Vehicle Repairs. We've Got What It Takes.
The febi range of high-quality, specialist hydraulic oils provide optimised low-temperature performance. They are based on advanced additives and selected mineral base oils, and are developed specifically for use in central hydraulic systems such as power steering, convertible roof mechanisms and hydro-pneumatic suspension systems.

Quality by Conviction:
Oils from febi are not universal products, but rather are tailored to the special requirements of vehicle manufacturers. Only the right oil can guarantee the safe functioning of the hydraulic systems in the vehicle. High-quality hydraulic fluids from febi are therefore precisely matched to the special requirements of vehicle manufacturers.

Steering rack gaiter kit
TRW steering rack gaiter kit for Porsche 986 Boxster and 996 models equipped with the early steering rack. Suitable for the left and right front axle positions and supplied with accessories.
One kit per car required

Fits
Porsche 986 Boxster 1997 - 2004
Porsche 996 1998 - 2005


Please note
Fitting Position: Front Axle left and right,
For OE Steering Rack No.: 996.347.011.05, 996.347.012.05
Inner Diameter 1: 12,3 mm, Inner Diameter 2: 48 mm, Height: 195,3 mm, With accessories



What This Product Does

The flexible bellows cover the moving rack ends and inner steering joints. They help exclude road grit and moisture while accommodating steering movement and keeping lubrication protected.


Functions

  • Shield the covered steering components from contamination.
  • Accommodate movement as the steering operates.
  • Help protect lubricated inner joints from moisture exposure.


Symptoms of Fault

  • Visible cracking, punctures or tears in the bellows.
  • Loose attachment or contamination around the gaiter ends.
  • Moisture or dirt found beneath the protective cover.
  • Knocking where an exposed inner joint has developed wear.

Steering noise or looseness can have several causes. Inspect the rack and joints rather than assuming a replacement gaiter will resolve existing mechanical wear.


Why Replacement Matters

A damaged or poorly secured gaiter leaves the covered components exposed to water and abrasive debris. Renewing it restores the protective barrier, but cannot repair a worn joint or leaking rack. Check the inner joint and attachment points during the work.


FAQs

Will this fit every listed vehicle?
Confirm the installed rack reference: this kit is intended for the early rack specification.

Is alignment needed afterwards?
Have the wheel alignment checked if track rods are disturbed or their adjustment changes.

What should be inspected with the gaiter removed?
Check for inner-joint play, contamination and signs of rack leakage before fitting the replacement cover.

Steering rack gaiter kit
TRW steering rack gaiter kit for Porsche 986 Boxster and 996 models fitted with the specified later steering racks. Accessories are included for the front axle's left and right sides.
One kit per car required

Fits
Porsche 986 Boxster 1997 - 2004
Porsche 996 1998 - 2005

Please note
Fitting Position: Front Axle left and right,
For OE Steering Rack No.: 996.347.011.06, 996.347.011.07, 996.347.012.07, 996.347.012.08
Inner Diameter 1: 12,3 mm, Inner Diameter 2: 52 mm, Height: 195,3 mm, With accessories


What This Product Does

The bellows cover the moving rack ends and inner steering joints, helping exclude moisture and road debris while accommodating steering movement.


Functions

  • Shield covered steering components against contamination.
  • Maintain a flexible protective enclosure as the rack moves.
  • Help protect inner joints from exposure when correctly secured.

Symptoms of Fault

  • Visible tears, punctures or cracking in the bellows.
  • Loose attachment points or contamination beneath the gaiter.
  • Moisture entering the covered joint area.

Knocking or steering play warrants inspection of the joints and related components rather than assuming the gaiter alone is responsible.


Why Replacement Matters

A damaged or unsecured gaiter leaves the enclosed components exposed. Renewing it restores the protective covering, but any existing joint wear also needs assessment.


FAQs

How many kits does a vehicle need?
One kit per car required.

How do I confirm suitability?
Match the fitted steering rack number against the four OE rack references above.

Is alignment needed afterwards?
Have the alignment checked if track rods or steering adjustment settings are disturbed during installation.

What should be inspected during replacement?
Check the exposed inner joints for contamination and excessive play before fitting the new bellows.

About Steering Gaiter

Porsche Steering Gaiters | Design911 Protective Boots for Steering Racks & Suspension Systems

Steering gaiters — also known as rack boots or bellows — are critical for protecting the moving parts of your Porsche’s steering and suspension systems. These flexible rubber or thermoplastic sleeves shield steering rack joints and components from dirt, water, and debris while retaining essential lubrication. Properly functioning gaiters prevent premature wear, corrosion, and mechanical failure, ensuring your Porsche delivers the precise, responsive handling it was engineered for.

At Design911, we supply a comprehensive range of steering gaiters designed for perfect fitment and long-term protection. Manufactured from durable, heat- and ozone-resistant materials, our gaiters provide superior flexibility and sealing performance. Ideal for maintenance, restoration, or performance servicing, they help preserve the accuracy and longevity of your steering system under all driving conditions.

What Do Steering Gaiters Do?

Steering gaiters protect the inner workings of your Porsche’s steering rack and joints, maintaining smooth movement and preventing contamination.

Core Functions:
• Protect steering rack components from dirt, grit, and moisture.
• Seal lubricants inside the steering assembly to reduce friction.
• Prevent corrosion and extend the life of steering joints.
• Allow full steering articulation while maintaining a tight seal.
• Reduce wear and vibration within the steering mechanism.

A high-quality steering gaiter is essential for keeping your Porsche’s steering smooth, quiet, and responsive — both on the road and track.

Why Do Steering Gaiters Fail or Degrade?

Over time, steering gaiters experience wear from motion, environmental exposure, and heat, which can lead to cracking or splitting.

Common Causes of Failure Include:
• Age-related hardening or cracking of rubber material.
• Heat, oil, or road salt exposure causing deterioration.
• Punctures from debris or rough terrain.
• Improper installation leading to loose seals.
• Extended use without inspection or maintenance.

When a gaiter fails, contaminants can enter the steering rack, causing corrosion, fluid leaks, or excessive play — potentially leading to costly steering repairs.

Why Replace or Upgrade Your Porsche Steering Gaiters?

Replacing damaged or worn steering gaiters is a cost-effective way to prevent major steering system damage and maintain precise handling. Upgraded materials provide better resistance to heat, chemicals, and environmental wear.

Key Benefits:
• Protects steering rack from dirt, moisture, and corrosion.
• Extends the lifespan of seals, joints, and lubricants.
• Reduces maintenance costs and prevents fluid leaks.
• Available for classic and modern Porsche models, including 911, 944, 968, Boxster, Cayman, and Cayenne.
• Precision-engineered for exact fitment and long-term durability.
• Ideal for restoration, maintenance, or performance servicing.

Design911’s Porsche steering gaiters combine robust materials and accurate fitment — ensuring your Porsche continues to deliver safe, responsive, and reliable steering performance.

Highlights

• Premium Porsche steering gaiters and rack boots.
• Constructed from high-strength rubber or thermoplastic.
• Designed for excellent sealing and long service life.
• Resistant to oil, heat, and road contaminants.
• Precision-fit replacements for classic and modern models.
• Perfect for maintenance, restoration, or performance upgrades.
