- Hydraulic Adjustment for Zero Lash: The lifters are filled with pressurized engine oil, allowing the internal plunger to automatically adjust and eliminate any clearance or "valve lash" in the valvetrain. This self-adjusting feature ensures optimal, precise valve timing and quieter operation by eliminating the noisy "ticking" associated with manual-adjustment lifters.
- Roller Contact for Minimal Friction: Unlike older flat-tappet designs that cause abrasive sliding friction, these lifters use a small wheel, or roller, to smoothly track the camshaft lobe. This significant reduction in friction not only extends the life of your camshaft and valvetrain components but also allows your engine to better utilize more aggressive, performance-enhancing camshaft profiles.
- Reduced Maintenance: Because the hydraulic lifters are self-adjusting, they eliminate the need for the periodic manual valve adjustments required by older mechanical lifters, saving you time and cost over the life of your engine.
- Engine Longevity: The combination of reduced friction from the roller and reduced component stress from the zero-lash hydraulic adjustment directly contributes to extending the overall life and durability of your high-performance 6.7L Power Stroke engine.

The DK Engines DK-FD6.7-LIK New Valve Lifter Set is a crucial upgrade designed for 2011–2024 Ford 6.7L Power Stroke diesel engines. These aren't just replacement parts; they are precision-engineered hydraulic roller lifters that utilize pressurized engine oil to seamlessly and quietly translate the camshaft's rotation into the precise motion needed for your pushrods and valvetrain. A valve lifter is the cylindrical component that rides the camshaft lobes, and the DK-FD6.7-LIK set leverages the most advanced design—hydraulic roller—to dramatically improve engine operation and longevity compared to older technologies. This translates directly into more precise valve timing, reduced friction, and a quieter, more durable engine.
