Bilstein 19 – 246475 Shock Absorber

Bilstein 19‑246475 Shock Absorber Overview

The Bilstein 19‑246475 is a high‑performance B4 gas‑charged shock absorber designed to replace the original equipment (OE) units on a range of compact vehicles, including the Toyota Aygo, Peugeot 108, and Citroën C1 II. This component delivers superior damping characteristics, improved ride comfort, and enhanced handling stability across a variety of driving conditions.

Key Design Features

• B4 Gas Technology: The shock absorber incorporates a sealed gas chamber that pre‑pressurizes the oil, reducing cavitation and maintaining consistent damping throughout the travel range.
• Durable Construction: Made from high‑strength steel with reinforced bushings, the unit resists fatigue and corrosion, ensuring long service life even under aggressive driving.
• Compact Profile: The design fits within the original mounting envelope, allowing direct replacement without modification to suspension geometry or wheel alignment.
• Consistent Performance: The damping curve is engineered for a smooth transition from low‑speed bumps to high‑speed cornering, providing predictable handling and reduced body roll.

Compatibility and Vehicle Applications

The 19‑246475 is specifically calibrated for the rear suspension of:

• Toyota Aygo (2014–present)
• Peugeot 108 (2014–present)
• Citroën C1 II (2014–present)

These models share a common rear suspension architecture, enabling the shock absorber to be used interchangeably across all three brands without compromising fitment or performance.

Installation Guide

1. Safety First: Raise the vehicle using a jack and secure it on jack stands. Remove the rear wheels to access the suspension components.
2. Remove Old Shock: Disconnect the upper mounting bolt, then detach the lower mounting point by loosening the retaining nut. Carefully slide the old shock absorber out of its housing.
3. Prepare New Unit: Inspect the new 19‑246475 for any shipping damage. Verify that the mounting bolts and bushings match OEM specifications.
4. Install Shock: Position the new unit in place, aligning it with the upper and lower mounting points. Tighten the retaining nut to the manufacturer’s torque specification (typically 30–35 Nm).
5. Reassemble Wheels: Reinstall the rear wheels and lower the vehicle. Perform a wheel alignment if required.
6. Test Drive: Conduct a short test drive, checking for any unusual noises or handling issues. Adjust suspension settings if necessary.

Performance Benefits

• Improved Ride Comfort: The gas‑charged design smooths out road irregularities, reducing vibration transmitted to the cabin.
• Enhanced Handling Stability: Consistent damping reduces body roll during cornering, giving drivers greater confidence on winding roads.
• Long-Term Durability: High-quality materials and sealed construction protect against oil leakage and wear, extending service intervals.
• Reduced Maintenance Costs: By replacing the original shock absorber with a proven aftermarket unit, owners can avoid costly OEM replacements while maintaining vehicle performance.

Tuning Options for Enthusiasts

While the stock 19‑246475 is engineered for everyday driving, enthusiasts may consider:

• Adjustable Dampers: Swapping to a fully adjustable shock absorber allows fine-tuning of compression and rebound settings.
• Performance Bushings: Upgrading the suspension bushings can further enhance handling precision.
• Weight Reduction: Lightweight aftermarket components reduce unsprung mass, improving acceleration and braking response.

Maintenance Tips

• Regular Inspection: Check for oil leaks around the mounting points every 10,000 km. A small leak can indicate a worn seal.
• Re-torque Fasteners: After the first few hundred kilometers, re‑torque the mounting bolts to ensure secure attachment.
• Clean Surrounding Area: Keep the shock absorber and its housing free from debris and road salt to prevent corrosion.
• Replace When Needed: If you notice a noticeable change in ride quality or handling, consider replacing the unit sooner rather than later.
