Complete Strut Assembly Kit for Porsche 996 911 (Carrera 4 / 4S / Turbo)
Restore the precise ride quality and confident handling your 996 911 was built for. Over time, struts wear gradually under normal driving conditions, making changes in handling hard to notice until performance declines. This complete strut assembly kit includes nearly everything you need to replace your worn components and bring your suspension back to life.
Each kit includes:
- Front struts
- Strut mounts and bearings
- Bump stops
- Required hardware
With new struts installed, you’ll experience sharper handling, smoother ride quality, reduced braking distances, and more even tire wear.
Note: There are two available spring seat isolator sizes — 3.0mm (99634352500) and 6.5mm (99634352501) — sold separately. Please measure your existing isolator to ensure the correct size for your vehicle.
Additional information:
Coil springs are not included and can be purchased separately if needed.
Original washers and spacers can typically be reused, provided they show no signs of physical 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

What this product does:
• Provides a secure connection between the chassis and wheel hub
• Maintains wheel alignment for safe, predictable handling
• Absorbs suspension forces while keeping steering precise
Over time, control arms can bend, wear, or develop excessive play in the bushings and ball joints. This can cause uneven tire wear, knocking noises, wheel alignment issues, and a noticeable loss of steering precision. Replacement will restore the correct wheel alignment and suspension stability for which your Porsche was designed.

What This Product Does:
- The top mount (strut mount) sits between the top of the shock absorber/strut and the vehicle’s body/strut tower. It supports the loads from springs, damper, steering (via bearing), and absorbs vibration/road noise.
- A monoball mount version replaces the standard rubber mount with a spherical bearing (monoball) or very stiff mounting that provides more direct steering/suspension feedback, reduces deflection under load, and keeps suspension geometry (camber, caster) more consistent during hard cornering.
Symptoms & Signs You Need Replacement:
- Clunking or knocking noise from the top of the front strut tower when going over bumps or during steering inputs — a worn mount or bearing often causes this.
- Squeaking or creaking noise when steering the wheel, especially at low speeds — the strut mount bearing may be worn.
- Poor steering feedback or vague handling, especially when cornering hard — a worn mount can cause deflection and loss of camber control.
- Excessive vibration or noise through the body from the front suspension; worn mount rubber or bearing can transmit more noise.
- During a shock/strut replacement or front suspension overhaul — since the top mount assembly must be removed anyway, replacing the modern monoball upgrade kit is logical to restore or upgrade suspension quality.
- Steering geometry issues — if you’ve had camber/caster issues, or your tyres are wearing unevenly at the front, a poor top mount may contribute.
- Suspension performance & tyre contact: On high-performance cars like a Porsche 911 C4/Turbo, the front suspension’s geometry and mounting rigidity matter a lot. If the top mount is deflecting, you lose optimal tyre contact patch under load, which reduces grip, increases tyre wear, and impairs handling.
- Durability & noise/vibration: Rubber top mounts tend to degrade over time (cracking, flattening, absorbing road noise). A good mount + bearing kit eliminates unwanted compliance and noise, and lengthens life of the strut/damper assembly.
- Precise handling and steering feel: The top mount bearing allows the strut to turn with steering; if worn, you get sloppy steering feel and delayed response. Upgrading to a monoball mount helps sharpen the steering and gives more direct feedback.
- Prevents repeat labour: Since access to the strut top requires removing mount or taking down the strut, doing a mount/bearing replacement while everything is open is cost-effective. It avoids having to redo labour later when noise or wear returns.

Diagram Ref No 8, 9, 10, 11, 12, 13
What This Product Does:
- The strut mount (top mount) is the structural connection point between the top of the front shock/strut assembly and the car’s body (strut tower). It absorbs loads from the suspension (spring & damper) and allows the strut to pivot (for steering) via the bearing.
- The contact bearing or pivot bearing allows the front strut to rotate as the wheels are steered while maintaining smooth operation and minimal noise/fretting.
- Over time, the mount’s rubber cushion, metal plates or bearing can degrade, leading to noise, poor alignment, or less effective suspension function. The kit restores correct mount geometry, alignment, reduces unwanted movement, and improves ride/handling feel.
Symptoms & Signs You Need Replacement:
- Clunking or knocking noise from the top of the front strut tower when going over bumps or during braking/acceleration.
- Squeaking or groaning noise when turning the steering wheel – could indicate the bearing is worn.
- Excessive vibration or harshness coming through the body when driving, indicating the mount rubber may be fatigued.
- Uneven tyre wear or vague steering feel – if the strut mount is worn, the strut top may move under load, affecting geometry.
- During shock/strut replacement – because the mount is accessed when replacing the front shocks, it is wise to replace the mount/bearing at the same time to avoid future failure.
- Safety & handling: The strut mount plays a key role in the front suspension’s operation. A worn mount can compromise handling precision, ride comfort and may allow excessive movement under load.
- Noise, vibration & harshness: A deteriorated mount/bearing leads to unwanted noise and vibrations that degrade driving experience.
- Longevity of other components: If the mount is worn, the bearing, strut rod, or strut top plate may be overloaded, leading to premature failure of those parts. Replacing now can prevent larger issues.
- Cost-effective during service: Because the mount/bearing sits atop the strut, it typically requires partial suspension disassembly to reach. Replacing during suspension service is more economical than later doing mounts alone.

Porsche Suspension & Axle Parts
Porsche suspension systems are engineered with precision to deliver sharp handling, ride comfort, and maximum performance. Whether on the road or track, your Porsche relies on a finely tuned suspension and axle setup to keep you in control. When components wear out, the ride becomes rough, handling suffers, and safety can be compromised.
At Design911, we supply a full range of suspension and axle parts for classic and modern Porsche models — from shock absorbers and coil springs to control arms and ball joints - helping you maintain your car’s legendary driving dynamics.
Signs of Worn Shocks or Struts
Shock absorbers and struts are essential for keeping your
Porsche stable over bumps and through corners. Some signs they may need
replacement include:
- Excessive
Bouncing – car continues to bounce after hitting bumps
- Poor
Cornering Stability – leaning hard into corners, reduced grip
- Fluid
Leaks – damp or oily patches on shocks/struts
- Uneven Tyre Wear – poor damping leads to increased tyre wear
If left unchecked, worn shocks or struts not only reduce ride comfort but can also compromise safety.
Common Porsche Suspension Issues
Different Porsche models can face specific
suspension-related faults. The most frequent include:
- Lower
Track Control Arm Bushings - Failure
causes squeaking noises, uneven tyre wear, and eventually knocking sounds
over rough roads.
- Broken
Coil Springs - Seen
in models such as the Porsche Boxster. Symptoms include groaning noises
when steering and clicking or knocking over bumpy surfaces.
- Leaking
or Worn Shock Absorbers - Identified
by damp, oily residue on the shock body. This is one of the most common
suspension failures over time.
- Ball Joint Wear - Worn joints reduce steering precision and can lead to loss of control if ignored.
Fortunately, most of these issues can be resolved by simply replacing the affected parts with OEM or high-quality aftermarket components.
