Fits:
Porsche 911 1974 - 1986 (915 Gearbox)
Diagram ref no 37
The synchro / brake band is part of the gearbox synchroniser system, helping to slow or control rotation of a gear or hub during shift transitions, promoting smooth engagement and preventing clash. It works in concert with the synchroniser rings, hubs, sleeves, and gearsets to align speeds of rotating parts before lock-in. Proper material, friction surface, and design are critical — the band must provide the correct friction characteristics without binding or excessive wear.
• Installation: Direct OE replacement — recommended during gearbox overhaul
• Position / Location: This part is located inside the manual transmission, within the synchroniser assembly — the mechanism that equalizes gear and shaft speeds for smooth engagement. It wraps around the synchroniser hub and works with the synchro ring and dog teeth gear to provide friction and control during shifting.
• Benefits: Restores synchroniser performance, eliminates grinding, reduces wear on gears and rings
Why replacement matters:
• With use, the original band’s friction surfaces can glaze, wear, or lose consistency, impairing its ability to slow or stabilise gear/hub motion during shifting.
• A worn or ineffective brake / synchro band can result in grinding gears, missed shifts, or gear clash, especially under load or during aggressive shifting.
• Installing a high-quality replacement restores proper friction behaviour, enabling smooth engagement, reducing wear on adjacent synchroniser elements, and extending transmission life.
• Because the transmission internals are sensitive to mismatches or degraded components, having a reliable replacement band ensures system integrity and maintains the “feel” of the gearbox.

A dog-teeth gear (or synchronizer-gear hub / 1st-2nd gear dog gear) used inside the 915 gearbox. This gear section engages with corresponding hub or clutch-dog components to allow shifting between gears - in particular 1st and/or 2nd gear depending on the configuration.
Gears inside classic 915 transmissions - especially dog / synchronizer-gears - are subject to wear over time: tooth heads can round off, suffer chip-out, or distort under load; synchronizer engagement surfaces may wear and lose precision. This can cause:
• Gear-slip or missed shifts
• Grinding or clash during shifting
• Torque transmission loss or vibration under load
• Accelerated wear of other transmission internals.
Replacing worn gears with a precisely machined, correctly hardened OE-match replacement restores gear-mesh integrity, retains gearbox performance, and helps avoid costly gearbox failure.
When to Replace.
Consider fitting this gear if:
• You hear grinding, clash, or crunching during shifting - especially into 1st or 2nd gear
• Gearbox inspection reveals worn, rounded, chipped, or damaged dog-teeth or synchronizer surfaces
• You are performing a full gearbox rebuild or overhaul
• The gearbox has high mileage or signs of internal wear
• You want to restore factory-spec shifting performance and reliability
