The JR-LB01-GU pack contains four aluminium body mounts in a gun metal finish, intended for Tamiya Lunch Box scale bodies. These replace softer plastic mount pieces to provide a firmer seating for the vehicle's body posts.
Designed to improve consistent body retention and repeatable alignment, the aluminium construction reduces elastic movement at the mounting points so fitment remains stable over multiple runs. The gun metal finish offers a subtle metallic look that complements scale styling without adding bulk.
Installation is straightforward: remove the original mounts, position the aluminium parts on the same post locations, and secure with the stock hardware. They serve as direct-replacement tuning parts to limit body play and aid repeatable setup.
