OE Pro 91530230106 Synchro Ring Gear Porsche Transmission - 1st 911 915

The OE Pro 91530230106 is a synchronizer ring designed specifically for first gear in the Porsche 911 915 transmission. This friction ring synchronizes the speed of the transmission to that of the drivetrain before shifting, permitting the gears to engage without grinding. This component fits 1977-1986 Porsche 911 models equipped with the 915 transmission and is sold individually.

Key Features:

• OEM-quality synchronizer ring for 915 transmission first gear
• Prevents gear grinding by synchronizing transmission and drivetrain speeds
• Direct replacement for worn synchronizer rings
• Sold individually - one per vehicle required for first gear
• 80mm diameter design

When synchros begin to wear down, the gears will engage at different speeds, resulting in gear grinding. Replacing your synchro rings at the first sign of grinding will save you from a much more costly job of replacing your dog teeth and sliders. This part supersedes Porsche part number 91530230106 and cross-references to OEM numbers 915-302-301-06, 915.302.301.06, and 91530230113.
