Rauch & Spiegel 915-302-301-13 Synchro Ring for Porsche Transmission - 915

The Rauch & Spiegel 915-302-301-13 is a precision-engineered synchronizer ring designed for Porsche 915 manual transmissions. This component plays a critical role in ensuring smooth gear engagement by synchronizing the rotational speeds of the transmission shaft and gear before they connect, eliminating grinding and harsh shifts.

Key Features:

• OEM-quality replacement for Porsche part numbers 91530230106 and 91530230113
• Specifically designed for 1st gear on 1977-1986 Porsche 911 models with 915 transmission
• Also fits 1977 911 S models
• Precision friction surfaces ensure optimal speed synchronization
• Manufactured by Rauch & Spiegel, a leading mechanical engineering firm specializing in high-performance Porsche transmission components
• Restores smooth shifting performance to worn transmissions

Located between the synchronizer gears on the internal transmission driveshaft, synchro rings gradually wear down over time, resulting in harder shifts and eventually gear engagement issues. When replacement becomes necessary, this Rauch & Spiegel synchro ring delivers the quality and precision needed to restore your transmission's shifting performance. Cross-reference part numbers include 915 302 301 13, 915.302.301.13, 91530230113, 915-302-301-06, and 91530230106.
