Redline USA MDS 5.7 HEMI Lifters Camshaft Kit w/Head Gasket Set Replacement for Dodge Ram 1500 5.7L V8 2009-2015 Part# HS26423PT, 53022263AF, 53021726AD, 53021726AE

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.
