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.

•  Position: Between steering rack housing and boot (bellows)
•  Function: Seals the interface to prevent fluid leaks and protect internal rack components

The O-ring can harden, flatten, or crack over time due to heat, fluid exposure, or age.

Replacement is recommended when:
•  Replacing or refitting steering rack boots
•  Servicing the steering rack or tie rod assemblies
•  Evidence of moisture, fluid seepage, or debris inside the bellows

Replacing with a Genuine Porsche N90180902 O-Ring ensures proper sealing, preventing premature wear or corrosion of internal steering components.
