Product Information
Product Information
Steering Rack Boot Clamp (crimp-type or “ear clamp”)
The Genuine Porsche N10551701 Boot Clamp is the factory clamp used to secure the steering rack bellows / rack boot to the rack housing or tie rod housing. This clamp ensures the boot is sealed tightly, keeping dirt, water, and debris out of the rack assembly and protecting internal steering components.
Sold each, 2 required per vehicle.

Fits:
Porsche Cayenne 955 2003 - 2006
Porsche Cayenne 957 2007 - 2010
Porsche Cayenne 958 2011 - 2017

Diagram ref no 3

•  Position: Around the boot (bellows) of the steering rack / inner tie rod connection
•  Function: Secures the rubber boot to the housing, maintaining a protective seal to prevent ingress of contaminants

The original clamp can lose tension, corrode, or break over time, leading to:
 Loose or leaking rack boots
 Entry of dirt, water, and debris into the rack
 Premature wear or damage to inner steering rack components

Replace the clamp when installing a new rack boot, after steering rack maintenance, or anytime a clamp looks old, stretched, or corroded. A new Genuine Porsche N10551701 clamp restores a secure, factory-level seal for reliable steering protection.

Product Information
Product Information
Steering Rack / Steering Gear, for vehicles with standard power-assisted steering, for LHD (Left Hand drive) cars.
This steering gear (rack & pinion / steering gear assembly) originally developed for the Porsche Cayenne (955/957) series. Its purpose is to convert driver steering-wheel inputs into controlled lateral movement of the front wheels, ensuring accurate directional control and stable handling. Built to original equipment standards and engineered for precise fitment, it delivers enduring performance, smooth steering and dependable durability.

Fits:
LHD (Left Hand drive) cars
Porsche 955 Cayenne 2003 - 2006
Porsche 957 Cayenne 2007 - 2010
*  for vehicles equipped with standard power-assisted steering (option code: 1N1), without “Servotronic” variant

Diagram ref no 1

   OE ref part numbers: 95534701104, 95534701106, 95534701108, 95534701110, 95534701112, 95534701114, 95534701120, 95534701121, 95534701122, 95534701124, 95534701125, 7L5422075X, 955347011AX,  955347011EX,
   Location: Front axle, steering rack assembly mounted beneath the front subframe, linking the steering column and tie rods.

The steering gear plays a vital role in ensuring precise handling and safe directional control. Over time, internal wear, seal failure, or corrosion can lead to fluid leaks, increased play, or heavier steering effort. A worn or leaking rack affects steering response, stability, and overall driving comfort. Replacing it with an OE-Match unit restores smooth operation, tight steering feel, and the factory performance your Porsche Cayenne was designed to deliver.

When and why to replace:
Noticeable looseness or vibration through the steering wheel.
Power-steering fluid leaks or visible damage to the rack housing.
Uneven steering effort or noise when turning.
Vehicle wandering or pulling despite correct wheel alignment.
During major suspension or front-axle service for full system refresh.
Preventative maintenance on high-mileage vehicles to avoid sudden failure and costly repairs.

We strongly recommend replacing the power steering pump at the same time as the steering rack. Swarf (metal particles) in the power steering system can circulate and cause damage to both components. If you choose to replace only the steering rack and, upon return of your exchange unit, we discover that the rack bar is scored or contaminated with swarf, this indicates that debris is present in the system. In such cases, we advise replacing the pump as well.
Please note: if we have advised that there is swarf in the system and you choose not to replace both components, any future warranty claims related to this issue will not be valid. 


The most common power steering faults are:
- Leaking power steering
- Torn Gators
- Hard to steering when idling
- Hard to steering one-way
- Steering-Wheel not self-centering
- Noise when Idling
- Noise when steering
- Judders when steering
- Loss of all power in steering
- Semi-Loss of power in steering
- Electric steering problems

Above are just some of the problems our customers are faced with on a day-to-day basis with their power steering units. We can replace your old unit with a Reconditioned unit. If we don't have a replacement available, we can take in your own unit and recondition it for you. Where a new unit can cost £100's we can recondition/supply reconditioned units at a fraction of this price!

All reconditioned racks come with 1 Year or 12,000 miles warranty!!


    PLEASE NOTE:
  • The surcharge for this reconditioned part will be refunded when the exchange unit is received and approved by us and the relevant manufacturer.
  • Please note, surcharge refunds often take an average of 6 to 8 weeks to be approved by the manufacturer.

About Steering Racks

Porsche Steering Racks | Design911 Precision Steering Assemblies for Control & Performance

The steering rack is the heart of your Porsche’s steering system — translating driver input from the steering wheel into precise directional movement of the wheels. It’s a critical component that ensures responsive handling, stability, and control under all driving conditions. Whether your Porsche uses a hydraulic, manual, or electric power steering setup, maintaining a smooth and accurate rack assembly is essential for both performance and safety.

At Design911, we supply a complete range of steering racks, including hydraulic, electric, and manual systems for both classic and modern models. Each unit is built to high engineering standards, providing exceptional steering feel, precision, and reliability. Perfect for routine servicing, performance restoration, or full rebuilds, our racks ensure your Porsche handles exactly as it was designed to — sharp, smooth, and predictable.

What Do Steering Racks Do?

The steering rack converts the rotational motion of the steering wheel into linear movement, controlling the vehicle’s front wheels for directional accuracy.

Core Functions:
• Transfer steering input into smooth, precise wheel movement.
• Work in conjunction with the power steering system for ease of control.
• Maintain correct wheel alignment and tracking.
• Provide balanced feedback and road feel.
• Ensure stability and steering accuracy at all speeds.

A properly functioning steering rack delivers confidence-inspiring handling — from high-speed motorway cruising to tight cornering on track.

Why Do Steering Racks Fail or Degrade?

Steering racks experience constant pressure, movement, and exposure to heat and contaminants, leading to gradual wear over time.

Common Causes of Failure Include:
• Seal wear leading to hydraulic fluid leaks.
• Corrosion or pitting on internal rack surfaces.
• Play or looseness in steering due to worn bushings or joints.
• Power steering fluid contamination causing internal damage.
• Age-related degradation in gaskets or mounts.

When steering racks begin to fail, symptoms include excessive play, vibration, fluid leaks, uneven steering effort, or knocking noises — all signs that replacement or refurbishment is required.

Why Replace or Upgrade Your Porsche Steering Rack?

Replacing or upgrading your steering rack restores handling precision, stability, and steering feedback. Modern or performance-oriented replacements offer improved durability and response for both road and motorsport use.

Key Benefits:
• Restores sharp, responsive steering performance.
• Eliminates fluid leaks and unwanted play.
• Improves road feel and vehicle stability.
• Available in manual, hydraulic, and electric configurations.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Panamera, and Cayenne models.
