INA 99310514106 Hydraulic Valve Lifter Tappet HVA

The INA 99310514106 is a precision-engineered hydraulic valve lifter (also known as a hydraulic tappet or hydraulic valve adjuster) designed to maintain automatic, zero-clearance valve adjustment using engine oil pressure. Manufactured by INA, a Schaeffler Group brand and globally recognized leader in engine valve train components, this lifter delivers consistent performance and reduced maintenance compared to solid tappet alternatives.

Hydraulic valve lifters eliminate the need for periodic manual valve clearance adjustments by using pressurized engine oil to automatically compensate for wear and thermal expansion throughout the valve train. This results in quieter engine operation, extended component life, and optimized valve timing for improved performance and fuel efficiency.

Key Features:

• OE-quality hydraulic valve lifter engineered to original manufacturer specifications
• Automatic zero-clearance adjustment via engine oil pressure — no manual valve adjustments required
• Precision-manufactured by INA (Schaeffler Group), a trusted OEM supplier to major European and global automakers
• Reduces valvetrain noise and wear for quieter, smoother engine operation
• Manufactured from high-grade hardened steel for durability and resistance to wear
• Direct OEM replacement — matches original fit, form, and function
