Description

The USA Standard Gear ZMSRA578-14 is a manual transmission cone blocker designed to replace worn or damaged synchronizer rings in the A578 transmission. This component is crucial for smooth gear engagement, specifically for the 3rd, 4th, 5th, and reverse gears. This cone blocker is engineered for compatibility with Chrysler and Dodge vehicles equipped with the A578 manual transmission. It functions as a synchro ring, facilitating the synchronization of gear speeds for seamless shifting. Application details specify fitment for the 1995-2005 Dodge Neon (Base, SE, ES, SXT) and the 1995-2001 Plymouth Neon (High Line). These applications involve the A578/NVT355 manual transmission, and the synchro ring is designed for 3rd-4th, 5th, and reverse gear engagement.
