Valve Tappets
Premium hydraulic and mechanical valve lifters engineered for optimal valve train performance, durability, and quiet operation.
VALVE TAPPETS
Valve tappets transfer cam motion to the engine valve, ensuring precise valve timing and optimal engine performance.
High-quality valve tappets help maintain engine efficiency and reduce wear on the valve train components.
Integrated Components
Our valve tappets and rocker arms are developed as a matched system, designed to support overall valvetrain stability and long-term operation. By aligning critical dimensions, material characteristics and surface treatments, both components work together to achieve reduced friction and consistent motion under real operating conditions. This integrated solution supports a wide range of engine platforms and is suitable for OEM programs from validation through mass production, ensuring reliable performance over time.
DLC Coated Valve Tappets — Built for High Load and Low Friction
DLC coated valve tappets significantly reduce friction between the tappet and camshaft.
The ultra-hard, low-friction coating enhances surface durability and improves scuffing resistance.
DLC coated tappets are ideal for engines requiring reduced friction losses and extended service life.
Customized Valve Tappet Development
We provide tappet development support based on engine structure, cam profile, and operating conditions.
From prototype validation to stable mass production, we assist customers in selecting appropriate structures.

How Much Does Valve Lifter Replacement Cost? (2026 Guide)
Valve lifter replacement typically costs $1,000-1,800, with labor making up 70-80% of the total. Cost varies by engine type and location. Replacing all lifters at once is recommended to prevent future failures and avoid paying labor costs twice.
Lifter Tick vs Exhaust Leak: How to Tell the Difference
Lifter tick produces a rhythmic tapping synchronized with engine RPM from inside the engine, while exhaust leaks create a puffing or hissing sound that doesn't change with RPM and comes from the exhaust manifold area. Lifter tick is louder when cold and may quiet down when warm, while exhaust leaks are consistent regardless of temperature. Diagnosis involves listening location, RPM correlation, and temperature behavior.
What Does a Valve Lifter Do?
Valve lifters transfer motion from the camshaft to valves, opening and closing them thousands of times per minute. Types include hydraulic (automatic, maintenance-free), mechanical (precise, requires adjustment), and roller (reduced friction). Lifters typically last 150,000-200,000 miles with proper oil maintenance.
Can a Lifter Tick Go Away on Its Own?
Lifter tick may disappear on its own if caused by temporary oil pressure issues or air in new lifters, but persistent ticking indicates worn lifters, contaminated oil, or low oil pressure requiring attention. Simple solutions include oil changes and additives, while severe cases need lifter replacement costing $800-2,200.
