SACHS 317 255 Shock Absorber For Mercedes-Benz 190

SACHS 317 255 Shock Absorber for Mercedes-Benz 190

The SACHS 317 255 shock absorber is a high‑performance suspension component specifically engineered for the classic Mercedes-Benz 190 (W201), produced between 1982 and 1993. Designed to replace worn or damaged rear dampers, this unit delivers superior ride quality, handling stability, and durability under everyday driving conditions.

Key Features

• Gas‑Pressurized Design: The shock absorber incorporates a sealed gas chamber that maintains consistent damping force throughout the travel range, preventing sagging and ensuring predictable performance.
• Single‑Rod Construction: A robust single‑rod architecture provides excellent structural integrity while keeping weight low, which is critical for maintaining the vehicle’s original balance.
• High‑Quality Materials: Constructed from hardened steel and reinforced rubber seals, the unit resists corrosion and wear, extending service life even in harsh climates.
• Precision Tuning: The damping characteristics are calibrated to match the original suspension geometry of the Mercedes-Benz 190, preserving the car’s handling dynamics while improving comfort.
• Easy Installation: Designed with standard mounting points and bolt patterns, the shock absorber can be swapped in without extensive modifications or custom fabrication.

Compatibility Overview

The SACHS 317 255 is engineered for the rear axle of the Mercedes-Benz 190 series. It fits the following models and chassis codes:

• Mercedes-Benz 190 (W201) – 1982 to 1993 production years.
• Rear suspension assemblies with standard A1243261200, A1243262300, or equivalent bolt patterns.
• Vehicles equipped with the original single‑rod rear shock absorber architecture.

Because of its standardized mounting geometry, the unit is also compatible with other vehicles that share the same rear suspension layout, such as certain SACHS 317 255 variants used in European markets. However, always verify bolt patterns and clearance before installation.

Installation Guide

1. Preparation: Raise the vehicle securely on jack stands, ensuring the rear wheels are free from ground contact. Remove the wheel to access the suspension components.
2. Remove Old Shock Absorber: Detach the upper and lower mounting bolts using a socket set. Carefully slide the old shock absorber out of its housing, noting any alignment marks or spacers that may be present.
3. Inspect Mounting Points: Check the mounting brackets for corrosion or damage. Clean all surfaces with a degreaser to ensure proper seal contact.
4. Install New Shock Absorber: Position the SACHS 317 255 into place, aligning it with the upper and lower mounts. Hand‑tighten the bolts first, then use a torque wrench to achieve the manufacturer’s specified torque (typically around 80–100 Nm).
5. Reassemble Wheel: Reinstall the wheel and lower the vehicle onto the ground. Perform a final torque check on all suspension fasteners.

For optimal performance, it is recommended to replace both left and right rear shock absorbers simultaneously, ensuring symmetrical handling characteristics.

Performance Benefits

• Improved Ride Comfort: The gas‑pressurized damping reduces road chatter and body roll, allowing drivers to enjoy a smoother ride over uneven surfaces.
• Enhanced Handling Stability: By maintaining consistent suspension travel, the shock absorber helps keep tires in optimal contact with the road during cornering and braking.
• Long‑Term Durability: The high‑grade materials and sealed construction protect against moisture ingress and mechanical fatigue, reducing maintenance frequency.
• Preservation of Original Dynamics: Because the unit is engineered to match the original suspension geometry, it preserves the classic feel of the Mercedes-Benz 190 while upgrading reliability.

Maintenance Tips

Although the SACHS 317 255 shock absorber is designed for longevity, periodic checks can help detect early signs of wear:

• Inspect rubber seals for cracks or hardening; replace if compromised.
• Check mounting bolts for tightness every 10,000 km (or as recommended by the vehicle’s service schedule).
• Listen for unusual noises such as clunking or popping during acceleration or braking; these may indicate internal wear.
• Ensure that the gas chamber remains sealed; any loss of pressure can lead to reduced damping performance.
