Whiteline Steering Rack & Pinion Mount Bushing Kit

1990–1996 Nissan 300ZX

Part #: W13405

Overview

The Whiteline Steering Rack & Pinion Mount Bushing Kit is designed to enhance the steering performance and feedback of your Nissan 300ZX from 1990 to 1996. Modern driving conditions, including aggressive wheel alignment, wider wheels, and lower profile tires, place increased load on your vehicle’s steering components. Additionally, engine bay contaminants such as oil leaks can accelerate the degradation of factory bushings, leading to imprecise steering and increased play. This kit offers a durable solution to maintain optimal steering feel and responsiveness.

Whether you're a performance enthusiast, a daily driver seeking improved steering precision, or restoring your vehicle’s handling characteristics, the Whiteline bushings are engineered to withstand the rigors of spirited driving and harsh conditions. By replacing worn or degraded factory mounts, you'll experience more direct steering response, better feedback, and a more confident driving experience.

Key Features

The Whiteline Steering Rack & Pinion Mount Bushing Kit incorporates advanced materials and design features to improve your vehicle’s steering performance:

• Constructed from high-quality, durable polyurethane that resists oil, heat, and contaminants, ensuring long-lasting performance in demanding conditions.
• Engineered to reduce unwanted movement and play in the steering rack, resulting in more precise and predictable steering response.
• Designed to absorb vibrations and road shocks, enhancing overall ride comfort without sacrificing steering feel.
• Manufactured with exact fitment for the Nissan 300ZX, ensuring straightforward installation and a secure, OEM-like fit.
• Helps support improved alignment geometry by maintaining proper rack positioning, which can contribute to better tire wear and handling.
• Resistant to degradation from engine bay contaminants, oil leaks, and environmental factors, extending the lifespan of your steering components.
• Ideal for street driving, spirited canyon carving, or track days where precise steering feedback is essential.

Construction & Design

The Whiteline bushings are crafted from a proprietary polyurethane compound that balances firmness with flexibility, providing a noticeable improvement over the softer factory rubber mounts. The bushings are precision-machined to ensure perfect alignment with the factory mounting points, facilitating an easy installation process. Their one-piece design offers enhanced stability and durability, resisting cracking, splitting, or deformation over time.

The kit’s design focuses on maintaining the integrity of your vehicle’s steering geometry while damping unwanted vibrations. The high-quality materials and manufacturing processes, including TIG welding and CAD development, ensure a consistent, reliable fit and function. This attention to detail results in a product that not only improves steering response but also contributes to the overall longevity of your steering rack assembly.

Performance & Feedback

By replacing worn or degraded factory bushings with the Whiteline kit, you'll notice a more direct and responsive steering feel. The increased stiffness reduces play in the rack mount, translating to sharper turn-in and improved feedback from the road. While specific horsepower or torque gains are not applicable, the upgrade significantly enhances the handling precision and driver confidence, especially during aggressive driving or high-speed maneuvers.

Installation & Fitment

The Whiteline Steering Rack & Pinion Mount Bushing Kit is designed as a bolt-on upgrade that requires no cutting, drilling, or complex modifications. The installation involves removing the existing bushings and replacing them with the new polyurethane mounts, which fit directly into the factory mounting points. Basic hand tools and alignment adjustments are typically sufficient. For best results, a professional wheel alignment is recommended after installation to optimize handling and tire wear.
