Description

The Whiteline 24-25 Lexus GX550 Trailing Arm Upper is a heavy-duty, adjustable trailing arm designed to enhance suspension performance. Constructed with durable materials, this turnbuckle-style component allows for precise, incremental adjustment of the differential pinion angle directly on the vehicle. By enabling fine-tuning of the rear suspension geometry, it helps improve traction and stability under heavy acceleration conditions. The design ensures robust performance and longevity, making it suitable for demanding driving scenarios. When paired with Whiteline's heavy-duty upper trailing arms, it offers an optimized upgrade for enhanced handling and durability. This product is specifically engineered for the 2024 and 2025 Lexus GX550 models. It is intended as a direct replacement and upgrade for the factory upper trailing arms, providing adjustable features for improved traction and suspension tuning. Ideal for off-road, towing, or performance-oriented driving, this component is designed for easy bolt-on installation. The kit includes the adjustable trailing arm assembly, allowing users to customize their vehicle’s differential pinion angle for better control and handling across various driving conditions.
