Use the supplied pair to replace worn front knuckle arms or to restore original geometry after damage, verifying fit before finalising setup.

Are these knuckle arms a direct bolt-on replacement for MR-04 models?

The item is listed for MINI-Z MR-04 compatible models; verify the part numbers and trial-fit to confirm direct replacement on your specific MR-04 variant.

What hardware is included in the pack?

The packing includes two front knuckle arms only; mounting screws or bearings are not listed as included.

What materials are used and why does it matter?

The part is described as 4140 carbon steel and 7075 alloy; these materials are common in RC parts for their balance of strength and dimensional stability under load.

Should I change my setup after installing these arms?

After replacement, check front alignment and suspension movement; small setup adjustments may be needed to restore your prior handling characteristics.
