Bellows for Differential Locking Slave Cylinder
The Genuine Porsche Differential Locking Slave Cylinder Bellows (Part Number: 92833205105) is an original equipment protective seal designed for Porsche 928 models equipped with Porsche Sperr Differential (PSD) and Porsche 911 (964) Carrera 4 models with a differential locking system. Also known as the PSD Slave Bellows Seal, this flexible protective component fits around the differential locking slave cylinder actuator, helping protect the mechanism from dirt, moisture and external contamination.
Fits:
Porsche 928 S4 5.0 V8 1990–1991 4-speed automatic A2816+ (A28.16)
Porsche 928 GT 5.0 V8 1990–1991 5-speed manual G2855+ (G28.55)
* with PR:221 (M221) - Porsche electronically controlled limited-slip differential, known as PSD (Porsche Sperrdifferential)
Porsche 928 GTS 5.4 V8 1992–1995 5-speed manual G2857 (G28.57) 928
Porsche 928 GTS 5.4 V8 1992–1995 4-speed automatic A2818 (A28.18)
Porsche 911 (964) 1989–1994
* Application: Differential locking slave cylinder protective bellows
Diagram ref no
Manufactured to Porsche's original specifications, it provides precise fitment and reliable protection for the differential locking mechanism, making it an ideal replacement during differential or transmission maintenance.

* Application: Differential locking slave cylinder protective bellows
Diagram ref no
Manufactured to Porsche's original specifications, it provides precise fitment and reliable protection for the differential locking mechanism, making it an ideal replacement during differential or transmission maintenance.
This part supersedes the earlier Porsche part numbers 92833205102 and 92833205104.
What Does This Part Do? – Functions
- Protective Sealing: Helps protect the differential locking slave cylinder mechanism from contamination.
- Dirt and Moisture Protection: Prevents debris and moisture from entering the protected actuator area.
- Flexible Movement: Accommodates movement of the slave cylinder actuator.
- Component Protection: Helps reduce premature wear of associated differential locking components.
- Original Fitment: Maintains Porsche factory specifications and correct assembly.
Why Replace This Part?
Over time, the rubber bellows can become brittle, cracked or damaged due to ageing, heat and exposure to transmission fluids. A deteriorated bellows may allow dirt and moisture to reach the differential locking actuator, potentially causing wear or corrosion.
Replacing it with a genuine Porsche component helps restore protection to the slave cylinder mechanism and maintain the reliability of the differential locking system.
When to Replace This Part?
- Cracked Rubber: Visible splits, tears or deterioration.
- Fluid Leakage: Signs of oil or hydraulic fluid around the bellows requiring inspection.
- Loss of Flexibility: Rubber becoming hard, brittle or deformed.
- Differential Repairs: During slave cylinder or differential locking system servicing.
- Preventative Maintenance: When the original bellows shows signs of ageing or wear.
Where Does It Fit on the Car?
Location: Transmission / differential locking slave cylinder assembly.
The bellows is fitted around the differential locking slave cylinder actuator, located on the transmission or differential assembly.
- On compatible Porsche 928 models, it forms part of the rear transaxle's Porsche Sperr Differential (PSD) locking mechanism.
- On Porsche 964 models, it is associated with the lateral differential locking slave cylinder mounted to the transmission assembly.

Automatic Torque Biasing Differential enables your car to accelerate quicker and corner faster.

Quaife ATB Helical LSD differential for Porsche Boxter is suitable for Porsche Boxter models with 2.5 litre engine, model years 1996-98 only. A direct replacement for the standard Porsche differential, the Quaife ATB Helical LSD differential transforms your cars performance.
Unlike a conventional plate-style limited slip differential, the Porsche Boxter Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The Porsche Boxter Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Porsche Boxter Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks.
The Porsche Boxter Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication.
The Porsche Boxter Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards.
