Information
Synchroniser Ring / Synchro Gear (4th - 5th gear).
This synchroniser ring is a high-quality replacement for the original Porsche synchro ring, intended for the 4th / 5th gear engagement in manual transmissions. It restores crisp shifting performance and ensures smooth gear changes under load.
Sold each.
Fits:
Porsche 924 Turbo / GT 1979 - 1984
Diagram Ref no 10.
The synchroniser ring (synchro) helps match rotational speeds between the gear and the shaft before engagement, reducing gear clash and enabling smooth shifting. For 4th ↔ 5th gear, it is especially important because these are often used under high load or highway speeds. Precise tooth profile, surface finish, and friction surface design are essential to ensure positive engagement, durability, and minimal wear.
Over time, synchroniser rings are exposed to intense friction, heat, and load during every gear change. The original rings can wear, glaze, or lose their critical friction properties, leading to:
• Hard or grinding gear shifts
• Gear pop-outs under acceleration or deceleration
• Increased wear on gear teeth and shift sleeves
• Reduced driving comfort and gearbox longevity
Replacing worn components with a replacement Synchroniser Ring ensures proper tooth engagement, restores friction characteristics, and protects the entire transmission assembly from premature wear — keeping your Porsche shifting smoothly for years to come.

Syncro Ring 2nd Gear
This Syncro Ring is a premium OE Match transmission component engineered to replicate the original Porsche synchronizer ring used on 2nd gear in the manual transmissions of early Porsche 924 (1980–1985) and Porsche 944 (1982–1985). It helps ensure smooth, accurate gear engagement by matching gear speeds before clutch engagement.
Fits:
Porsche 924 1980 - 1985 Manual Transmission: VQ VR UV MD ME MF MB MX
Porsche 944 1982 - 1985 Manual Transmission
Diagram Ref no 22
This OE Match syncro ring is ideal for transmission rebuilds, synchro refresh jobs, or whenever shift quality degrades. It installs directly into the synchronizer hub assembly for 2nd gear, restoring correct friction and gear-speed matching as designed by Porsche.
The 2nd gear syncro ring provides a friction interface that allows the gear’s speed to match the shaft’s speed before engagement, facilitating a smooth and quiet shift into 2nd gear without wear-inducing grinding or clashing.
Function
• Provides friction contact for speed matching of 2nd gear
• Reduces gear clash and abrasive engagement
• Helps restore smooth and positive shifting
Synchro rings wear with use, and as friction surfaces degrade, shifting into the affected gear becomes more difficult, noisy, or harsh. This can accelerate wear on gear teeth and other transmission components. Replacing the worn synchronizer with an OE Match synchronizer ring restores friction characteristics, improves shift quality, and extends the life of the gearbox.
When to replace:
• Grinding or crunching when shifting into 2nd gear
• Delayed or hesitant engagement
• Transmission noise during gear changes
• During manual gearbox rebuilds or overhauls
• After high-mileage or performance use
