This GPM aftermarket chassis is an RC-scale replacement part produced for HPI Savage 21 platforms, supplied as a pair with mounting screws. The item is written to match the HPI Savage 21 mounting layout and serves as a direct swap to the factory chassis in typical repair or upgrade workflows.
The chassis uses Alloy-7075 in a 3mm thickness as indicated in the product name, and it is intended to hold the vehicle's drivetrain, suspension pick-up points, and electronics mounts in their factory positions. When swapping the chassis, verify alignment of mount points and the clearance around the motor, ESC, servo, and suspension components before first run.
This chassis is intended as a like-for-like replacement or a stable baseline for handling adjustments on HPI Savage 21 scale RCs, providing the described alloy construction and included fasteners to restore or prepare a vehicle for tuning and maintenance.
