determine the cause of the original camshaft or lifter failure. Before assembling the engine, inspect the cylinder heads, rocker arms, pushrods, camshaft bearings, crankshaft, oil passages, oil control valve, MDS solenoids, and oil pan for metal contamination or additional damage.

Recommended Installation Procedures

• Clean all oil passages and internal engine surfaces thoroughly.
• Remove all metallic debris from the cylinder block, cylinder heads, oil pan, and lubrication system.
• Inspect pushrods and rocker arms for wear, bending, or restricted oil flow.
• Prime the new oil pump and engine lubrication system before initial startup.
• Use the correct assembly lubricant on the camshaft, lifters, and related components.
• Follow the proper cylinder head bolt tightening sequence and torque procedure.
• Follow all factory timing alignment and VVT installation procedures.
• Replace contaminated oil filters and perform an early oil and filter change after startup.

Fitment Notice

This kit is intended for select factory MDS-equipped 5.7L HEMI engines. It is not intended as an MDS-delete kit. Confirm the vehicle year, model, engine size, VIN, production date, and original component design before ordering. Reference numbers are provided for identification purposes only. A reference number match by itself does not guarantee compatibility with every vehicle or engine configuration.

Warranty Notice

Warranty coverage requires proper installation, correct engine clearances, adequate lubrication, and verification that the original cause of failure has been corrected. Damage caused by improper installation, contaminated oil systems, insufficient oil pressure, incorrect timing, overheating, or unresolved engine problems may not qualify for warranty coverage.

Professional Installation Recommended

This rebuild kit is intended for major internal engine service. Professional installation by a qualified engine builder or certified machinist is strongly recommended to ensure proper engine timing, lubrication, and valvetrain operation.

Recommended Inspection Procedures

• Inspect rocker arms, rocker bearings, and pushrods.
• Inspect camshaft bearings for wear or damage.
• Verify proper operation of MDS solenoids and oil-control passages.
• Clean all engine oil passages before assembly.
• Remove all metallic debris caused by camshaft or lifter failure.
• Prime the new oil pump before engine startup.
• Install the timing components using factory timing marks and procedures.
• Follow the factory torque sequence for all cylinder head bolts.
• Use assembly lubricant on camshaft journals and lifter rollers.
• Replace engine oil and filter after initial startup and break-in.

Fitment Notice

This kit is designed for select 2009-2022 5.7L HEMI engines equipped with factory Multi-Displacement System (MDS) and Variable Valve Timing (VVT). Vehicle year alone does not guarantee compatibility. Always verify VIN information, production date, engine configuration, and original component part numbers before ordering.

Warranty Information

This kit includes a Lifetime Warranty when installed by a Certified Machinist, subject to the manufacturer's warranty requirements. Warranty coverage requires proper installation, adequate lubrication, and correction of the original cause of engine failure. Damage resulting from improper installation, contaminated lubrication systems, insufficient oil pressure, incorrect engine timing, overheating, or failure to correct the original engine problem is not covered under warranty.

• Lifetime warranty (When installed by certified mechanic)
• Delivery time: 2-4 business days
• Free 30 day return

Professional Installation Recommended

This kit is intended for major internal engine and cylinder head service. Installation should be completed by a qualified machinist, engine builder, or automotive technician familiar with Chrysler 5.7L HEMI MDS and VVT engines.

Cylinder Head Service

The included valves should not be installed without first inspecting and measuring the cylinder heads. Valve guides, valve seats, springs, retainers, locks, installed height, valve stem clearance, and valve sealing should be checked by a qualified machine shop.

Valve seats may require machining or lapping to achieve the correct sealing pattern. Never assume new valves can be installed into used cylinder heads without inspection or machine work.

Recommended Inspection Procedures

• Inspect the rocker arms and rocker-arm bearings.
• Check all pushrods for wear, bending, or restricted oil flow.
• Inspect the camshaft bearings and cam journals.
• Inspect valve springs, retainers, and valve locks.
• Measure valve guide clearance before assembly.
• Check valve seats for wear, recession, cracking, or heat damage.
• Inspect the MDS solenoids and oil-control passages.
• Clean all cylinder head and engine oil passages thoroughly.
• Remove all metal debris from the original camshaft or lifter failure.
• Verify adequate engine oil pressure before returning the vehicle to service.
• Prime the lubrication system before initial startup.
• Follow all factory timing, torque, and assembly procedures.

Fitment Notice

This kit is designed for select 2009-2022 5.7L HEMI engines equipped with factory MDS and VVT. It is not intended for non-MDS engines or MDS-delete conversions.

Vehicle model and year alone do not guarantee compatibility. Confirm the VIN, production date, cylinder head design, camshaft configuration, valve dimensions, and original part numbers before ordering.

Warranty Information

The stated lifetime warranty applies when the components are installed by a certified machinist and remains subject to the manufacturer’s complete warranty terms. Documentation of professional installation and machine work may be required.

Warranty coverage may not apply to failures caused by improper installation, incorrect valve clearances, inadequate lubrication, contaminated oil passages, insufficient oil pressure, incorrect valve timing, overheating, piston-to-valve contact, or failure to correct the original cause of engine damage.

Maintains Factory MDS Performance

This kit is designed for engines that continue using Chrysler's factory Multi-Displacement System (MDS). The included MDS-compatible camshaft and hydraulic roller lifters restore proper valvetrain operation while maintaining the original cylinder deactivation system and Variable Valve Timing (VVT).

Installation Recommendations

• Verify the engine is equipped with the factory MDS and VVT systems before installation.
• Inspect pushrods, rocker arms, valve springs, timing components, and oil passages during disassembly.
• Clean the engine thoroughly after any camshaft or lifter failure to remove metal debris.
• Lubricate the camshaft and hydraulic roller lifters with quality engine assembly lube.
• Install new cylinder head bolts using the factory torque-angle procedure.
• Replace the engine oil and filter after completing the repair.
• Professional installation is strongly recommended.
