Working alongside the synchroniser ring, dog teeth, synchroniser hub and selector sleeve, the synchro brake band creates the friction required to slow or accelerate rotating gearbox components, allowing second gear to engage smoothly and efficiently. Precision engineering ensures reliable gear synchronisation, improved shift quality and reduced wear on internal transmission components.
What This Product Does:
- Assists in synchronising gear speeds before second gear engagement.
- Works as part of the transmission synchroniser assembly.
- Helps provide smooth and accurate gear changes.
- Reduces gear clash and grinding during shifting.
- Supports proper operation of the synchroniser ring and hub.
- Minimises wear on transmission engagement components.
- Contributes to reliable manual gearbox performance.
Symptoms Of Wear Or Failure:
- Difficulty engaging second gear.
- Gear grinding or crunching when shifting into second.
- Increased resistance during gear changes.
- Notchy or inconsistent shift quality.
- Requirement to shift slowly to avoid gear clash.
- Excessive gearbox noise during gear engagement.
- Poor synchronisation between gear and shaft speeds.
- Accelerated wear of synchro rings, dog teeth and selector sleeves.
Why Replacement Matters:
- The synchro brake band is subjected to constant friction and wear every time second gear is selected. Over time, the friction surfaces can wear down, reducing the component's ability to equalise rotational speeds before gear engagement. This can result in difficult shifting, gear clash and increased stress on other synchroniser components.
- A worn brake band can compromise synchroniser performance and accelerate wear throughout the gearbox. If left unresolved, continued operation may lead to damage of synchro rings, dog teeth and selector sleeves, potentially resulting in more extensive and costly transmission repairs.
- Replacing a worn synchro brake band restores proper synchronisation, improves shift quality and helps protect the gearbox from premature internal wear. An OE Match replacement provides factory-style fitment, precision manufacturing and long-term durability, ensuring smooth and dependable transmission operation for your Porsche.

Information
Ring for syncro gear.
OE Match-quality synchronizer ring (synchro ring) - designed for use inside the manual transmission gearbox of various Porsche 6-speed models. It is engineered to meet the original Porsche specification, providing a direct-fit, high-precision replacement part for smooth gear engagement.
Sold each.
Fits:
All 6 Speed Manual Gearbox
Porsche 986 Boxster S 2000 - 2005
Porsche 996 C2 / C4 1998 - 2005
Diagram Ref No. 3
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

Information
Syncro ring, manual transmission
Synchroniser ring is a replacement designed for Porsche manual gearbox applications, ensuring smooth and reliable gear changes. Installed within the transmission’s synchromesh hub assembly, this ring facilitates the engagement of gears by matching rotational speeds before meshing, thereby eliminating grinding and excessive wear. Built to match Porsche’s original specification.

Porsche 911 (993) (1995-1998) (3rd-6th gear and reverse gear)
Porsche 911 (996) GT2 (2002-2005) (3rd-6th gear)
Porsche 911 (996) GT3 (2000-2005) (3rd-4th gear)

• Position: Inside manual transmission, synchromesh ring for one of the gear sets (often 3rd/4th gear or 5th/6th depending on the gearbox).
• Function: Enables gear engagement by synchronising shaft speeds, preventing gear-grinding, facilitating smooth shifts and protecting gear teeth and synchroniser hubs.
• Applications: Ideal when the transmission is open for rebuild, when synchroniser wear is apparent (hard or noisy shifts, grinding) or when restoring a Porsche manual gearbox to high performance.
The synchroniser ring is key to proper manual gearbox operation. Over time, wear, heat and load cause the sliding surfaces to glaze or the ring teeth to degrade, leading to symptoms such as gear clash, difficult shifts, poor gear engagement or even damage to gear teeth and hubs. Replacing the synchroniser ring ensures:
• Smooth, reliable gear engagement
• Reduced gear-grinding and longer synchroniser life
• Protection for the gearbox internals from further wear
• Enhanced driving experience and drivetrain reliability
When to replace:
• The gearbox exhibits grinding when changing into a specific gear or range (often 3rd/4th or 5th/6th)
• Hard gear changes, slipping, or noise from the transmission under load
• Internal inspection shows wear or scoring on the old synchroniser ring surfaces
• You’re rebuilding the gearbox or performing a major service where opening the transmission is already necessary.
