Why Convert to a Non-MDS Valvetrain?
The factory Multi-Displacement System (MDS) found in many 5.7L Eagle HEMI engines is a common source of camshaft and lifter failures. Converting to a Non-MDS valvetrain removes the MDS lifters while sealing the factory oil passages with MDS oil galley plugs, creating a simpler and more reliable engine configuration.
Installation Recommendations
- This kit is intended for VVT-equipped 5.7L HEMI engines being converted to a Non-MDS configuration.
- An ECM calibration or custom tuning may be required after an MDS delete conversion.
- Inspect pushrods, rocker arms, valve springs, VVT components, and timing guides during installation.
- Lubricate the camshaft and lifters with high-quality assembly lube before startup.
- Replace the engine oil and filter after installation.
- Follow factory torque specifications and service procedures.
- Professional installation is recommended.
Why Replace Everything at Once?
Replacing the camshaft, lifters, timing components, engine gaskets, and MDS oil galley plugs during one service helps reduce labor costs and minimizes the chance of future engine failures. Refreshing these wear items together improves long-term reliability and helps restore smooth engine operation.

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.
Quality Components
This kit combines premium replacement components engineered to meet or exceed OE fit and performance standards. Replacing the camshaft, lifters, head gaskets, and head bolts together helps restore smooth engine operation while reducing the likelihood of repeat repairs.
Important Fitment Information
This kit is intended for factory MDS-equipped 5.7L HEMI engines only. It should not be used for Non-MDS conversions. Always verify your VIN, engine configuration, and OEM part numbers before ordering to ensure proper compatibility. -

Complete Camshaft and Lifter Repair
This kit combines the primary components commonly replaced after a 5.7L HEMI camshaft or hydraulic roller lifter failure. Replacing the camshaft, lifters, head gaskets, and cylinder head bolts during the same repair helps support a complete top-end restoration and reduces the need to purchase each component separately.
Non-MDS Conversion Requirements
This package includes a Non-MDS camshaft and Non-MDS hydraulic roller lifters. When installing these components in an engine originally equipped with Multi-Displacement System cylinder deactivation, additional MDS oil passage plugs or other conversion components may be required. An ECM calibration may also be required to disable MDS operation and prevent diagnostic trouble codes. Confirm all conversion requirements with the installer before beginning the repair.
Installation Recommendations
- Inspect the pushrods, rocker arms, valve springs, lifter trays, timing components, and cam phaser during disassembly.
- Thoroughly clean the engine and oil passages to remove debris from the previous camshaft or lifter failure.
- Lubricate the camshaft and lifters with an appropriate engine assembly lubricant before startup.
- Install the cylinder head bolts using the factory tightening sequence and torque procedure.
- Verify camshaft timing before rotating or starting the engine.
- Replace the engine oil and filter after installation.
- Professional installation is strongly recommended.
Warranty Information
A lifetime warranty is advertised when the kit is installed by a certified machinist. Warranty eligibility, installation documentation, and claim requirements should be confirmed before installation.
Important Fitment Information
Confirm the vehicle year, engine configuration, VVT system, MDS equipment, and required conversion components before ordering. Vehicle compatibility should not be determined solely by the advertised model or year range. -

Why Convert to a Non-MDS Valvetrain?
The factory Multi-Displacement System (MDS) used on many 5.7L Eagle HEMI engines is a common source of hydraulic lifter and camshaft failures. Converting to a Non-MDS valvetrain removes the factory MDS lifters while sealing the oil passages with MDS oil galley plugs, creating a simpler and more reliable engine configuration.
Installation Recommendations
- This kit is intended for VVT-equipped 5.7L HEMI engines converted to a Non-MDS configuration.
- An ECM calibration or custom tuning may be required after an MDS delete conversion.
- Inspect pushrods, rocker arms, valve springs, timing components, and VVT hardware during installation.
- Lubricate the camshaft and lifters with high-quality engine assembly lube before startup.
- Install the included MDS oil galley plugs to properly seal the factory MDS oil passages.
- Replace engine oil and filter after installation.
- Professional installation is recommended.
Quality Components
This kit combines premium replacement components engineered to meet or exceed OE fit and performance standards. Replacing the camshaft, lifters, head gaskets, and head bolts together helps reduce future repairs while restoring smooth engine operation and dependable performance.
Important Fitment Information
Please verify your vehicle's year, make, model, engine size, and OEM part numbers before ordering. If you need assistance confirming compatibility, contact us with your VIN and our HEMI specialists will be happy to help you select the correct kit.

Why Upgrade to a Non-MDS Valvetrain?
Many 5.7L Gen III HEMI engines experience camshaft and lifter wear over time. Converting to a Non-MDS valvetrain eliminates the factory MDS lifters, providing a simpler and more reliable valvetrain configuration while restoring engine performance.
Installation Recommendations
- Inspect pushrods, rocker arms, valve springs, timing components, and oil pump for wear during installation.
- Lubricate the camshaft and hydraulic roller lifters with quality assembly lube before startup.
- Install new head bolts as included in this kit and follow factory torque specifications.
- Replace the engine oil and filter after installation.
- An ECM calibration or tuning update may be required when converting from MDS to Non-MDS.
- Professional installation is recommended.
Quality Components
This kit includes premium replacement components engineered to deliver dependable OE-style fit, durability, and long service life. It's an excellent solution for stock rebuilds, work trucks, and performance-oriented Non-MDS conversions.

Recommended Inspection Procedures
- Inspect the camshaft lobes for scoring, pitting, or abnormal wear.
- Inspect the rocker arms, rocker shafts, and related valvetrain components.
- Check all pushrods for bending, wear, or restricted oil flow.
- Inspect the cylinder heads for warpage, cracks, and valve-seat damage.
- Check the MDS solenoids and related oil-control passages.
- Clean all engine oil passages before assembly.
- Remove all metallic debris created by the original component failure.
