1996–2002 Toyota 4Runner Rear Shock Absorber

Part #: 25-311310

Overview

The Bilstein 5160 Series rear shock absorbers are engineered to deliver exceptional performance and durability for your Toyota 4Runner, especially when equipped with a lift or off-road modifications. Designed as a direct fit replacement, these shocks are ideal for enthusiasts seeking improved ride quality, enhanced wheel travel, and increased cooling capacity during demanding driving conditions. Whether you're tackling rugged trails or enjoying daily driving, the Bilstein 5160 shocks help support your vehicle's performance and reliability.

Built with a remote reservoir design, these shocks provide superior heat dissipation, reducing fade and maintaining consistent damping performance over extended use. The monotube construction ensures a smooth, controlled ride while offering precise handling and stability. With velocity-sensitive digressive valve settings, each shock is tuned specifically for the Toyota 4Runner application, optimizing performance across a variety of terrains and driving styles.

Key Features

The Bilstein 5160 Series shocks incorporate advanced engineering and high-quality materials to enhance your vehicle's capabilities. Key features include:

• Remote reservoir design with a high-capacity nitrogen chamber for increased cooling and consistent damping performance during extended off-road or spirited driving.
• Monotube construction that provides a more responsive and fade-free ride compared to traditional twin-tube shocks.
• Velocity-sensitive digressive valves that adapt to changing road conditions, delivering a smooth ride and improved handling.
• Heavy-duty mounting hardware and durable components designed to withstand harsh off-road environments and demanding driving conditions.
• Custom-tuned for lifted Toyota 4Runners, ensuring optimal wheel travel and ride quality when used with suspension lifts or off-road setups.
• Corrosion-resistant finishes to ensure longevity and reliable performance in challenging weather and terrain.

Construction & Design

The Bilstein 5160 shocks feature a robust monotube design constructed from high-strength steel and corrosion-resistant finishes, ensuring durability and longevity. The remote reservoir is connected via high-pressure hoses, allowing for increased oil and nitrogen capacity, which helps dissipate heat more effectively during intense driving. The shock body and piston components are precision-machined for a perfect fit and smooth operation, while the internal valves are engineered to provide consistent damping across a wide range of conditions. This thoughtful design results in a shock absorber that not only improves ride comfort but also enhances off-road capability and stability.

Installation & Fitment

The Bilstein 5160 Series shocks are designed as direct bolt-on replacements for the factory rear shocks on 1996–2002 Toyota 4Runners. Installation is straightforward, requiring no modifications, cutting, or drilling. The shocks utilize the original mounting points and hardware, ensuring a secure and precise fit. Basic hand tools and some mechanical knowledge are recommended for installation. No tuning or additional adjustments are typically necessary, allowing you to quickly upgrade your vehicle's suspension for improved performance and ride quality.
