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.

Installation Information

This kit is intended for major internal engine service. Professional installation by a qualified engine builder, machinist, or automotive technician is strongly recommended.

Before installing new components, the engine should be inspected to determine the cause of the original camshaft or lifter failure. Installing new parts without correcting an oil-pressure, lubrication, contamination, or valvetrain problem may result in repeated failure.

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 journals.
• Check the MDS solenoids and engine oil-control system.
• Clean the cylinder heads, oil passages, oil pan, and internal engine surfaces.
• Remove all metal debris created by the original camshaft or lifter failure.
• Verify engine oil pressure before and after installation.
• Prime the lubrication system before initial startup.
• Follow the factory timing, torque, and cylinder head bolt procedures.
• Use new engine oil and a new oil filter after assembly.

Fitment Notice

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

The supplied product information references multiple model-year ranges, including 2009-2015, 2009+, and later applications. Do not rely on the general year range alone. Compare the original camshaft, lifters, gasket design, VIN information, and reference part numbers before purchasing.

Warranty Information

The stated lifetime warranty applies when the kit is installed by a certified machinist and remains subject to the manufacturer’s complete warranty requirements. Proof of professional installation may be required.

Warranty coverage generally does not apply to failures caused by improper installation, inadequate lubrication, contaminated oil passages, incorrect valve timing, overheating, insufficient oil pressure, or failure to correct the original cause of damage.

Professional Installation Recommended

This kit is intended for major valvetrain service on 5.7L HEMI engines equipped with factory MDS and VVT systems. Professional installation is recommended to ensure proper timing, lubrication, and engine operation.

Recommended During Installation

• Inspect pushrods for wear or bending.
• Inspect rocker arms and rocker bearings.
• Verify adequate oil pressure before initial startup.
• Clean all oil passages thoroughly to remove metal contamination from failed lifters or camshafts.
• Prime the lubrication system before first engine start.
• Replace engine oil and filter after initial break-in.
• Follow the factory torque sequence and specifications for all cylinder head fasteners.

Fitment Notice

This kit is designed for select 2009+ Eagle 5.7L HEMI engines equipped with both Multi-Displacement System (MDS) and Variable Valve Timing (VVT). Verify your VIN, production year, and OE part numbers before purchasing, as engine configurations may vary by model and production date.

Warranty Information

This product includes a Lifetime Warranty when installed by a Certified Machinist. Warranty coverage applies to manufacturing defects and requires proper installation, adequate lubrication, correct engine clearances, and correction of the original cause of failure. Damage resulting from improper installation, oil starvation, contamination, overheating, or unresolved engine issues is not covered.
