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

Front alloy knuckle for HPI Bullet 3.0 platforms

An alloy front knuckle arm supplied as a 1 pr set, engineered as an aftermarket replacement for HPI Bullet 3.0 MT and ST chassis. It is intended to recover steering accuracy after damage or wear to the original parts.

The knuckle locates the front hub and passes steering input from the servo through the linkages to the wheel. Upgrading to alloy helps reduce play at joints and offers a firmer seating for pins and bearings commonly used on the Bullet 3.0 range.

Fitment advice: confirm left/right orientation, consider replacing worn pins and bushings, and check steering sweep and toe after installation. Use standard RC hex drivers and pliers and ensure bearing clearances are correct before final tightening.

A practical upgrade for HPI Bullet 3.0 MT/ST owners looking to regain steering precision or increase front end rigidity for everyday running and servicing.
