1. What Is an External Reservoir in Shock Absorbers?

Un external reservoir in a shock absorber is an additional chamber that holds hydraulique fluid and nitrogen gas separately from the main shock body. This design is commonly found in high-performance and off-road shock absorbers where thermal management and extended travel are critical. It is engineered to offer better performance d'amortissement, cooling efficiencyet longer shock life under extreme conditions.

Key Components of an External Reservoir Shock Absorber

Composant	Fonction
Main Shock Body	Houses the piston and primary damping fluid
Réservoir externe	Contains additional nitrogen gas and/or hydraulic oil
High-Pressure Hose or Tube	Connects the reservoir to the main shock body
Piston flottant	Separates the gas and oil in the reservoir to prevent cavitation
Compression Adjuster (optional)	Allows tuning of damping characteristics based on terrain or load

Benefits of External Reservoir Shock Absorbers in B2B Applications

• Dissipation de la chaleur : Increased fluid volume improves cooling, essential for racing and long-haul applications.
• Reduced Cavitation: The separation of nitrogen gas and oil prevents aeration, ensuring consistent damping.
• Extended Stroke: The remote reservoir allows more room in the main body for piston travel, ideal for high-travel suspension systems.
• Customization Flexibility: Allows for réglage de précision, making them ideal for OEM, specialty vehicle manufacturerset aftermarket performance brands.

For businesses in the automotive supply chain, understanding and offering these shock absorbers can lead to higher value product lines et better customer retention in the performance parts segment.

• More compact and self-contained
• Common in racing and performance applications

Inconvénients :

• Less flexibility in positioning
• May experience heat transfer from the main body

Réservoirs éloignés

Remote reservoirs are connected to the shock body via a high-pressure hose, allowing more freedom in placement. This is ideal for custom vehicle builds et applications needing better cooling.

Avantages :

• Better thermal management (reservoir can be mounted in cooler locations)
• Greater oil volume and stroke length
• Easier access to adjusters in confined chassis setups

Inconvénients :

• Installation plus complexe
• Requires additional space for hose routing

Fonctionnalité	Réservoir Piggyback	Réservoir à distance
Installation	Easier, compact	More complex, flexible
Efficacité du refroidissement	Modéré	Haut
Ajustement	Limited by position	Highly accessible
Application	Course automobile, voitures de performance	Off-road, 4×4, RVs
