This precision-engineered component is a critical element within your vehicle’s valve train system. Designed to maintain zero clearance between the rocker arm (or cam follower) and the valve stem, Hydraulic Tappets 3.375mm ensure optimal engine performance, quiet operation, and reduced wear. The specified 3.375mm denotes a critical diameter or length dimension, making it essential to verify compatibility with your specific engine model before purchase.

The primary function of these hydraulic tappets, also known as hydraulic lifters, is to automatically compensate for thermal expansion and mechanical wear in the valve train. They achieve this through their internal design, which utilizes engine oil pressure to maintain constant contact. This self-adjusting capability eliminates the need for manual valve lash adjustments, a significant maintenance advantage. By ensuring valves open and close precisely as engineered, they contribute directly to consistent power output, fuel efficiency, and lower emissions.

When selecting replacement tappets, the exact specification of 3.375mm is paramount. Using components with incorrect dimensions can lead to catastrophic engine damage, including improper valve timing, excessive noise, and loss of power. Our Hydraulic Tappets 3.375mm are manufactured to OEM-equivalent standards from high-grade materials, guaranteeing precise tolerances, exceptional durability, and reliable operation under extreme temperatures and pressures.

Ideal for engine rebuilds or valve train noise remediation, these tappets restore factory-quiet operation and performance. Always install them with a fresh supply of clean, high-quality engine oil and a new filter to ensure proper initial priming and long service life. For optimal results, we recommend replacing all lifters as a complete set and inspecting associated components like camshafts and pushrods for wear during installation.
