Installation Overview

Installing the BILSTEIN 19-172903 Shock Absorber is straightforward for experienced mechanics or knowledgeable DIY enthusiasts. The process typically involves:

1. Preparation: Secure the vehicle on a lift or jack stands, and remove the wheel to access the suspension.
2. Removal of Old Shock: Detach the existing shock absorber by loosening the upper and lower mounting bolts. Carefully disconnect any hydraulic lines if present.
3. Mounting the New Unit: Position the new shock absorber, aligning it with the mounting points. Tighten the bolts to the manufacturer’s specified torque settings.
4. Reassembly: Reinstall the wheel and lower the vehicle. Perform a test drive to confirm proper operation and check for any leaks or abnormal noises.

Compatibility Highlights

The 19-172903 model is specifically engineered for use on front suspension assemblies of Nissan vehicles, notably:

• Nissan NP300 Navara (D40) – models from 2005 onward.
• Other Nissan platforms that share the same mounting geometry and spring rates.

Its dual‑spring design allows it to be used on both front and rear suspension setups when required, providing a consistent feel across the vehicle’s entire suspension system.
