Porsche 996 911 Carrera Rear Shock Absorber Kit  Fits cars WITHOUT M030 sports suspension.

Restore the precise ride quality and confident handling your Porsche 996 911 Carrera was built to deliver. Over time, shocks gradually wear down, making changes in handling and comfort hard to notice until performance begins to fade. This complete shock absorber kit includes nearly everything you need to replace your worn components—shock mounts, bump stops, dust boots, and all necessary hardware. 

bilstein

Fits:
Porsche 996 3.4L Carrera
Porsche 996 3.6L Carrera
Porsche 996 3.6L Carrera S
Porsche 996 3.4L Carrera 4,
Porsche 996 3.6 Carrera 4,
Porsche 996 3.6 Turbo,
Porsche 996 3.6 Turbo S


With fresh shocks installed, you can expect:

Sharper, more responsive handling Improved ride comfort and stability Reduced braking distances More even tire wear

Note: Coil springs are not included and can be purchased separately if needed. The original washers and spacers can typically be reused unless they show signs of damage upon inspection.

B4 High Quality direct replacement shock absorbers constructed and finished to Bilstein's high standards often far and above what the car was originally supplied with. They can actually be a performance improvement if replacing plain, none gas charged, oil filled dampers. They dramatically reduce cavitation / oil foaming, thus give for more stable damping forces when driven 'spiritedly'. Some surprising cars come with plain oil filled dampers.

Key Features:
- Twin Tube Damper
- Gas pressurized
- OE damping forces

About Bilstein standard

Porsche Bilstein standard

The Bilstein B4 range is Bilstein’s OEM-equivalent suspension for Porsche models, designed to deliver the character and comfort of the factory setup with the quality and durability of a brand used by many vehicle manufacturers as original equipment. For Porsche owners, B4 dampers are an excellent choice when you want the car to feel “right” again on the road without changing its basic ride or handling balance.

Bilstein B4 for Porsche – what it is

Bilstein B4 shock absorbers are developed as direct-replacement units for standard suspension on many Porsche models. They are engineered to match original equipment specification and work with standard springs and factory geometry.

  • Designed as an OEM-equivalent replacement for standard suspension
  • Engineered to work with original Porsche springs and mounting hardware
  • Valving and damping curves tuned for everyday road use
  • Available in application-specific twin-tube or monotube designs
  • Intended for standard-height, non-extreme, everyday driving

Depending on the Porsche model, Bilstein uses either its proven monotube gas-pressure design or a high-quality twin-tube layout, chosen to suit the packaging and performance requirements of that particular application.

How Bilstein B4 behaves on the road

On a Porsche with tired or ageing dampers, fitting Bilstein B4 typically brings the car back towards its intended feel on normal roads. The emphasis is on predictable, secure behaviour rather than aggressive sport tuning.

  • Comfort-focused damping for daily driving and commuting
  • Calm, controlled response over bumps and poor surfaces
  • Stable support under braking and acceleration in normal use
  • Balanced ride/handling compromise similar to factory specification
  • Suitable for standard wheels, tyres and road-focused setups

For most owners, the result is a Porsche that feels refreshed and reassuring without becoming noticeably harsher than stock.

Typical Porsche use-cases for Bilstein B4

  • Replacing worn original dampers while keeping a standard ride
  • Refreshing suspension on a daily-driven Porsche or long-distance car
  • Maintaining factory character on classic and modern Porsche models
  • Retaining standard ride height while improving control compared with tired units
  • Providing a quality branded alternative to basic pattern dampers

If you drive mainly on public roads and want your Porsche to feel close to how it left the factory, Bilstein B4 is usually the most appropriate Bilstein option. For lowered springs or more focused fast-road/track use, other Bilstein lines such as B6 or B8 are typically chosen instead.

Key characteristics of Bilstein B4

  • Original equipment-level development and testing
  • Gas-pressure technology on most applications for consistent response
  • Application-specific valving tailored to each vehicle platform
  • Designed to integrate with existing suspension hardware
  • Built with corrosion-resistant finishes and high-quality sealing

Because B4 is an OEM-equivalent line, the focus is on long-term reliability and consistent behaviour over many miles of everyday driving.

Who Bilstein B4 suits best on a Porsche

  • Owners prioritising comfort and refinement over maximum stiffness
  • Drivers who mainly cover road miles rather than regular circuit use
  • People restoring a Porsche to a near-original driving feel
  • Those looking for simple, like-for-like replacement without complex setup
  • Owners wanting reputable-brand quality within a standard-style package

Matched correctly to your model and fitted with good mounts, top bearings and bushes, a fresh set of Bilstein B4 dampers can make a well-maintained Porsche feel tidy, composed and easy to live with again.

Installation and pairing considerations

  • Best fitted in axle pairs (both fronts together, both rears together)
  • Intended for use with standard springs and factory ride height
  • Often combined with new top mounts, bump stops and dust covers on higher-mileage cars
  • Geometry check and alignment recommended after fitting
  • Check other suspension components (bushes, arms, links) at the same time

Noise or poor behaviour after fitting new dampers is often traced to worn mounts, drop links or bushes rather than the new B4 units themselves, so an overall inspection is sensible during the work.

Why choose Bilstein B4 for your Porsche?

  • Developed by a long-established suspension specialist used by many vehicle makers
  • Preserves the everyday usability and comfort of a standard Porsche
  • Designed as a direct-fit solution for the relevant Porsche model
  • Suitable for standard road use, commuting and touring
  • Provides a clear, quality-focused alternative to generic replacement dampers

For Porsche drivers who simply want their car to feel sorted and confidence-inspiring on everyday roads, Bilstein B4 sits at the sensible, OEM-style end of the suspension spectrum: a straightforward, model-specific solution with a focus on comfort, stability and familiar Porsche character.
