Precision Aluminium Front Gearbox for Setup-Oriented Builds

The 3Racing LA-11/PU aluminium front gearbox is manufactured to deliver a consistent, rigid mounting platform for the Hot Bodies MiniZilla drivetrain. Its aluminium construction reduces housing deflection under load, helping maintain true gear mesh and predictable transmission behavior during aggressive runs.

Racing-Focused Advantages

For competitors seeking repeatability, an aluminium gearbox provides a firmer interface for bearings and shafts, which lowers tolerance stack and supports finer gear mesh adjustments. The purple anodise protects surfaces while keeping components serviceable for frequent track maintenance.

Installation and Setup Recommendations

Install the 3Racing LA-11/PU using recommended torque settings and verify pinion to spur engagement at static and dynamic conditions. Small mesh adjustments and a follow-up run-in sequence will stabilise gear seating and reduce initial backlash.

How does aluminium affect gear mesh during tuning?

Aluminium limits housing flex, so mesh changes are more repeatable. This consistency lets you dial in smaller mesh clearances without unexpected movement under load.

Are there setup changes needed after switching from plastic?

Expect to recheck pinion height and fastener torque. The stiffer housing can change vibrational characteristics, so verify electronics and motor mounts for any new clearance requirements.

What maintenance routines suit racing use?

Perform pre-event inspections of gear mesh and bearing play, keep surfaces clean of debris, and replace worn internal parts promptly to maintain peak performance.
