Adjustable Rear Upper Trailing Arms

The Dobinsons Adjustable Rear Upper Trailing Arms (WA59-571K) are engineered to enhance rear suspension geometry, driveline alignment, and overall durability for vehicles, particularly those with suspension lifts. This pair of arms allows for precise adjustment of the rear axle's pinion angle, which is critical for maintaining proper driveline operation and stable handling after modifications. Constructed from High Strength Low Alloy (HSLA) steel with a robust wall thickness, these trailing arms provide exceptional strength and resistance to bending, ensuring long-term reliability. The adjustable design allows for fine-tuning of the pinion angle, a key benefit for lifted applications. To ensure longevity and resist environmental factors, the arms are finished with a protective zinc plating and a durable black powder coat. Installation is facilitated by their direct bolt-on replacement design, meaning no additional modifications are typically required. This product is recommended for vehicles with a 2-inch lift or more, helping to center the rear axle under the frame and fits on top of the factory coil seat isolator. The trailing arms are suitable for use on vehicles lifted up to 4 inches and are also compatible with long-travel suspension setups. These trailing arms are designed for a wide range of compatible Toyota and Lexus models, including the Toyota Tundra 3rd Gen (2022-2025), Sequoia 3rd Gen (2023-2025), Tacoma 4th Gen (2024-2025), Land Cruiser 250 Series (2024-2025), and 4Runner 6th Gen (2025-2026).
