V420117 Buffer

V420117 Buffer – Precision Suspension Solution

The V420117 Buffer is a high‑performance suspension shock absorber designed for front axle applications in passenger cars, particularly the Peugeot 407 series. Manufactured in Germany by VAICO, this component delivers reliable damping, enhanced ride comfort, and superior handling characteristics.

Key Features & Technical Highlights

• Material Excellence: Constructed from high‑strength steel and reinforced with a rubber elastomer lining, the buffer resists fatigue and corrosion, ensuring long service life.
• Optimized Damping Curve: Engineered to provide a smooth transition between soft initial compression for everyday driving and stiffening under heavy load, maintaining vehicle stability during cornering or sudden braking.
• Compact Design: The compact geometry allows seamless integration into existing chassis without requiring extensive modifications, making it a drop‑in replacement for older models.
• Temperature Resilience: Capable of operating effectively across a wide temperature range (–40 °C to +120 °C), the buffer maintains consistent performance in both cold and hot climates.
• Low Maintenance: The sealed construction eliminates the need for regular oil changes or fluid checks, reducing maintenance overhead for owners and fleet operators alike.

Compatibility & Application Scope

The V420117 Buffer is specifically tailored for the front axle (Vanguard) of Peugeot 407 models, including:

• Peugeot 407 Sedan (Berline)
• Peugeot 407 Station Wagon (SW)
• Peugeot 407 Coupe

Its design aligns with the original suspension geometry, ensuring that steering feel and braking dynamics remain unchanged while improving ride quality.

Installation Overview

1. Preparation: Remove the existing front shock absorber. Inspect mounting points for wear or damage; replace any compromised components before installation.
2. Mounting: Align the V420117 Buffer with the factory mounting brackets. Secure using the supplied bolts and torque specifications to guarantee a firm fit.
3. Alignment Check: Verify that the buffer sits flush against the chassis and that no play exists between the shock body and mounting hardware.
4. Functional Test: Perform a short drive test, checking for any abnormal noises or vibrations. Confirm that the suspension behaves as expected under load.

Performance Benefits

• Enhanced Comfort: The buffer’s progressive damping reduces road‑induced oscillations, delivering a smoother ride over uneven surfaces.
• Improved Handling: By maintaining optimal tire contact with the road, the V420117 Buffer contributes to tighter steering response and better cornering stability.
• Durability: The robust construction resists wear from repeated compression cycles, extending the lifespan of the suspension system.

Manufacturing & Quality Assurance

Produced in a dedicated German facility, each V420117 Buffer undergoes rigorous testing procedures, including:

• Static load tests to confirm structural integrity.
• Dynamic vibration analysis to ensure smooth operation under real‑world conditions.
• Environmental exposure trials to validate performance across temperature extremes.

These quality checks guarantee that every unit meets the stringent standards expected of premium automotive components.

Conclusion

The V420117 Buffer represents a blend of engineering precision and practical reliability. Its thoughtful design, proven performance in the Peugeot 407 lineup, and German manufacturing pedigree make it an ideal choice for drivers seeking to upgrade their vehicle’s suspension without compromising on quality or safety.
