Upgrade Steering Geometry for MR-03 with Kyosho MZW412B

The Kyosho MZW412B SP Long King Pin Ball Set is a straightforward upgrade that tightens steering feedback on Mini-Z MR-03 models. By swapping out the stock king pin balls, drivers can achieve cleaner entry and steadier mid-corner lines.

Where It Fits

This set is designed around the MR-03 steering components and is ideal for those maintaining or tuning their Mini-Z. Fitment is aimed at MR-03 style knuckles and steering posts to deliver improved tracking.

Quick Installation Guide

Fitting the MZW412B is simple: remove the old balls, clean contact surfaces, and install the new set. No uncommon tools are necessary, and a short setup check after installation ensures correct steering geometry.
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 these on modified MR-03 chassis?

They work with standard MR-03 steering arrangements; heavily modified chassis may need measurement to confirm fitment before buying.

Will the upgrade change steering feel a lot?

Expect firmer and more precise steering rather than a dramatic change; the set reduces play so feedback is more direct during cornering.

Any maintenance after fitting?

Keep the area free from grit, check for loosening screws, and re-lubricate moving contact points occasionally to maintain smooth operation.
