Installation Notes and Tips
When installing the Bilstein 25-325805 shock absorber on a Toyota Tundra, ensure the vehicle is securely lifted and supported. Verify the upper stem and lower eye mount types match the vehicle’s mounting points. No spring seat or boot is included, so retain or replace these components as needed. Since the damping is non-adjustable, no tuning is required post-installation. It is recommended to replace shocks in pairs to maintain balanced suspension performance.
