All 6 Speed Manual Gearbox
Porsche 986 Boxster S 2000 - 2005
Porsche 996 C2 / C4 1998 - 2005

The synchronizer ring (also called a synchro ring) helps smoothly engage gears during shifting - especially between 1st and 2nd gears - by matching the rotational speeds of the gears and shafts before the gear teeth mesh. This prevents gear grinding, reduces wear, and provides a more refined shifting feel. If a synchronizer ring becomes worn or damaged, you may experience rough shifts or difficulty selecting gears.
Function
• Speed Matching: Helps equalize speeds of the gear and shaft before engagement.
• Friction Control: Uses friction material surfaces to slow or speed parts for smooth engagement.
• Shift Quality: Promotes quieter, smoother shifting with reduced gear clash.
• Gearbox Protection: Reduces wear on gears and synchro components by facilitating correct engagement.
Synchro rings are subject to wear over time, especially under regular spirited driving or heavy use. Worn synchro rings can lead to:
• Gear grinding when shifting
• Difficult gear engagement
• Increased transmission wear Harsh or noisy shifts
Replacing a worn synchronizer ring with an OE Match part restores intended gearbox function, improves shift quality, and helps protect other internal transmission components from accelerated wear.
Replace this synchronizer ring if you experience:
• Grinding or crunching when shifting between gears
• Difficulty selecting certain gears
• Gear shifts that feel stiff or reluctant
• Noisy transmission operation during shifts
• Symptoms during gearbox rebuild or overhaul

This OE Match ring is ideal for transmission rebuilds, synchro refresh jobs, or when shifting issues are evident in the affected gears. It installs directly in place of the original ring within the transmission’s 3rd/4th synchronizer hub assembly.
The syncro ring helps match the speed of the gear to the speed of the shaft before engagement, allowing shifts into 3rd and 4th gear to occur smoothly and quietly. It bridges the difference between gears, reducing wear on dog teeth, gears, and engagement components.
Function
• Provides friction interface for speed matching between 3rd and 4th gears
• Reduces gear clash and harsh engagement
• Restores smooth shifting performance
Synchro rings wear naturally as part of normal transmission use. When they degrade, you may experience gear crunching, difficult or noisy shifts, gear hop, or faster wear on other transmission parts. Replacing them with an OE Match synchro ring restores correct shift feel, prolongs gearbox life, and helps maintain the performance and drivability expected from Porsche’s enthusiast-oriented engines.
When to replace:
• Grinding or crunching when selecting 3rd or 4th gear
• Delayed or hesitant engagement of those gears
• Transmission noise during gear changes
• During a full gearbox rebuild or synchro refresh
• Routine clutch or transmission service with high mileage
