Product Information

Synchro Brake Band 1st Gear.
Manual transmission Synchro / Brake Band (Synchroniser band) engineered to match Porsche’s original specifications. Provides friction control during gear synchronisation, allowing smooth and quiet gear changes.

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.

92830231908

Product Information

Synchro Brake Band 1st Gear.
The 92830231908 is a genuine Porsche synchroniser brake band (often referred to as a synchro band or braking ring) used inside Porsche manual gearboxes.

Fits:
Porsche 911 1974 - 1986 (915 Gearbox)

Diagram ref no 37

•  This synchro brake band is located inside the manual transmission (gearbox) — not externally visible.
•  It forms part of the synchroniser mechanism, mounted between the hub sleeve and gear cone.
•  Its job is to provide controlled friction to help the synchro ring synchronise gear speed during shifting.

The synchro / brake band operates under constant friction every time the driver shifts gears. Over years of driving, this friction causes wear on the band’s friction surface and tension. When it wears out:
•  Gear changes become stiffer or notchy
•  Drivers may experience grinding noises when shifting into 1st or 2nd gear
•  The transmission may “crunch” or resist engaging lower gears
•  There may be slippage or hesitation before the gear fully engages.
If ignored, a worn synchro band can damage associated parts — like the synchro rings, hubs, or even gear teeth.

Replacement is recommended during:
•  Transmission rebuilds or overhauls (especially if the gearbox is open)
•  When experiencing hard or noisy shifting into 1st or 2nd gear
•  After high mileage or track use, where shifting load is higher
•  Anytime a synchro ring or gear hub is replaced — the band should be renewed at the same time.
Because it’s an internal gearbox part, it’s most efficiently replaced during gearbox servicing or clutch/transmission removal work.
