These lower arms are built using a newly developed stamping mold based on the factory shape, with the steel thickness increased from 2.8mm to 3.0mm. The end stopper is designed with three holes and a movable reinforcement plate.
The added rigidity provides improved front stability and more precise steering control.
Conventional modified lower arms often require cutting, length adjustments, and rewelding of the factory arm, which can create concerns about strength and left-right consistency. By using a custom stamping mold and making each part thicker than the factory version, these arms achieve strength that exceeds OEM quality.

By the time you source used LCAs, replace ball joints, install new bushings, and modify bump stops or extension plates, you’re already close to the cost of importing these arms from Japan. These units arrive fully equipped with brand-new bushings and are stamped from 3mm thick steel plate for exceptional strength over factory. Built for durability and consistent performance, they provide a reliable, bolt-on upgrade that eliminates the compromises of modified factory arms.
