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.

Porsche 944 1982 - 1985 Manual Transmission

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

OEMatch Gearbox Syncro Ring / Brake Band / Dog Teeth — Engagement, Smoothness, Control
OEMatch gearbox synchroniser parts are practical replacements designed for Porsche models. Synchro rings, brake bands and dog teeth restore accurate gear engagement during a rebuild or repair, reduce grinding and improve shift clarity. These items are chosen for compatibility with model-specific transmission layouts and common Porsche gearbox applications.
Available Types
- Synchro rings for specific gearsets and ratios
- Brake bands sized for particular Porsche manual transmissions
- Dog rings and dog teeth for hub engagement and selector assemblies
Understanding OEMatch Gearbox Syncro Ring / Brake Band / Dog Teeth
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original gearbox synchroniser parts.
OE (Original Equipment) refers to parts matching original specifications for the gearbox synchroniser parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM gearbox synchroniser parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Synchroniser rings, brake bands and dog teeth coordinate rotational speed and positive engagement between gears; correct selection and installation support consistent shift feel and reduce the risk of incidental damage during use or rebuild. Material choice and heat treatment affect wear rates and contact behaviour, so matching part type to the transmission model is important.
Benefits Include
- Restores synchronisation to reduce gear noise and grinding
- Protects adjacent gearbox components by ensuring controlled engagement
- Helps maintain consistent shift effort across gears and driving conditions
Why Gearbox Syncro Ring / Brake Band / Dog Teeth Wear and Fail
- Friction surface wear from age, contamination or degraded lubricant
- Deformation or chipping of dog teeth due to aggressive shifting or impact
- Heat stress and inadequate lubrication during high-load operation
The Importance of Replacing with OEMatch Gearbox Syncro Ring / Brake Band / Dog Teeth
Replacing worn synchroniser components as part of a transmission rebuild or service reduces the likelihood of further gearbox damage and helps retain intended shift characteristics. Using parts matched to the Porsche transmission maintains mechanical clearances and engagement timing, supporting dependable operation and reducing the chance of secondary failure.
Advantages
- Replacements sized for common Porsche transmission types to aid fitment
- Heat-treated and machined materials for consistent contact behaviour
- Suitable for restorations, routine servicing and compatible performance upgrades
Support & Advice
Installation should be carried out by a qualified technician following model-specific procedures and torque settings. Use calibrated tools and new fasteners where specified. If you are unsure about setup, condition or backlash settings, consult a specialist with Porsche experience.
