SDPC MDS Delete Kit for 6.4L Gen III Hemi 2009+

Description

Eliminate failure-prone Multi-Displacement System (MDS) lifters and unlock maximum valvetrain reliability with our complete MDS Delete Kit for 2009+ Gen III 6.4L HEMI engines. Engineered as an all-inclusive hardware solution, this package includes genuine OEM Mopar "Hellcat" non-MDS lifters, reinforced lifter guides, MDS solenoid block-off plugs, and a full compliment of premium gaskets and torque-to-yield fasteners required for a trouble-free overhaul. Whether restoring stock reliability with a factory OEM non-MDS camshaft or stepping up to one of our dyno-proven performance grinds, this kit delivers the valvetrain stability your 392 HEMI demands.

IMPORTANT TUNING NOTE: Mechanically removing MDS components requires disabling the MDS system in the vehicle’s PCM to prevent diagnostic trouble codes (DTCs) and limp-mode conditions. We offer an optional pre-configured DiabloSport PredatorX tuner for quick MDS deactivation on compatible platforms. Please note: DiabloSport tuning does not currently support 2019+ Ram 2500/3500 6.4L trucks.

Gen III 6.4L HEMI MDS Delete Kit (2009+)

Platform: Chrysler / Dodge / Jeep / Ram 6.4L (392 c.i.d.) Gen III HEMI

Dyno-Proven Camshaft Options Breakdown:

Because the factory 6.4L camshaft profile matches the output of entry-level aftermarket grinds, we recommend stepping up to at least a Stage 2 profile when upgrading for power:

• Stage 2 Camshaft: Delivers a classic muscle car chop with robust midrange and an additional 25 HP at 6,500 RPM. Requires a 2,400+ RPM stall converter on 5-speed NAG1 transmissions (factory stall acceptable on 8-speed Torqueflite 8HP). Excellent for centrifugal boost applications (ProCharger / Vortech).
• Stage 3 Camshaft: Ideal for naturally aspirated builds looking to easily exceed 500 flywheel horsepower. Recommended 2,400+ RPM stall for street (2,800+ RPM on slicks) for 5-speed automatics; standard stall compatible with 8-speed transmissions.
• Stage 4 Camshaft: Maximum naturally aspirated output designed to generate 550–600+ HP with bolt-ons. Optimized for high-flow intake manifolds and free-flowing exhaust setups. Requires 2,400–2,800+ RPM stall on 5-speed platforms.
• "Grizzly Tow Power" (6.4L Truck Specific): Specifically tailored for heavy-duty Ram 2500/3500 workhorses. Broadens the low-end pulling curve with an instant +27 lb-ft bump at 2,900 RPM for maximum sustained towing capacity.
• "The Reaper" (Blower Cam): Engineered specifically for Hellcat and aftermarket positive displacement superchargers (Whipple, TVS, Kenne Bell). Gained +48 HP and +23 lb-ft on our chassis dyno untuned, carrying clean power to 7,000 RPM.
• Note on "El Choppo": While popular on 5.7L builds for its radical idle, it is not recommended for 6.4L displacement applications.

Key Kit Features:

• Genuine OEM Valvetrain Components: Includes authentic non-MDS Hellcat lifters and reinforced trays to permanently eliminate lifter collapse and needle bearing failure.
• Positive Oil Gallery Sealing: Precision Mopar gallery plugs replace the variable solenoids to maintain uninterrupted oil pressure across the lifter galleys.
• Complete Installation Package: Pre-packaged with new timing, water pump, valve cover, intake, and exhaust gaskets alongside replacement torque-to-yield head, cam phaser, and balancer bolts.
