This hydraulic power steering rack and pinion assembly is designed as a direct replacement for select Toyota vehicles, including the 2004-2008 Toyota Solara. It is built from aluminum alloy with 45# steel gears and a 40Cr alloy housing for durable, corrosion-resistant performance. The assembly is engineered for responsive, stable steering and includes a fully enclosed dust boot to help protect internal components. Pre-installed inner tie rods and direct OE replacement fitment help simplify installation. It is intended for left-hand-drive vehicles only.
