Bilstein
Porsche Bilstein suspension
The core BILSTEIN brand can look back on a 140-year history. When the company was founded in Altenvoerde (now Ennepetal) in 1873, no one imagined how strongly its products would later influence road comfort and control. Driving dynamics is the company’s focus: realising precise, predictable behaviour and building high-quality Porsche shock absorbers and suspension components. That philosophy underpins the Bilstein range available for Porsche models at Design911
Common options & kits
Individual replacement parts Specific items to address a particular area or issue without changing everything at once.
- Ideal for targeted repairs
- Lets you replace only what is needed
- Helps keep initial costs under control
- Consistent feel and performance
- Helps avoid uneven wear or behaviour
- A sensible choice for routine maintenance
- Everything specified in a single package
- Saves time compared with sourcing parts individually
- Ideal when upgrading or restoring your Porsche
When should you review or replace suspension on your Porsche?
Checking shock absorbers regularly helps you spot wear, damage or age-related deterioration before it affects comfort, refinement or leads to more expensive repairs later on.
- Existing parts are worn, cracked, scuffed, faded, corroded or missing
- You notice looseness, vibration or an untidy appearance around the area they sit in
- You have had related work carried out and want everything to look and feel consistent
- You want the car to feel smarter and better cared for in daily use or before resale
If any of these apply, it is a good time to review your suspension and replace anything that is past its best so your Porsche stays dependable and enjoyable to drive.

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

Bilstein B6 front shock absorbers and fittings set for Porsche Boxster 986 models (2.5, 2.7 and 3.2 S) from 09/1996, suitable for cars with standard suspension or the M030 sport option.
What This Product Does
Bilstein B6 dampers are uprated gas-pressure shock absorbers developed to work with standard ride height on many Porsche applications. On a Boxster 986, they are commonly chosen to tighten body control and improve composure compared with tired original dampers while remaining appropriate for everyday road use.
Functions
- Controls front suspension movement over bumps and uneven surfaces
- Works with existing springs to support correct ride height and geometry
- Helps maintain tyre contact with the road during braking and cornering
- Limits excessive pitch and roll caused by worn or ageing dampers
- Contributes to predictable steering response when the chassis is in good condition
- Integrates with original-style mounts and hardware where specified
Symptoms of Fault
- Front end feels floaty, bouncy or slow to settle after bumps
- Notable dive under braking or increased body roll
- Knocking noises from the front, once mounts and bushes have been checked
- Uneven or accelerated front tyre wear linked to poor damping
- Visible leaks, corrosion or damage on existing front dampers
- Car feels less stable in quick direction changes than expected
Why Replacement Matters
- Ageing front dampers are common on Boxster 986 models and can make the chassis feel loose even if other components are sound
- Refreshing front shock absorbers is a frequent step when owners restore steering precision and overall suspension condition
- Replacing tired units at the same time as arms, bushes and top mounts helps avoid repeat labour and inconsistent behaviour
- Using application-specific Bilstein units supports correct fitment on Porsche platforms
- Maintaining effective damping at the front axle is important for balanced braking and predictable handling characteristics

FAQs
- Q: Can these be used with standard springs?
A: Bilstein B6 dampers are generally intended to work with standard-ride-height springs on many Porsche models; confirm against the specific application details. - Q: Do both front dampers need to be replaced together?
A: It is usual practice to renew dampers in axle pairs so left and right sides behave consistently. - Q: Is an alignment check recommended after fitting?
A: Geometry should normally be checked after suspension work to confirm correct settings. - Q: Should top mounts and bushes be changed at the same time?
A: Many owners replace worn mounts and associated hardware during damper replacement to reduce noise and make the most of the new parts.
Support & Advice
Check fitment for your specific Boxster 986 (model year, engine and suspension option) before ordering, and inspect related suspension components so any additional wear can be addressed during the same job.

Bilstein Sprint B8 front & rear shock absorber – Porsche 996 C2 1997–2005 by Bilstein for Porsche 996 C2 models with sports suspension or lowered springs. The B8 Sprint is a shortened damper option intended for reduced ride height applications, using Bilstein suspension know-how for Porsche fitment.
What This Product Does This front and rear shock absorber set supports damping control on compatible Porsche 996 Carrera 2 models where sport suspension or lowering springs are fitted. The shortened B8 design is commonly used where standard-length dampers are not the intended match for reduced suspension travel.
Functions
- Provides front and rear damping for suitable Porsche 996 C2 applications.
- Works with sports suspension or lowered spring setups.
- Supports suspension travel suited to reduced ride height.
- Helps maintain consistent damping when related units are renewed together.
- Forms part of a suspension refresh or lowered suspension configuration.
Symptoms of Fault
- Floaty ride or weak rebound control.
- Increased body roll or braking dive.
- Bouncing, instability or poor composure over bumps.
- Uneven or cupped tyre wear.
- Visible oil leakage, corrosion or physical damage on the damper body.
- Knocking or clunking, noting that mounts, bushes or links may also be the cause.
- Bottoming out or harshness on a mismatched lowered setup.
Why Replacement Matters
B8 dampers are typically chosen for use with lowering springs because they are designed around reduced ride height and travel. Replacing tired dampers can help restore intended suspension control, but related mounts, bushes and links should be checked at the same time. Wheel alignment is normally required after suspension work.

- 996 (911) (1997–2005) => 996 C2 3.6L 09/01–2005
Check fitment for your specific vehicle, including model, year and engine, before ordering.
FAQs
- Q: B6 or B8? A: B6 is generally used with standard springs; B8 is commonly selected for lowered springs.
- Q: Is alignment required? A: Yes, alignment should be carried out after suspension work.
- Q: Should other parts be replaced at the same time? A: Inspect mounts, bushes and links, as worn supporting parts can affect the result.
- Q: Will a lowered setup feel firmer? A: It can, depending on the springs, damper condition, ride height and geometry.

Bilstein Sport B6 rear shock absorbers and top mounts kit by Bilstein for Porsche 996 C2 models from 1997–2005. This rear suspension package is intended for cars using standard springs and is listed for models without sports suspension.
What This Product Does The kit renews the rear dampers and upper mounting points. Bilstein B6 dampers use gas-pressure technology and application-specific valving, with the B6 line commonly selected for standard ride height road applications.
Functions
- Replaces rear shock absorbers and top mounts together.
- Supports matched damping across the rear axle.
- Works with suitable standard springs where the application allows.
- Helps address worn, leaking or corroded rear dampers.
- Avoids pairing renewed dampers with aged upper mounts.
Symptoms of Fault
- Floaty or unsettled ride after bumps.
- Poor rebound control or excess body movement.
- Increased roll or pitch compared with normal behaviour.
- Uneven tyre wear or tyre cupping.
- Rear suspension knocking, which may also come from mounts, bushes or links.
- Visible damper leakage, corrosion or damage.
Why Replacement Matters Rear dampers and top mounts wear with age and mileage. Replacing them as a rear kit can help restore consistent suspension operation and reduce the likelihood of noise from old mounting parts. After suspension work, wheel alignment should be checked.
Fits
- Porsche 996 (911) (1997–2005)
- Porsche 996 C2 3.4L (1997–08/01)
- Porsche 996 C2 3.6L (09/01–2005)
Check fitment for your specific vehicle, including model, year, engine and suspension specification, before ordering.
FAQs
- Can B6 dampers be used with standard springs? Often yes, depending on the specific application. This listing is for standard spring applications without sports suspension.
- B6 or B8? B6 is generally used with standard springs, while B8 is commonly selected for lowered springs.
- Is alignment needed after fitting? Yes, alignment should be checked after suspension work.
- Should mounts be renewed at the same time? Renewing mounts with dampers is a sensible approach where mounts are worn or aged.

Bilstein Shock absorbers rear strut and mounting kit for the rear of Porsche 964 models from 12/1988 to 12/1990 mounting parts by OE Match, covering 964 (911) Carrera 2 and Carrera 4 applications and allowing multiple rear suspension components to be renewed together for consistent fit and behaviour.
What This Product Does Provides the key rear damper and strut mounting components so the rear shock absorbers are correctly located on the Porsche 964 chassis. It supports proper damper alignment, helps manage noise and vibration from the rear suspension, and reduces the likelihood of premature wear caused by tired mounts, bump stops or hardware.
Kit Includes
2 x Shock absorber strut mounting (96433306404)
2 x Rear shock absorber (24-017350) Bilstein
2 x Hexagon nut (99908462101)

2 x Shock absorber top mount rubber insert (96433306903)
2 x Shock absorber bump stop (92833351810)
2 x Shock absorber dust cover (96433350201)
2 x Washer (91133351100)
2 x Shock absorber supporting cover (92833355100)
Functions
- Mounts the rear shock absorber securely to the body and suspension
- Helps control damper movement and impact loads through the rear axle
- Supports correct operation of the rear suspension geometry
- Assists in reducing knocks, rattles and harsh impacts from the rear damper area
- Provides matched mounts, bump stops, covers and hardware for the rear shocks
Symptoms of Fault
- Knocking or rattling noises from the rear suspension area
- Harsh or sharp impacts over bumps where bump stops or mounts have deteriorated
- Unsettled, vague or unstable feel from the rear of the vehicle
- Visible cracking, perishing or distortion in rear shock mounts, inserts or hardware
- Signs of premature rear damper wear or movement at the mounting points
Why Replacement Matters Rear damper mounting parts on the 964 are often refreshed at the same time as new rear shock absorbers to avoid reusing aged top mounts, bushes or hardware that can undermine damping control. An OE Match kit allows several related rear suspension parts to be replaced together so components are compatible with each other and with the intended Porsche specification. This approach can help maintain consistent rear axle behaviour on both Carrera 2 and Carrera 4 models as they age, while reducing the chance that worn supporting parts cause noise or accelerated wear on new dampers.
Fits
- Porsche 964 (911) (1989–1994)
- Porsche 964 (911) C2 1989–93
- Porsche 964 (911) C4 1989–93
FAQs
- Q: Is this type of kit vehicle-specific?
A: Kits of this kind are usually specified for particular Porsche models and production years, so confirm coverage for your 964 (including model year and Carrera 2/Carrera 4 variant) before use. - Q: Does a kit like this normally include all one-time-use hardware?
A: Not in every case. Use the listed or supplied contents to verify whether additional bolts, clips or other hardware need to be sourced separately. - Q: Any installation tip for suspension kits on a 964?
A: Compare the kit contents against the relevant Porsche PET diagram and your planned work so you know exactly which mounts and fixings are included and what else you may wish to renew while access is available.

Why Replacement Matters
On Porsche 964 models the rear struts, mounts and related hardware are subject to continuous load, movement and exposure to the elements. Over time, rubber parts can harden or split and metal components can corrode or wear, leading to noise, reduced damping control and less precise geometry. Replacing mounts, bump stops, dust covers and hardware alongside new rear dampers is a common approach on these cars, helping to avoid reusing tired parts and reducing the likelihood of repeat labour if noises or play remain after damper replacement.

- FAQs
- Q: Should rear strut mounts and hardware be renewed with new rear dampers?
A: They are commonly replaced at the same time, especially if original or showing wear, to avoid reusing aged mounts and fixings. - Q: Could rear knocking come from components other than the shock absorber itself?
A: Yes, rear top mounts, drop links and suspension bushes are frequent sources of knocks and should be checked together. - Q: Any practical tip when using a complete kit like this?
A: Compare the kit components with the Porsche parts diagram and your existing hardware before starting work so you understand what is included and what may still be required.
