Product Description

The Whiteline KTA139A adjustable rear lower control arms are engineered to optimize camber settings on late-model Subaru and Toyota performance sedans and coupes. With ±3.5° of on-car adjustment, these heavy-duty arms help improve traction, reduce brake hop, and extend tire life through sharper handling dynamics.

Constructed from high-strength CNC steel, powder-coated for corrosion resistance, and featuring durable bushings, the KTA139A set installs easily using factory mounts. Ideal for lowered or track-driven setups, the twin arms deliver balanced geometry and come backed by a 3-year/60k-mile warranty--making them a reliable upgrade for driving enthusiasts.
