Key Features

The Eibach ERS features advanced engineering designed to deliver optimal performance and durability. Key features include:

• High-strength steel construction with a durable finish to resist corrosion and wear over time.
• External reservoir design allows for increased oil capacity, which helps dissipate heat more effectively during extended use or aggressive driving.
• Adjustable damping settings enable fine-tuning of ride comfort and handling characteristics to match your driving style and conditions.
• Precision-machined components and TIG-welded construction ensure a secure, leak-free seal and long-lasting performance.
• Designed to support aggressive driving, off-road use, or high-performance street applications.
• Load capacity of 400 lbs/inch and a load at block height of approximately 4,248 lbs, providing excellent support for heavy-duty use.
• Weight of approximately 14.96 lbs (6.8 kg), making it a robust yet manageable upgrade for your suspension system.

Construction & Design

The Eibach ERS shock absorber is built with a focus on durability and performance. Its main body is constructed from high-quality steel, ensuring strength and resistance to bending or deformation under load. The external reservoir is connected via a high-pressure hose, allowing for increased oil volume and better heat dissipation, which reduces fade during prolonged or aggressive driving sessions.

The shock features a precise piston and valving system that provides a smooth, controlled ride while maintaining excellent handling characteristics. The adjustable damping mechanism allows you to tailor the shock's response to your specific needs, whether for comfort, performance, or off-road capability. The overall design emphasizes reliability, with TIG welding and meticulous manufacturing processes to ensure longevity and consistent performance over time.

Installation & Fitment

The Eibach ERS shocks are designed for straightforward installation with bolt-on compatibility. They typically utilize existing mounting points and require no cutting or drilling. However, due to their universal design, some minor adjustments or custom fittings may be necessary depending on your specific vehicle application. It is recommended to consult your vehicle's service manual or a professional installer for optimal results.

No special tuning or modifications are generally required, but adjusting the damping settings can help you achieve the desired ride characteristics.

• Easy bolt-on installation with standard tools
• No cutting, drilling, or complex modifications needed in most applications
