Alloy front knuckle for HPI Bullet 3.0 steering

This replacement front knuckle arm fits HPI Bullet 3.0 MT and ST chassis and is supplied as a 1 pr set. It is an aftermarket alloy unit meant to restore steering alignment and stiffness on worn or damaged steering assemblies.

The knuckle locates the front hub and transmits servo and linkage movement to the wheel. Upgrading from stock plastic to an alloy arm helps reduce play at ball joints and bearing seats, giving a firmer steering feel on typical off road surfaces.

Installation tips: confirm left and right orientation, decide whether to reuse existing pins and bushings, and check steering geometry after fitting. Standard RC tools such as hex drivers and pliers are sufficient; verify smooth bearing and pin action before final setup.

Specifications

  • Item: Front knuckle arm, 1 pr set
  • Material: Alloy
  • Model Number: BMT021
  • Compatibility: HPI Bullet 3.0 MT and ST

Choose this alloy front knuckle arm when you need to recover steering precision on HPI Bullet 3.0 MT/ST rigs or when moving from plastic parts for added rigidity during running and maintenance.

What comes in the box

One pair of front alloy knuckle arms sized for the HPI Bullet 3.0 MT and ST chassis is included.

Can I reuse my old pins and bearings

You can reuse good condition pins and bearings, but replacing worn hardware is recommended to avoid play after fitting the new alloy knuckles.

Do these knuckles change steering geometry

They are a direct replacement and should not alter geometry if installed in the original orientation, but always recheck toe and trim after installation.
