HPI Bullet 3.0 Compatible Front Knuckle Arm Alloy BMT021 by GPM  [BMT021]

Front alloy steering knuckle for Bullet 3.0

This alloy front knuckle arm is made for use on HPI Bullet 3.0 MT and ST chassis and is supplied as a single pair. It serves as a robust aftermarket option for replacing bent or tired plastic knuckles.

Functionally the knuckle positions the wheel hub and converts servo motion from the steering linkages into wheel angle. Installing an alloy arm can tighten up slack at ball joints and provide a more positive seating for pins and bearings used on Bullet 3.0 setups.

Fitment advice: confirm which side is left or right, decide on reusing or renewing pins and bushings, and test steering sweep after assembly. Typical RC hand tools like hex keys and needle nose pliers will be enough for the swap.

Use this alloy knuckle when you want firmer steering and reduced joint play on HPI Bullet 3.0 MT/ST models during recreational or club running.
