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.
Sold each.

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