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.
