The shock absorber for those drivers who prefer a sports suspension but are not particularly interested in lowering the body. Also available in special design complete with reservoir for off-road vehicles.
No risk, more fun
For some people it's important to show what they have, for others it's sufficient to know that they have it. The theme of the discussion here is the sports suspension. The BILSTEIN B6 Sports shock absorber is the ideal solution for drivers revelling in the understatement . The wolf in sheep's clothing snarls, when necessary, but otherwise goes reliably about its work in daily traffic with no lowering of the body whatsoever.

Optimum road holding, enhanced tracking stabilisation and excellent damping force: the BILSTEIN B6 Sports is not only first choice as far as sports tuning is concerned but also in the sphere of safety.

BILSTEIN Replacement for the Original Spec

Fits:
Porsche 991.1 & 991.2 
- For vehicles without PASM
- For vehicles without leveling control
- For vehicles with standard chassis
- For vehicles without electronic suspension control

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

Please Note:
Price is for each damper you will need to buy 2

About Shock Absorbers REAR

Porsche Rear Shock Absorber Parts | Design911 Suspension Components for Ride Stability, Comfort & Handling Control

Rear shock absorber parts play a vital role in maintaining your Porsche’s balance, ride comfort, and handling precision. These components support the rear suspension system, absorbing impacts and ensuring the vehicle remains stable under acceleration, braking, and cornering. From top mounts and bearings to bump stops, dust covers, and hardware, every component contributes to the consistent damping and ride quality that define Porsche performance.

At Design911, we supply a comprehensive range of rear shock absorber parts, precision-engineered for durability, alignment accuracy, and long-term reliability. Whether you’re carrying out routine maintenance, full suspension restoration, or performance upgrades, our parts help maintain perfect damping control and ensure your Porsche drives as smoothly and confidently as intended.

What Do Rear Shock Absorber Parts Do?

Rear shock absorber components ensure proper damper function and suspension support, allowing the rear axle to move fluidly while maintaining grip and control.

Core Functions:
• Support the rear shock absorber and maintain correct alignment.
• Absorb road vibrations for smoother ride comfort.
• Reduce body movement and improve handling balance.
• Protect suspension components from dirt and debris.
• Ensure stable damping under high-load or performance driving.

Together, these parts keep your Porsche’s rear suspension responsive, refined, and stable — essential for performance driving and everyday comfort alike.

Why Do Rear Shock Absorber Parts Fail or Degrade?

Over time, exposure to heat, vibration, and road conditions causes suspension components to wear and lose effectiveness.

Common Causes of Failure Include:
• Worn rubber or polyurethane bushings and mounts.
• Corroded bolts or degraded hardware.
• Cracked dust covers allowing contamination into the damper.
• Damaged bearings or perished top mounts.
• Fatigue from prolonged exposure to road stress or track use.

Failure of these components can cause rear-end instability, clunking noises, poor ride comfort, and uneven handling — all clear signs replacement is needed.

Why Replace or Upgrade Your Porsche Rear Shock Absorber Parts?

Replacing worn or damaged rear shock absorber parts restores suspension geometry, damping efficiency, and comfort. Upgraded performance components improve ride stability, response, and long-term reliability.

Key Benefits:
• Restores smooth ride and consistent damping.
• Improves handling precision and rear suspension balance.
• Reduces noise, vibration, and harshness.
• Manufactured from high-quality, corrosion-resistant materials.
• Fits Porsche 911, 944, 968, Boxster, Cayman, Panamera, Cayenne, and Macan models.
• Perfect for servicing, restorations, or suspension performance upgrades.

Design911’s Porsche rear shock absorber parts deliver strength, precision, and quality — keeping your Porsche composed, comfortable, and confident on every drive.

Highlights

• Premium Porsche rear shock absorber mounts, bearings, and hardware.
• High-quality materials for long-lasting performance.
