The GPM MB013 replaces the standard rear gear box tower on the HPI Minizilla with a tougher alloy alternative, aimed at increasing resilience and helping maintain drivetrain integrity during hard use.
The alloy construction provides improved resistance to impact and wear compared with plastic originals, giving drivers steadier rear behaviour when tackling rough surfaces or jumps.
All required screws are supplied with the tower for an efficient installation process, enabling a quick upgrade that gets you back on track faster.
