Control Arm Lower

The Whiteline Performance control arm lower trailing arm is engineered for drivers who demand precise rear suspension geometry and durability in demanding conditions. This OEM-replacement rear lower control arm is manufactured for 2008–2020 Subaru applications and sold as a pair, making it the complete solution for restoring factory alignment and handling characteristics. Whether you're replacing worn suspension components, upgrading for improved track performance, or maintaining vehicle stability after heavy use, this steel control arm delivers the geometry and strength required for reliable operation.

Constructed from high-strength steel with a silver powder coat finish, the Whiteline control arm lower resists corrosion and UV degradation in all weather environments while maintaining consistent structural integrity under load. The powder coat surface protects against salt spray, moisture, and road debris—critical in regions with harsh winters or coastal conditions. Whiteline's engineering ensures precise ball joint interfaces and bushing mounting points, preserving OEM suspension kinematics and preventing alignment drift during acceleration, braking, and cornering. The steel construction absorbs impact energy effectively, reducing transmitted vibration to the chassis and improving ride quality over rough terrain.

This control arm lower is ideal for Subaru owners operating their vehicles in performance driving, off-road, or high-mileage scenarios where suspension geometry consistency is non-negotiable. The pair configuration eliminates the need for separate left and right purchases and ensures balanced suspension behavior across both sides. Installation requires basic suspension work and alignment verification post-installation; professional fitting is recommended to achieve factory specifications. Compatible with all listed 2008–2020 Subaru models, this trailing arm serves as a direct OEM replacement that restores factory performance and longevity.
