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.
