Sachs 900 379 Wheel Suspensions

Sachs 900 379 Wheel Suspension Kit

The Sachs 900 379 is a comprehensive wheel suspension service kit designed to restore optimal performance and longevity to the rear suspension of selected vehicles, most notably the Audi A3 Sportback. This kit combines precision engineering with high‑grade materials to provide reliable protection against dust, debris, and environmental contaminants while ensuring smooth shock absorber operation.

Key Components

• Dust Cover (Staubschutzsatz): A robust, weather‑resistant cover that seals the rear suspension assembly, preventing ingress of dust, water, and road grime. Constructed from durable polymer with reinforced stitching for extended life.
• Shock Absorber Service Kit: Includes a new shock absorber seal, mounting brackets, and all necessary fasteners to replace worn or damaged parts without compromising the suspension geometry.
• Spring Travel Limiter (Federwegbegrenzer): A precision‑cut limiter that restricts excessive spring travel, protecting the suspension from overextension during hard braking or aggressive cornering.
• Dust Seal (Staubmanschette): An additional seal positioned around the shock absorber mounting point to further reduce dust penetration and maintain internal fluid integrity.

Technical Specifications

Benefits of the Sachs 900 379 Kit

• Enhanced Durability: By sealing the suspension assembly, the kit protects critical components from moisture and particulate matter that can accelerate wear.
• Improved Ride Quality: The spring travel limiter ensures consistent damping characteristics, reducing harshness during sudden stops or uneven road surfaces.
• Easy Maintenance: All parts are pre‑assembled with clear labeling, allowing technicians to perform replacements quickly and accurately.
• Consistent Performance: The high‑quality shock absorber seal maintains fluid integrity, preventing leaks that could compromise braking performance or vehicle handling.
• Long‑Term Cost Savings: Preventing premature wear reduces the need for frequent suspension repairs and extends the service life of the vehicle’s rear axle components.

Installation Overview

1. Preparation: Secure the vehicle on a lift or jack stands. Remove any existing dust covers or seals that may interfere with installation.
2. Shock Absorber Replacement: Detach the old shock absorber using the specified torque settings. Install the new shock absorber, ensuring the seal is seated correctly and all mounting bolts are tightened to spec.
3. Spring Travel Limiter Installation: Position the limiter on the spring assembly, aligning it with the designated notch. Fasten according to the manufacturer’s instructions.
4. Dust Cover Application: Place the dust cover over the rear suspension housing, securing it with the provided fasteners. Verify that the cover fits snugly and does not interfere with any moving parts.
5. Final Checks: Inspect all connections for proper torque, confirm no gaps in sealing, and perform a test drive to ensure smooth operation.

Maintenance Tips

• Inspect the dust cover annually for cracks or wear; replace if compromised.
• Check shock absorber seals every 20,000 km (or as recommended by the vehicle manufacturer) and replace if signs of leakage appear.
• Verify spring travel limiter alignment after any suspension work to maintain correct geometry.
