Product Description

The Cusco 187 477 A Type II Front Lower Arm Bar enhances structural rigidity on Lexus GS and Toyota Aristo platforms (JZS160/JZS161) by connecting critical suspension points with a lightweight 4-point crossmember. Its tubular aluminum design helps minimize body flex under load and increases steering accuracy without compromising ride comfort.

Unlike simpler 2-point bars, this Type II model spans four mounting locations for added reinforcement. Powder-coated for durability, it installs cleanly using factory hardware and fits without trimming. It's an ideal upgrade for drivers seeking improved chassis response on both street and track while retaining OEM suspension geometry.
