• Designed to reduce unwanted movement in the rear suspension, improving dynamic alignment and handling precision.
• Neutral (black) appearance, favored by restorers and racers for its classic look and compatibility with various vehicle finishes.
• Supplied with high-pressure molybdenum disulphide grease to ensure smooth operation and ease of installation.
• Engineered for live rear axle vehicles, providing enhanced chassis control and better transfer of power to the wheels.
• Durable construction that withstands the rigors of spirited driving, off-road adventures, and daily use.
• Designed to restore or improve upon factory suspension performance, making it suitable for both restoration projects and performance upgrades.

Construction & Design

The Whiteline Trailing Arm Lower Bushing is crafted from high-quality synthetic elastomer, which offers excellent resilience and flexibility. The bushing's design incorporates a robust metal sleeve to ensure proper fitment and secure mounting. The use of extreme pressure molybdenum disulphide (LM) based grease enhances lubrication, reduces friction, and prolongs service life. Its neutral black finish allows it to blend seamlessly with OEM components or custom builds, making it a versatile upgrade for a wide range of Nissan and Infiniti models.

The bushing's construction emphasizes durability and precise fitment, helping to eliminate unwanted suspension movement that can cause uneven tire wear, poor handling, and compromised safety. Its design also helps maintain proper suspension geometry during aggressive driving or heavy loads, supporting better control and driver confidence.

Performance & Benefits

Installing the Whiteline Trailing Arm Lower Bushing results in noticeable improvements in vehicle handling and chassis stability. By reducing excessive movement in the rear suspension, you'll experience more responsive steering, improved cornering grip, and a more planted feel during spirited driving. The upgraded bushing also helps support better driveline transfer, ensuring power delivered from the engine reaches the wheels efficiently.

While specific horsepower or torque gains are not claimed, the enhanced suspension control contributes to a more confident driving experience, especially on twisty roads or during track days. The durable elastomer material maintains its properties over time, providing consistent performance and peace of mind for daily drivers and performance enthusiasts alike.

Installation & Fitment

The Whiteline Trailing Arm Lower Bushing is designed as a direct replacement for the factory component, making installation straightforward for those with basic suspension knowledge. It uses the original mounting points and does not require any cutting or drilling. The process typically involves removing the rear suspension components, pressing out the old bushing, and pressing in the new Whiteline bushing with standard tools. No special tuning or alignment adjustments are necessary, but a professional alignment is recommended after installation to ensure optimal handling.

• Bolt-on installation with common hand tools and a press or bushing removal/installation tool.
• No cutting, drilling, or modifications required.
• Suitable for a wide range of Infiniti and Nissan models with live rear axles.
