At Design911, we supply high-quality hydraulic cylinders manufactured using advanced materials and precision seals, these cylinders are designed to withstand the hydraulic pressures and temperature variations encountered in everyday use.

Whether you’re restoring a Cabriolet roof system or replacing a leaking unit, this part ensures dependable operation and preserves your Porsche’s refined driving experience.

What Does a Hydraulic Drive Cylinder Do?
The hydraulic drive cylinder is responsible for powering the motion of your Porsche Cabriolet roof through hydraulic pressure.

Core Functions:

• Converts hydraulic fluid pressure into mechanical movement to raise or lower the roof.
• Ensures smooth, balanced motion between both roof sides.
• Maintains alignment and tension of the roof mechanism.
• Works in tandem with pumps, lines, and valves for seamless operation.

Without a functioning cylinder, the roof system cannot move properly, often resulting in uneven motion or complete failure.

Why Do Hydraulic Cylinders Fail or Leak?
Over time, wear, heat, and hydraulic pressure take their toll on the seals and internal components.

Common Causes of Failure Include:

• Hydraulic fluid leaks from worn or cracked seals.
• Contamination or debris damaging the internal piston.
• Age-related degradation of rubber components.
• Air ingress into the hydraulic system causing pressure loss.
• Corrosion or mechanical damage from extended use or storage.

When a cylinder fails, symptoms can include slow or jerky roof operation, fluid leaks in the rear compartment, or complete hydraulic system failure.

Why Replace Your Porsche Hydraulic Drive Cylinder?
Replacing your hydraulic drive cylinder restores full convertible roof functionality and protects the entire hydraulic system from strain or damage.

Key Benefits:

• Restores smooth, reliable Cabriolet roof operation.
• Prevents hydraulic leaks and loss of pressure.
• Protects pumps and lines from premature wear.
• Precision-engineered for Porsche 996 and 997 fitment.
• Manufactured using high-grade seals and corrosion-resistant materials.
• Designed to perform under high hydraulic load and temperature variation.

Replacing worn hydraulic cylinders ensures your roof operates as intended — with quiet, consistent, and leak-free performance.
