Precision front knuckle arm for MINI-Z MR-04

This precision front knuckle arm is engineered for the KYOSHO MINI-Z MR-04 chassis and designated MR04021. Manufactured with a combination of 4140 carbon steel and 7075 alloy, the component is intended as a direct service replacement for the front knuckle area on compatible MR-04 Mini-Z models.

The delivery includes two knuckle arms to replace both sides of the front suspension. Use these parts during scheduled maintenance or after impact repair to restore proper steering geometry. Material selection emphasises dimensional stability, wear resistance and consistent fitment under typical Mini-Z operating loads.

Packing includes

  • Front Knuckle Arm - 2pcs

Fit the supplied knuckle pair to maintain or restore correct front geometry; inspect mounting interfaces and secure hardware to nominal torque values for reliable operation.

What manufacturing methods are used?

Materials are specified for CNC-friendly production and tight tolerances; finishes and machining control ensure repeatable fitment across production batches.

Are there recommended torque values?

Follow the original chassis hardware torque guidelines where available; apply threadlocker selectively and avoid over-torquing to prevent fastener or part damage.

How does material choice affect performance?

4140 steel offers fatigue resistance while 7075 alloy balances strength and weight; together they provide dimensional rigidity and resistance to wear for improved service life in scale suspension components.
