Sachs 900 327 Wheel Suspensions

Overview

The Sachs 900 327 Wheel Suspension Kit is a high‑performance component designed to enhance the durability and reliability of rear suspension systems on a wide range of Volkswagen, Audi, and other OEM vehicles. This kit focuses on protecting critical shock absorber elements from dust, moisture, and mechanical wear, thereby extending service life and maintaining optimal ride quality.

Compatibility

The 900 327 series is engineered for the rear axle assemblies found in models such as the Volkswagen Touareg (7LA, 7L6, 7L7) from 2002‑2013, Audi Q7 (4LB) 2006‑2016, and other vehicles that share the same suspension architecture. It fits both front‑wheel drive and all‑wheel drive configurations where the standard Sachs shock absorber is employed.

Design Features

• Dust & Moisture Seal: The kit incorporates a robust dust cover that seals the upper portion of the shock absorber, preventing ingress of dirt and water.
• Protective Capuchon: A reinforced cap covers the top of the shock, shielding it from impact damage during off‑road or heavy‑load conditions.
• Folding Baggage (Faltenbalg): The flexible rubber sleeve accommodates suspension travel while maintaining a tight seal against contaminants.
• Integrated Spring Travel Limiter: A small but effective component limits excessive spring extension, reducing the risk of bottom‑out damage.

Materials & Construction

The kit is fabricated from high‑grade steel and reinforced rubber composites. The steel components are treated with anti‑corrosion coatings to resist rust in harsh environments, while the rubber elements are engineered for long‑term elasticity and resistance to oil and fuel exposure.

Installation Process

1. Remove Existing Shock Assembly: Detach the current shock absorber from the rear axle, ensuring all mounting bolts are properly loosened.
2. Attach Dust Cover: Slide the dust cover onto the upper portion of the new shock, aligning it with the mounting flange.
3. Secure Protective Cap: Place the cap over the dust cover and fasten it using the supplied screws or clips.
4. Install Folding Sleeve: Fit the rubber sleeve around the shock body, ensuring a snug fit without gaps.
5. Mount Shock to Axle: Reattach the shock absorber to the axle housing, tightening all bolts to manufacturer specifications.
6. Verify Alignment: Check that the dust cover and cap remain in place during suspension movement before final torque application.

Maintenance Guidelines

Regular inspection of the dust cover and protective cap is recommended. Look for signs of wear, cracking, or oil leakage. Replace any compromised components immediately to preserve seal integrity. Periodic cleaning of the rubber sleeve with mild detergent will prevent buildup that could impede flexibility.

Performance Benefits

• Extended Shock Life: By shielding critical parts from dust and moisture, the kit reduces wear on internal pistons and seals.
• Consistent Ride Quality: The integrated spring travel limiter maintains optimal suspension geometry, preventing harsh bottom‑out events.
• Improved Reliability in Harsh Conditions: Off‑road or high‑dust environments see fewer failures due to the robust protective design.
• Ease of Replacement: Standardized mounting points and straightforward installation make it a convenient upgrade for mechanics and DIY enthusiasts alike.
