This Sunroof Clutch is an OE-style drive coupling component designed for the electric sunroof mechanism on Porsche 911, 964, and 993 models. It connects the sunroof motor to the transmission drive assembly, allowing smooth and controlled operation of the sliding roof system. Installed between the electric sunroof motor and the sunroof gearbox/transmission mechanism, the clutch acts as a flexible coupling that absorbs vibration and compensates for minor driveline movement within the roof mechanism. This helps ensure quiet, smooth, and controlled opening and closing of the sunroof panel.
Fits:
Porsche 911 1974 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998
Diagram ref no 29
The sunroof clutch transfers drive from the electric sunroof motor to the roof transmission mechanism while absorbing vibration and driveline shock. It enables smooth and reliable opening and closing of the electric sunroof system.
Function
• Connects sunroof motor to transmission assembly
• Transfers rotational drive to the sunroof mechanism
• Absorbs vibration and driveline movement
• Helps ensure smooth and quiet sunroof operation
• Protects motor and gearbox from excessive shock load
The original sunroof clutch is subjected to constant torsional load, vibration, and heat within the roof mechanism. Over time, the rubber coupling material can deteriorate, resulting in excessive play, slipping, noisy operation, or sunroof drive failure. Replacing a worn clutch restores reliable roof movement and helps prevent unnecessary stress on the sunroof motor and gearbox assembly.
When to replace
• Sunroof slips or stops moving intermittently
• Clicking or clunking noises from roof mechanism
• Excessive play within sunroof drive assembly
• Cracked or deteriorated rubber coupling
• During sunroof motor or gearbox servicing
• Preventative maintenance on ageing roof systems

OEMatch Coupe — Fit, Function, Confidence
OEMatch supplies a selection of Coupe roof panels and reinforcements for Porsche models, offering steel, aluminium and carbon-fibre options together with inner reinforcements, insulation and headliners to support structural repairs and restorations.
Available Types- Steel roof skins
- Aluminium roof skins
- Carbon-fibre roof skins
- Inner reinforcements and rails
- Sound insulation and damping
- Headliners and trim pieces
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original coupe. OE (Original Equipment) refers to parts matching original specifications for the coupe and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM coupe engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models. OEMatch maintains an extensive catalogue of items for Porsche Coupes, with thousands of cross-references and ongoing product development; offerings cover roof structure repair, noise control and interior renewal to assist restorations across multiple model years.
Benefits Include- Restores body rigidity and roofline integrity after damage or corrosion
- Protects the cabin from weather and reduces road and wind noise
- Prepares the body for paint and finishing by replacing corroded or deformed panels
- Accident or rollover damage to the roof skin and supporting structure
- Corrosion developing around drip rails, seams or mounting points
- Sun exposure and heat causing panel deterioration, fading or cracking
Replacing roof panels and their reinforcements restores structural form, seals the cabin against water ingress and prevents further corrosion that can affect adjoining bodywork. For Porsche models, correct panel geometry and compatible fixing points help achieve accurate gaps and secure mounting when preparing the vehicle for painting or long-term use.
Advantages- Direct-fit alternatives engineered to match original dimensions and tolerances
- A broad catalogue tailored to Porsche Coupes, aiding model-specific repairs
- Material options such as steel, aluminium and carbon fibre to suit restoration goals
These items affect safety-critical systems. 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 carrying out work at home, protect adjacent panels and trim, confirm correct mounting clips and seals, and recheck fasteners after initial running.
