This GPM replacement is a CNC-profiled graphite chassis plate engineered for HPI Savage 21 applications and supplied as a 1pr set with mounting screws. The 3mm graphite section is manufactured to replicate factory mounting geometry and provide predictable stiffness for tuning and upgrade use.
As a precision structural component the plate offers a stable platform for drivetrain and suspension attachments, influencing torsional rigidity and dynamic response. Install using the original mounting points where possible, aligning holes before progressive torqueing to protect threaded inserts and minimise stress concentrations in the graphite.
Recommended for hobbyists seeking a precise graphite replacement or a predictable stiffness change on Savage 21 platforms; adhere to standard assembly practice and torque limits to maintain insert life.
