Schaeffler Group USA Inc.

INA’s precision engine components are developed in close collaboration with original-equipment manufacturers. Supplied to the automotive replacement market, INA rocker arms and valve tappets have a profound impact on valve timing and engine performance. They help today’s engines consume less fuel and comply with increasingly stringent emissions standards. At the same time, our products improve driving comfort and vehicle dynamics, while also extending maintenance intervals and service life.

All Schaeffler engine components are built to ISO/TS 16949 and ISO 9001 standards, and a “zero defect” internal standard.
