7075-T6 knuckle for enhanced steering durability

Made as an RC-scale hop-up for YIKONG YK7081 TB8 vehicles, this steering knuckle is CNC-machined from 7075-T6 aluminium for improved strength at steering load points while keeping added mass minimal. The item replaces factory part number 80004 and targets users seeking firmer steering feedback and longer bearing life.

The upgrade uses larger bearings: inner 20x30x7mm (stock 20x27x4mm) and outer 15x24x5mm (stock 15x21x4mm). These larger bore and outer dimensions spread load and reduce pressure on bearing contact surfaces, helping the steering assembly remain consistent under repeated impacts without changing core geometry.

All required mounting screws and hardware are included and parts arrive pre-assembled where practical. During installation, apply medium-strength threadlocker to mating screws and observe proper torque values for M3 fasteners to protect aluminium threads from stripping.

  • Steering knuckle, 7075-T6 aluminum body
  • Inner bearings 20x30x7mm, outer bearings 15x24x5mm
  • Mounting screws, pins and M3 nuts included for direct swap

A straightforward aluminium hop-up for TB8-series YIKONG kits, this knuckle is aimed at improving bearing life and delivering firmer steering without complex fitting procedures.

Larger bearings reduce play and bearing stress, which typically results in a firmer, more consistent steering feel under load.
Most users retain existing endpoints; fit the knuckle, check for smooth operation through the full travel, and only adjust radio settings if binding or trim changes are noticed.
The design keeps core chassis geometry unchanged, so ride height and static camber should remain as before.
Run the model gently for the first few sessions and re-check fastener torque; this helps seat bearings and confirm everything remains secure.
