The GPM SW038B is a precision upgrade for the GMADE GS01 Sawback, replacing the original plastic lower housing with a robust 6061 T6 aluminium unit. Engineered to protect tie rod attachments and the undercarriage, the mount improves impact resistance while keeping mass low to maintain vehicle balance. Installation preserves standard mounting points and the part is compatible with the G-made Sawback GS01 and the G-made Sawback 4LS, providing a durable foundation for further performance upgrades.
