MiniZilla Aluminum Rear Gearbox by 3Racing LA-12/PU - Race Grade Replacement  [LA-12/PU]

Race oriented aluminium rear gearbox for MiniZilla

The MiniZilla Aluminum Rear Gearbox by 3Racing LA-12/PU is developed to provide consistent drivetrain behaviour for competitive MiniZilla applications. The aluminium construction reduces housing deflection under torque, delivering steadier gear mesh during aggressive acceleration and braking phases.

Performance focused benefits

Aluminium increases rigidity around bearing seats and mounting points, which helps maintain pinion and spur alignment through heat cycles and sustained loads. This lowers the chance of transient gear lash and improves repeatable lap times.

Installation and tuning notes for racers

Fitment is straightforward but verify alignment with a dial or feeler method and set mesh to minimise backlash without binding. Pair the LA-12/PU with sealed high quality bearings and a medium grease on gears for reliable service under race conditions.
