This aluminium rear lower suspension arm is supplied as an aftermarket replacement intended for TL-01, GF-01 and WR-02 layouts that share the same rear lower arm mounting pattern. It is provided as a single unit to replace the factory plastic lower arm where the mounting geometry matches the listed models.
The aluminium construction modifies linkage stiffness and pivot wear characteristics relative to molded plastic. The arm is designed to align with the chassis original mounting points and common hardware; installers should trial-fit and reuse compatible screws and pins when appropriate.
From a hobbyist perspective, the arm is selected to give predictable rear-end feedback and improved service life under repeated loading. Check full suspension articulation and confirm no interference after installation to ensure correct operation.
