MiniZilla Aluminum Rear Gearbox by 3Racing LA-12/PU - Sturdy Track Upgrade  [LA-12/PU]

Strengthen your MiniZilla with an aluminium rear gearbox

The MiniZilla Aluminum Rear Gearbox by 3Racing LA-12/PU is engineered to boost the durability and lifespan of Hot Bodies MiniZilla models. Machined from quality aluminium, this gearbox resists wear far better than stock plastic units, helping your car survive hard laps and heavy bashing while keeping gear alignment stable under load.

Advantages of swapping to aluminium

An aluminium gearbox brings a strong strength-to-weight balance, so you gain toughness without a big weight penalty. The stiffer housing reduces flex around the gears, which helps maintain smoother power transfer and steadier handling during high speed runs.

Fitting advice and routine care

Fitting the rear gearbox is approachable for most hobbyists using basic hand tools. Check mesh, tighten fasteners to spec but avoid overtorque, and repack bearings and gears with fresh grease as part of routine checks to keep the unit performing reliably.
