Aftermarket Alloy Gearbox for HPI Savage

This purple aluminium gearbox housing is an aftermarket replacement for the HPI Savage Nitro Off Road Series. The alloy construction increases stiffness compared with the stock plastic housing and provides a rigid mounting point for spur and pinion alignment while supporting drivetrain parts during demanding use.

Intended use: chassis durability and consistent setup. An aluminium housing helps preserve gear mesh under load and simplifies spur height and bearing changes. The product is the housing only and does not include internal gears or bearings.

Fitting notes: remove the original housing and transfer bearings and gears into the alloy unit. Reuse compatible fasteners where possible and confirm mesh and backlash after assembly. Check screw lengths and any shims before final tightening to prevent motor pinion or spur interference.

Compatibility

  • HPI Savage Nitro Off Road Series

This alloy gearbox housing is suited to builders who want a more rigid gearbox shell for steady drivetrain alignment on HPI Savage kits, delivering consistent behaviour without changing internal gear ratios.

Will stock internals fit the alloy housing without modification?

Yes, the housing is designed to accept the standard gears and bearings used in Savage models without additional machining for typical configurations.

Is any extra hardware supplied with the housing?

The item is supplied as the aluminium housing only; reuse OEM screws or fit equivalent replacements as needed to secure the housing correctly.

Does the anodised finish affect fitment or cooling?

The purple anodised finish is cosmetic and does not affect dimensional fit. Aluminium will conduct heat better than plastic, but overall cooling depends on motor placement and airflow.

What checks should I perform after installing this unit?

After fitting, rotate the drivetrain to check for smooth operation, verify gear mesh and backlash, and perform a brief test run at low speed to confirm there is no binding or unusual noise.
