Part #: 292326-16

The Melling Hi-Perf Hydraulic Roller Lifters are precision-engineered components designed to enhance valve train performance for a wide range of Chrysler, Dodge, Jeep, and Ram vehicles equipped with 5.7L Hemi, 6.1L SRT8, 6.2L Hellcat, 6.4L 392, and Trackhawk engines from 2002 through 2026. These lifters deliver smooth, quiet operation while supporting high RPM capabilities, making them an excellent choice for both performance enthusiasts and professional engine builders.

Manufactured in the USA with a focus on durability and reliability, Melling’s hydraulic roller lifters provide superior wear resistance and precise oiling to ensure consistent valve train function under demanding conditions. Whether upgrading a daily driver or building a high-performance engine, these lifters offer dependable operation and extended service life.

Key Features

Designed with advanced engineering and premium materials, these lifters optimize valve train efficiency and longevity. Key features include:

• Cold forged steel body heat treated for exceptional wear resistance and durability
• Precision ground needle roller bearing with a high chromium steel axle to minimize friction and extend service life
• Cold forged extra-long piston, precision ground and fitted for controlled leak down and pump-up performance
• High flow disc-style quick reacting check valve for improved response at higher engine speeds
• Precision oil metering system ensuring proper lubrication to rocker arms without sacrificing oil pressure
• Proprietary tie-bar system for enhanced stability and alignment during high RPM operation
• Available with short travel, variable duration lift, and axle oiling features for tailored performance
• Improved OEM design specifically for non-MDS Gen 3 HEMI blocks
• Requires longer than original equipment push rods for proper fitment and function

Construction & Design

The Melling hydraulic roller lifters feature a cold forged steel body that provides outstanding strength and resistance to wear under high stress. The piston is crafted from chromium steel, delivering excellent hardness and corrosion resistance for long-lasting durability. A precision ground needle roller bearing supported by a high chromium steel axle reduces friction and enhances the lifter’s service life.

Attention to detail is evident in the high flow check valve and precision oil metering system, which work together to maintain optimal lubrication and rapid lifter response. The proprietary tie-bar system maintains lifter alignment and stability, critical for reliable valve train operation at elevated engine speeds.

Installation & Fitment

These lifters are compatible with a broad range of Chrysler, Dodge, Jeep, and Ram vehicles from 2002 to 2026, including popular models such as the Chrysler 300, Dodge Ram 1500/2500/3500, Durango, Charger, Challenger, Jeep Grand Cherokee, Wrangler, Wagoneer, and Ram trucks. They fit engines including the 5.7L Hemi, 6.1L SRT8, 6.2L Hellcat, 6.4L 392, and Trackhawk variants.

Installation requires the use of push rods longer than the original equipment to ensure correct valve train geometry and lifter function. Professional installation is recommended to guarantee proper fitment and adjustment, especially when upgrading from stock lifters or modifying engine components.
