Sachs 900 238 - Rubber Buffer, suspension

Sachs 900 238 Rubber Buffer – Suspension

The Sachs 900 238 is a high‑performance rubber buffer designed for the rear suspension of Nissan Qashqai, Renault Kadjar and similar models. It serves as a bump stop, absorbing impact when the wheel reaches the end of its travel and protecting the shock absorber from damage.

Key Functionalities

• Bump Stop Action: When the suspension compresses fully, the rubber buffer engages to cushion the final contact, preventing hard impacts on the strut assembly.
• Durable Construction: Made from premium elastomeric material that resists abrasion, temperature extremes and chemical exposure typical of automotive environments.
• Low Maintenance: Requires no lubrication or periodic adjustment; it maintains its shape and performance over thousands of miles.

Compatibility and Fitment

The buffer is engineered to fit the rear axle of:

• Nissan Qashqai (including the +2 I variant)
• Renault Kadjar (HA, HL models)
• X‑Trail and other Nissan SUVs with similar suspension geometry

It is supplied as a pair to ensure symmetrical performance on both sides of the vehicle.

Installation Overview

1. Remove the existing rubber buffer or damaged component from the rear strut assembly.
2. Clean the mounting surface to remove debris and old sealant.
3. Position the new Sachs 900 238 onto the strut, aligning it with the designated groove.
4. Secure any retaining clips or fasteners as per manufacturer guidelines.
5. Verify that the buffer sits flush and does not interfere with wheel travel.

Performance Benefits

• Enhanced Ride Comfort: By absorbing the final impact, the buffer reduces harshness felt by occupants during off‑road or uneven surface driving.
• Extended Component Life: Protects shock absorbers and strut housings from sudden loads that could cause premature wear or failure.
• Consistent Handling: Maintains predictable suspension behavior, especially during aggressive cornering or rapid acceleration.

Material Characteristics

The elastomer used in the Sachs 900 238 is formulated with a blend of natural and synthetic rubbers, reinforced with carbon black for strength. This composition offers:

• High tensile strength to withstand repeated compression cycles.
• Excellent resilience at temperatures ranging from –40 °C to +120 °C.
• Resistance to oil, fuel and brake fluid exposure.

Maintenance Tips

• Inspect the buffer annually for signs of cracking or hardening; replace if any deformation is observed.
• Avoid exposing the buffer to prolonged direct sunlight without shade, as UV radiation can accelerate aging.
• Keep the surrounding area clean to prevent debris from embedding into the rubber surface.
