The GPM MB013 is a precision alloy replacement tower for the HPI Minizilla rear gear box, intended to raise structural strength and reduce flex in the rear assembly under load. The design focuses on reliable alignment and consistent drivetrain behaviour during demanding use.
Using a robust alloy construction, this tower increases resistance to impact and wear relative to stock plastic components. The result is improved rear-end stability and reduced risk of deformation during intense running sessions.
The product is supplied with the necessary fasteners for direct installation, minimising downtime when fitting the upgrade. The straightforward hardware package supports efficient field upgrades and routine maintenance cycles.
