I really dont think thats the case as its such a big difference. The bouncy suspension was literally my favorite thing about my car since I bought it. I hate a rough ride.
Also this is the AI search comparison results I looked at before I decided to switch the Bilsteins out for the Sachs.

"When choosing between Bilstein and Sachs shocks and struts, the decision largely depends on your driving preferences, vehicle type, and desired balance between comfort and performance. Both brands are reputable and often used as OEM (Original Equipment Manufacturer) parts for various vehicles, particularly German makes like BMW, Mercedes-Benz, and Audi. Below is a comparison based on key factors, incorporating insights from automotive forums and user experiences:
Overview
- Bilstein: Known for German engineering, Bilstein shocks and struts are often associated with sportier, firmer rides and superior handling. They are popular in performance-oriented applications and are available in multiple lines (e.g., B4, B6, B8) to suit different needs.
- Sachs: Also a German brand, Sachs is a common OEM supplier for many European vehicles. They are typically designed for comfort and durability, offering a smoother, more compliant ride that closely matches factory settings.
Key Differences
- Ride Quality:
- Bilstein: Generally firmer, especially with their performance lines like B6 (Heavy Duty) and B8 (Sport). The B4 (Touring Class) is closer to OEM ride quality but may still feel slightly stiffer than Sachs. Users note that Bilstein shocks, particularly B6 and B8, reduce body roll and improve handling but can feel harsh on rough roads or potholes, especially in sport suspensions.
- Sachs: Prioritizes comfort, providing a softer, more cushioned ride that’s ideal for daily driving or long-distance cruising. Users often report Sachs as feeling closer to the stock ride of their vehicle, making them a good choice for those who prefer a smoother experience over sporty handling.
- Performance and Handling:
- Bilstein: Offers better control and stability, particularly in high-speed cornering or heavy-duty applications (e.g., towing or off-roading). The B6 and B8 series are designed for performance enthusiasts or lowered vehicles, providing tighter damping and improved responsiveness. Bilstein’s monotube design in some models enhances heat dissipation and durability under stress.
- Sachs: While reliable, Sachs shocks are less focused on performance and more on maintaining stock handling characteristics. They are less likely to enhance sporty driving but are sufficient for most standard driving conditions. Some users report Sachs as feeling “spongy” compared to Bilstein in performance scenarios.
- Durability and Longevity:
- Bilstein: Widely praised for longevity, with users reporting 100,000+ miles on some models (e.g., B4, B6). The monotube construction in higher-end models contributes to their durability, especially in demanding conditions.
- Sachs: Also durable, often lasting as long as OEM shocks (e.g., 172,000 km on a Mercedes SLK). However, some users note that cheaper Sachs models may wear out faster than Bilstein, particularly in harsh conditions.
- Price:
- Bilstein: Often slightly cheaper for equivalent models (e.g., Bilstein B4 vs. Sachs OEM). For example, Bilstein B4s can be found for $330–$450 per set, while Sachs OEM equivalents may cost $400 or more. However, Bilstein’s performance lines (B6, B8) are pricier.
- Sachs: Can be more expensive in some cases, but prices vary by retailer and region. For instance, Sachs were reported as twice the price of Bilstein B4s in one case, though occasionally cheaper through specific suppliers like AutoDoc.
- Availability:
- Bilstein: Some users report supply issues, particularly for B4 models, which can be hard to source from certain suppliers.
- Sachs: Generally more available as an OEM replacement, especially for European vehicles.
- Application:
- Bilstein: Offers a range of options:
- B4 (Touring Class): OEM replacement, similar to stock ride but with slightly better control.
- B6 (Heavy Duty): Firmer, for performance or heavy-duty use.
- B8 (Sport): Designed for lowered vehicles or aggressive driving, very firm.
- Suitable for those who want improved handling or a sportier feel.
- Sachs: Typically OEM or close-to-OEM replacements, ideal for maintaining factory ride quality. Sachs Sport models are firmer but still softer than Bilstein B6/B8.
User Feedback and Experiences
- Bilstein:
- Users appreciate Bilstein B4s for their balance of firmness and comfort after a break-in period (about a week), though some find them too stiff for pothole-heavy roads.
- B6 and B8 models are praised for handling improvements but criticized for harshness in daily driving, especially in urban environments with poor roads.
- Some report Bilsteins lasting longer than Sachs, with fewer replacements needed.
- Sachs:
- Preferred by those prioritizing comfort, especially for non-sport suspensions. Users replacing worn Sachs with new Sachs report satisfaction with ride quality.
- Some users find Sachs Sport shocks firmer than expected, occasionally harsher than adjustable alternatives like Koni Yellows.
- Sachs are often chosen for their OEM pedigree, ensuring a factory-like experience.
Recommendations
- Choose Bilstein if:
- You prioritize handling and stability, especially for spirited driving, towing, or performance upgrades (e.g., lowered springs or sway bars).
- You’re okay with a firmer ride and potentially better longevity.
- Your vehicle has a sport suspension, and you want to maintain or enhance its performance (B6 or B8 recommended).
- Example: Bilstein B4 for OEM-like ride with slight firmness, B6/B8 for performance.
- Choose Sachs if:
- Comfort is your top priority, and you want a ride close to the factory feel.
- You drive primarily on rough roads or value a softer, more compliant suspension.
- Your vehicle uses Sachs as OEM, and you want to maintain stock characteristics.
- Example: Sachs OEM or Sport for a balanced, comfortable ride.
- Additional Considerations:
- Springs and Mounts: Replace associated components (e.g., strut mounts, bump stops, springs) for optimal performance and to avoid issues like clunking or premature wear. Lemfoerder mounts are often recommended as OEM-quality.
- Vehicle-Specific Fitment: Ensure compatibility with your vehicle’s suspension (e.g., sport vs. non-sport, lowered vs. stock height). Bilstein B8s are specifically for lowered vehicles, while B4s and Sachs are better for stock setups.
- Road Conditions: If you frequently encounter potholes or rough roads, Sachs or Bilstein B4s are likely better choices than the firmer B6/B8.
Conclusion
Both Bilstein and Sachs are high-quality brands with strong reputations. Sachs is the go-to for a comfortable, OEM-like ride, ideal for daily drivers who prioritize smoothness. Bilstein shines for those seeking improved handling and a sportier feel, with the B4 being a good middle ground and B6/B8 catering to performance enthusiasts. Consider your driving style, road conditions, and whether you’re keeping stock springs or upgrading to performance springs when making your choice.
