Hydraulic Lifter Conversion Kit for 6.7L Cummins

If you’re building your 6.7L Cummins for more power, more RPM, or just more reliability, upgrading the valvetrain is a must—and the Wagler Hydraulic Lifter Conversion Kit gives you a solid foundation to do it right. Designed for 2019–2025 Ram trucks, this kit allows you to convert the factory hydraulic lifters into a solid setup without the need for a full lifter replacement, making it a practical upgrade for performance-minded diesel owners. Instead of swapping out the entire lifter, Wagler’s approach is smart and efficient. The kit utilizes your factory hydraulic lifter body, but replaces the internal hydraulic mechanism with a precision-machined solid spacer, effectively turning it into a solid lifter. This change improves valve control under high-rpm or high-load conditions—exactly where hydraulic lifters tend to fall short. You’ll notice improved durability and consistency, especially in performance or race applications where valvetrain stability is critical.

High-Quality Hardware for Install

The kit includes Wagler’s custom pushrods along with OE-style adjustable rockers, giving you everything needed to dial in proper lash and maintain precise valve timing. The adjustability built into the rockers makes setup easier, and it allows you to fine-tune the system based on your cam profile and overall engine build. Now, it’s worth noting that installation isn’t a basic bolt-on job. Special tooling may be required to complete the install with the engine in the truck, and depending on your setup, you may need to pull the engine for access. That said, for anyone already tearing down for a cam swap or major upgrade, this is a smart addition that brings long-term reliability to the top end of your build.
