Whiteline Suspension Trailing Arm Bushing

2006–2013 Lexus IS250 / IS350

Part #: W63586

Overview

The Whiteline Suspension Trailing Arm Bushing is a high-performance upgrade designed to enhance the handling and stability of your Lexus IS250 or IS350 from 2006 to 2013. These bushings are engineered to optimize rear suspension geometry, providing a more precise and predictable driving experience. Whether you're a spirited driver, a track enthusiast, or simply looking to improve your vehicle's road manners, these bushings deliver noticeable improvements in handling dynamics.

Over time, factory trailing arm bushings can wear out or become soft, leading to excessive rear suspension movement, misalignment, and reduced steering response. Whiteline's trailing arm bushings address these issues by controlling unwanted movement, helping to restore factory-like alignment accuracy and ensuring your vehicle responds confidently to driver inputs. This upgrade is especially beneficial for those seeking improved cornering stability, reduced body roll, and enhanced driver reassurance during spirited driving or challenging road conditions.

Key Features

Whiteline's trailing arm bushings are crafted with precision and durability in mind, offering a significant upgrade over stock components. The key features include:

• High-quality polyurethane material that provides superior durability and resistance to wear compared to OEM rubber bushings.
• Designed to control excessive rear suspension movement, improving dynamic alignment and handling consistency.
• Precisely engineered to restore or improve factory suspension geometry, enhancing steering response and stability.
• Resistant to harsh environmental conditions, including heat, oil, and road debris, ensuring long-lasting performance.
• Easy to install with a direct bolt-on design, requiring no additional modifications or specialized tools.
• Reduces unwanted suspension flex, leading to more predictable handling during aggressive driving or cornering.
• Contributes to a more confident and connected driving experience, especially on twisty roads or track days.

Construction & Design

Whiteline's trailing arm bushings are constructed from high-grade polyurethane, which strikes an optimal balance between firm handling and ride comfort. The bushings are precisely molded to fit the OEM mounting points, ensuring a perfect fit and seamless installation. Their one-piece design eliminates the need for complex assembly and reduces the risk of squeaks or vibrations often associated with inferior aftermarket bushings. The durable materials and robust construction ensure these bushings maintain their shape and performance over the lifespan of your vehicle, even under demanding driving conditions.

Performance & Handling

By replacing worn or degraded factory bushings with Whiteline's high-performance trailing arm bushings, you'll experience improved rear suspension response and more accurate alignment. This translates to better steering feel, reduced understeer or oversteer tendencies, and enhanced overall stability. While these bushings do not directly increase horsepower, they support your vehicle's handling capabilities, making every drive more engaging and confident. The improved control and reduced suspension flex help you maintain optimal tire contact with the road, especially during aggressive cornering or quick maneuvers.

Installation & Fitment

The Whiteline Suspension Trailing Arm Bushings are designed for a straightforward, bolt-on installation. Typically, no cutting, drilling, or complex modifications are required. Basic hand tools and some mechanical knowledge are sufficient to complete the upgrade. It is recommended to support the vehicle securely on jack stands and follow proper safety procedures during installation. For best results, consider aligning your vehicle after installation to maximize handling benefits and ensure proper suspension geometry.
