Sachs 318143 Rear Gas Pressure Monotube Shock Absorber

The Sachs 318143 is a rear axle gas pressure shock absorber engineered to OE standards for Audi A4 and A5 platforms. Built in monotube telescopic design with a top pin and bottom eye mounting configuration, this damper delivers precise, fade-free suspension control as a direct OEM-quality replacement.

The monotube construction pressurizes the working cylinder with oil and high-pressure gas, separated by a floating piston that ensures a completely leak-proof barrier. This design allows the unit to be installed in any orientation and eliminates the risk of hydraulic oil foaming or cavitation, maintaining consistent damping performance under all driving conditions.
