Bilstein 24-113373 Shock Absorber

Bilstein 24-113373 Shock Absorber

The Bilstein 24-113373 is a high‑performance shock absorber engineered for the rear suspension of Mercedes‑Benz G‑Class and other heavy‑duty vehicles. Designed as an OEM replacement, it delivers superior damping characteristics, durability, and ride comfort in demanding off‑road and on‑road conditions.

Key Design Features

• Single‑Pipe Gas‑Pressurized Construction: The shock features a sealed single‑pipe design with nitrogen gas pre‑pressurization, reducing internal friction and extending service life.
• B4 Series Technology: Incorporates Bilstein’s B4 series damping technology, offering a smooth transition from hard to soft compression for improved handling and comfort.
• High‑Strength Steel Housing: The housing is fabricated from high‑strength steel with reinforced welds, ensuring resistance to impact and fatigue under heavy loads.
• Integrated Oil Seal System: A dual oil seal arrangement prevents leakage, maintaining optimal hydraulic pressure over extended periods.
• Compact Footprint: Designed to fit within the original mounting space of the G‑Class rear suspension without requiring additional modifications.

Performance Characteristics

The Bilstein 24-113373 delivers a balanced damping curve that adapts to varying road surfaces. Its performance can be summarized as follows:

Compatibility Overview

The shock absorber is specifically engineered for the following vehicle models:

• Mercedes‑Benz G‑Class (W460, W461) – Rear suspension
• Steyr Mercedes‑Benz – Various rear axle configurations
• Other OEM vehicles that use the B4 series rear shock architecture (consult Bilstein technical data for exact fitment).

It is available in both left and right side variants, ensuring symmetrical performance across the vehicle’s rear axle.

Installation Procedure

1. Preparation: Raise the vehicle securely on jack stands. Remove the existing shock absorber by loosening the mounting bolts with a torque wrench set to the manufacturer’s specifications.
2. Removal of Old Shock: Carefully detach the old unit, noting any alignment marks or retaining clips that may be present.
3. Mounting New Shock: Position the Bilstein 24-113373 in place. Align the mounting points precisely to avoid stress on the housing.
4. Tightening Sequence: Tighten bolts in a crisscross pattern, gradually increasing torque to the specified value (typically 70–80 Nm). Use a calibrated torque wrench for accuracy.
5. Fluid Check: Verify that the oil level is within the manufacturer’s recommended range. If necessary, top up with Bilstein’s high‑performance shock oil.
6. Final Inspection: Inspect all connections for leaks and ensure that the shock absorber moves freely without binding.

Maintenance Guidelines

While the Bilstein 24-113373 is designed for long life, regular checks can extend its service interval:

• Visual Inspection: Every 10,000 km or annually, inspect for oil leaks, corrosion, and physical damage.
• Oil Replacement: Replace the shock oil every 20,000–30,000 km to maintain damping performance.
• Torque Checks: Re‑torque mounting bolts after any suspension work or if a significant impact occurs.
• Alignment Verification: After installation, confirm that wheel alignment parameters remain within manufacturer tolerances.

Benefits for Drivers and Vehicle Owners

• Enhanced Ride Comfort: The B4 damping technology smooths out road irregularities, reducing driver fatigue on long journeys.
• Improved Handling: Firm compression support keeps the vehicle stable during aggressive maneuvers and off‑road excursions.
• Durability: High‑strength construction resists wear from heavy loads and rough terrain, minimizing replacement frequency.
• Consistent Performance: Gas pressurization maintains hydraulic pressure over time, ensuring predictable behavior across the shock’s lifespan.
