12mm alloy hex insert for HPI Bullet MT/ST

This alloy hex adapter is made for HPI Bullet Fluorescent MT and ST models to convert wheel hex interfaces. The component is supplied as a 4pcs set and matches a 12mm diameter with 9mm thickness where that specific hex seat is required.

Fitment is simple for experienced hobbyists: take off the original hex or hub, locate the alloy insert onto the wheel or axle hex, and fasten using the existing bolts or nuts. Perform a dry fit and ensure the adapter sits flush to avoid runout.

Use this adapter during setup to alter the wheel mating surface without swapping axles or gearbox parts, useful for adjusting track width or wheel positioning. Always confirm clearance with nearby components and test assembly before full use.

Which models is this adapter compatible with?

Compatible with HPI Bullet Fluorescent MT and ST platforms where the wheel hex requires a 12mm diameter and 9mm thickness adapter. Measure your current hex to be sure.

How many adapters come in the set?

The item ships as a set of four alloy hex adapters to cover all four wheels on a typical 4WD model.

What should I check after fitting?

After installation check for tight seating, minimal play, and full wheel rotation without rubbing on suspension, body mounts or brakes.
