This aluminium main chassis is an RC-scale replacement part designed for the YRX12 2019 platform. Machined from 70-75 grade duralumin, the plate measures 2.0mm thickness and is intended to shift mass lower in the car, improving transient response without changing drivetrain components.
The top of the chassis has the Yokomo logo engraved at the battery mounting area, providing a reference for battery placement. The part is supplied as the bare chassis plate with mounting faces and holes positioned to match the supported YRX12 2019 mounting pattern.
Use this chassis when you want a straightforward chassis change that affects balance and steering feel. It is suitable for hobbyists focusing on on-track tuning, normal maintenance swaps, and scale-accurate assembly work. Verify hole alignment against your existing YRX12 2019 parts before installation to confirm fitment.
For builders running a YRX12 2019 setup who want a durable, low-profile chassis plate, this aluminum main chassis provides a direct replacement option that changes weight distribution and steering response while keeping original mounting geometry.
