Whiteline Hydraulic Lock Kit

1989–1998 Nissan 240SX SE

Part #: KSR204

Overview

The Whiteline Hydraulic Lock Kit KSR204 is a specialized performance upgrade designed specifically for the Nissan 240SX SE models manufactured between 1989 and 1998. This kit is engineered to disable the factory-installed Hydraulic HICAS (High Capacity Actively Controlled Suspension) rear-steer system, a feature that can sometimes compromise handling precision during spirited driving or track use. By eliminating the hydraulic rear steering, you’ll experience more direct and predictable handling characteristics, especially at the vehicle's handling limits.

Ideal for enthusiasts who seek improved stability and control on the street or the track, the Whiteline Hydraulic Lock Kit transforms your Nissan 240SX into a more responsive and confident machine. Whether you're a dedicated track day driver or a street performance enthusiast, this kit helps you unlock the full potential of your vehicle’s chassis by removing the complexities and potential issues associated with the factory rear-steer system.

• Designed with a simple bolt-on installation process, requiring no cutting or extensive modifications to your vehicle’s chassis.
• Helps improve vehicle stability by eliminating rear-wheel toe changes caused by hydraulic system operation, resulting in more predictable handling at the limit.
• Reduces the complexity of rear suspension components, potentially decreasing maintenance needs and increasing reliability.
• Compatible with factory suspension and drivetrain components, ensuring a seamless upgrade without sacrificing ride quality.
• Designed specifically for Nissan 240SX SE models from 1989 to 1998, ensuring a perfect fit and function.

Construction & Design

The Whiteline Hydraulic Lock Kit features a robust design utilizing high-strength steel and corrosion-resistant finishes to withstand the rigors of performance driving. The kit includes precision-machined components that replace or block the hydraulic lines and actuators responsible for rear steering. Its straightforward design ensures that once installed, the system remains reliable and maintenance-free, providing a permanent solution to the HICAS system’s limitations.

The kit’s components are engineered to integrate seamlessly with the existing suspension setup, maintaining the vehicle’s original geometry and ride characteristics. The design also minimizes any additional weight or complexity, preserving the vehicle’s balance and handling dynamics.

Performance & Handling

Disabling the Hydraulic HICAS system with the Whiteline Lock Kit results in a more direct and predictable rear-end response. Drivers will notice improved steering feel and stability, especially during high-speed cornering or aggressive maneuvers. By removing the hydraulic system’s influence, the vehicle’s chassis becomes more responsive, allowing for quicker turn-in and more confident handling at the limit. This upgrade is particularly beneficial for track enthusiasts and those seeking a more engaging driving experience.

Installation & Fitment

The Whiteline Hydraulic Lock Kit is designed for a straightforward bolt-on installation, making it accessible for most DIY enthusiasts with basic mechanical skills. The process typically involves removing the hydraulic lines and actuators from the rear suspension and installing the provided lockout components in their place. No cutting, drilling, or complex modifications are required, and all necessary hardware is included.

While installation is relatively simple, it is recommended to follow the detailed instructions provided to ensure proper fitment and function. Once installed, the system is fully functional and requires no additional tuning or adjustments.
