Metal rear knuckle for TT02 hub assemblies

This aftermarket rear knuckle arm is produced for use on the TAMIYA TT02 chassis and supplied as a 1 pair set with bearings. Forged in aluminium, the part replaces the factory plastic knuckle to provide a stiffer support for the rear hub and wheel axle assembly.

Fitment covers TT-02 platform variants that use the same rear hub geometry. The included ball bearings reduce spindle friction compared with plain bushings, helping to keep wheel spin smoother under load during tuning and track runs.

Installation notes: the unit installs into the same position as the stock knuckle and is made to accept the original fasteners and axle pin layout. Check hex screws and pins for wear before refitting, and confirm wheel hex engagement and axle retention once fitted. No special parts are normally required for a standard TT-02 rear hub conversion.

Tuning use: this alloy knuckle arm is aimed at hobbyists seeking a metal replacement to increase durability and give more predictable suspension response during setup changes and testing.

Specifications

  • Item: Rear knuckle arm with bearing, 1pr set
  • Material: Aluminium alloy
  • Model Number: GPM TT2022B
  • Compatibility: TAMIYA TT02 chassis

Opt for this aluminium rear knuckle arm when you want a tougher, more consistent pivot point for regular tuning and endurance in TT-02 rear hub setups.

Is this a direct swap for the stock knuckle?

Yes, for TT-02 variants with the standard rear hub geometry it is a direct replacement using the same mounting points.

What maintenance do the bearings need?

Periodic cleaning and light lubrication will keep the bearings performing; inspect for play or roughness and replace bearings when wear becomes evident.

Will this reduce drivetrain friction?

Fitted bearings reduce rotational friction at the spindle compared with bushings, which can yield smoother wheel rotation under load.

Can I use this on competition setups?

Yes, it is suitable for club and entry-level competition use where a more rigid pivot point and consistent suspension behaviour are desired.
