Durable Knuckle Arm Upgrade for TF Models

For those tuning their TF rigs, the Kyosho TF243B knuckle arm provides a clear durability upgrade while preserving handling geometry. It is made for the TF7.7 and TF6 SP chassis and uses a thicker plastic profile compared with the original TF243 design.

Notable Attributes of the TF243B

  • Compatibility: Manufactured to fit TF7.7 and TF6 SP chassis without modification.
  • Reinforced Design: Increased section from 3mm to 4.5mm for better durability during hard running.
  • Matching Geometry: Retains the same hole locations as the TF243 so alignment and linkages remain unchanged.
  • Race Ready Upgrade: Ideal for drivers who want fewer failures during practice and race sessions.
Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I use TF243B on a modified chassis?

If the chassis retains the TF7.7 or TF6 SP mounting points, the TF243B will fit; extensively modified layouts may need custom mounts.

Does the thicker material affect steering feel?

The geometry is unchanged so steering characteristics remain similar, while the added thickness reduces flex and potential breakage under load.

Is any trimming required on fitment?

No trimming is typically needed because the TF243B matches the TF243 hole pattern and mounts directly to the specified TF chassis.
