Product Information
Product Information
Power steering pressure line
This OE Match power steering pressure line is a replacement hydraulic steering pipe used on Porsche 987.2 Boxster and Cayman models. It is designed to carry pressurised power steering fluid through the steering system, matching the original-style fitment and function.

Fits:
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.2 Cayman 2009 - 2012

Diagram ref no 7

The power steering pressure line transfers hydraulic fluid under pressure between the power steering pump and steering rack system. This hydraulic pressure assists steering movement, helping provide smooth, controlled and responsive steering operation.

Functions
Carries pressurised power steering fluid through the steering system
 Connects power steering components in the hydraulic circuit
 Supports smooth and assisted steering operation
 Helps maintain correct steering system pressure
 Replaces leaking, corroded, cracked or damaged original pipework
 Helps prevent power steering fluid loss and steering assistance failure
 OE Match replacement for correct fit and reliable steering performance

Why Replace This Part?
Power steering pressure lines are exposed to high hydraulic pressure, heat, vibration, road dirt and corrosion. Over time, the pipe or hose sections can crack, leak, rust, swell or fail at the fittings. A worn pressure line may cause fluid leaks, whining noises from the pump, heavy steering or loss of power steering assistance. Replacing the line helps restore proper hydraulic pressure and protects the steering system from damage caused by low fluid levels.

When to replace
•  Power steering fluid is leaking from the pipe or fittings
•  The line is corroded, cracked, swollen, kinked or damaged
•  Steering feels heavy or inconsistent
•  There is a whining or groaning noise from the power steering pump
•  Fluid level drops repeatedly after topping up
•   The steering rack or power steering pump is being replaced
•   The vehicle is undergoing steering system repair or maintenance
•   As preventative replacement when old hydraulic lines show signs of wear.

Where it fits on the car
This pressure line fits in the hydraulic power steering system on Porsche 987.2 Boxster and Cayman models. It forms part of the steering fluid circuit, routing pressurised fluid between the steering pump and steering rack area, depending on vehicle specification.

If you're serious about how your 996, 997, 986 Boxster, 987 Boxster, 987 Cayman, 991, 981 Boxster and 981 Cayman handles, you should upgrade the factory tie rods with an adjustable bump steer kit. There is one major drawback to the factory tie rods, bump steer. Bump steer results from a tie rod that is angled from the steering rack to the spindle. An angled tie rod end will have a larger horizontal travel distance than the rest of the suspension, compared to a level link. Rennline's adjustable bump steer kits solve this problem. Manufactured from 6061 aluminum and feature a turnbuckle design that allow each arm to be lengthened or shortened as needed to restore proper suspension geometry on a lowered Porsche. A number of spacers are also included and can be added or removed accordingly to get a level tie rod for your vehicles specific ride height. The FK Teflon-lined rod end bearings ensure precision handling and lock in your car’s alignment settings, ensuring predictable cornering under all conditions.

Note: 2 kits required per car. Rubber Boots not included but available separately.

Replacement stainless steel pipes for LHD (Left Hand drive) power steering rack
Other than buying a completely new steering rack or having your existing steering rack refurbished, which are both very expensive options, we now offer replacement steering rack pipes which are normally not available separately, the two replacement pipes fit to the steering rack, these pipes normally deteriorate. The steering rack of a power-assisted car needs a hydraulic circuit: a pressure line (high pressure) from the power steering pump (or pump + reservoir assembly) to the steering rack, and a return line (low pressure) from the rack back to the reservoir (or pump return side).

Product Information
Product Information
Steering rack boot clamping ring.
The Genuine Porsche 99951269309 is a clamping ring / boot clamp used in the steering rack assembly. This integral ring ensures the secure sealing and retention of the steering rack bellows (boots), protecting the inner tie-rod joints and rack mechanism from moisture, dirt, dust and road debris.
Sold each, 2 required per vehicle.

Fits:
Porsche 987.1 Boxster 2005 - 2008
Porsche 987.2 Boxster 2009 - 2012
Porsche 987C.1 Cayman 2006 - 2008

Porsche 997.1 2005 - 2008
Porsche 997.2 2009 - 2012
 
Diagram ref no 5

Position on Vehicle: Installed on the steering rack assembly; it clamps the rack-and-pinion boot (bellows) to the housing or tie-rod to maintain environmental sealing.

•  Applications: Ideal for replacing a degraded or missing clamp when the steering rack bellows have been replaced or when boot integrity has been compromised; essential for maintaining the sealed environment for the rack internals.

Though small, the clamping ring plays a crucial role in protecting your Porsche’s steering rack from contamination and wear. A loose, missing or corroded clamp allows dirt, water or debris to enter the bellows, which can accelerate wear and damage to the rack and tie-rod joints - leading to steering play or failure. Replacing it with the genuine Porsche part ensures proper sealing, longer rack life and consistent steering feel.

When to replace:
•  If the steering rack boot (bellows) is loosened, missing or has previously been replaced but the clamp was discarded.
•  When the clamp is visibly corroded, cracked or no longer secures the boot firmly.
•  During steering rack service, boot replacement or tie-rod replacement when the clamp is accessible.
•  On high-mileage vehicles where original clamps may have deteriorated or were previously reused.
•  To prevent potential steering rack contamination and maintain long-term system reliability.

Steering rack boot seal ring.
Located inside the steering rack housing (rack & pinion assembly) as an inner seal ring around gear housing/rack interface — critical for containing hydraulic fluid and ensuring rack integrity.
Sold each, 2 required per vehicle.

Fits:

Porsche 987.1 Boxster 2005 - 2008

Even though it’s a small part, the seal ring plays a vital role in your Porsche’s hydraulic steering system. When it fails, you may experience fluid leaks, loss of hydraulic assist, play in the steering or reduced feedback - all affecting handling, safety and longevity of steering components. Replacing the seal ring with the genuine part restores correct sealing, hydraulic pressure retention and the precise steering feel your Porsche expects.

When and why to replace:
Evident steering fluid seepage around the rack housing or boots, indicating internal seal failure.
Loss of power-steering assist or degraded steering feel, especially at low speeds or when cold.
During steering rack replacement or rebuild – when bearing access is available and you want to prevent future leaks.
As part of front-end or steering system overhaul on high-mileage vehicles where original seals may have aged or hardened.
Whenever the steering rack hydraulic system is opened or dismantled – fitting a new genuine seal ring ensures proper long-term service.

Common Porsche Steering Issues

Even the best-engineered Porsche components experience wear over time. Common steering problems include:

  • Low Power Steering Fluid- A frequent cause of heavy or unresponsive steering. Topping up fluid restores smoothness, but continual loss may indicate a leak.
  • Power Steering Leaks - If topping up fluid doesn’t solve the issue, check for leaks. Power steering fluid is usually clear or pink — look for patches under your car when parked.
  • Failing Steering Rack Mounts - Modern Porsches use rack-and-pinion systems. When rack bushings wear out, symptoms include - Jerky steering when going over bumps, Inconsistent wheel feel and Clunking, clicking, or popping noises in the column

If you notice any of these issues, it’s important to get your Porsche inspected by a specialist to prevent further damage.

Diagnosing & Replacing Porsche Steering Components

Steering issues are not always easy to diagnose without specialist knowledge. Our advice: book in with a Porsche specialist garage for a full inspection. They can pinpoint whether the issue is with the rack, joints, bushings, or hydraulics.

If replacement is required, our website makes it simple. Select your Porsche model and year, and we’ll filter the catalogue to show only compatible steering spares for your car.
