Replacement front knuckle arm for MINI-Z MR-04

This front knuckle arm is an aftermarket replacement for the KYOSHO MINI-Z MR-04 chassis and is listed as MR04021. It combines 4140 carbon steel with 7075 alloy to give a durable front knuckle solution for compatible MR-04 Mini-Z models.

The pack supplies two knuckle arms for left and right sides of the front suspension. Install them for maintenance or after damage to restore proper steering geometry. The materials choice is intended to reduce wear and help maintain alignment through typical Mini-Z use.

Replace both front knuckles with the supplied pair to recover factory geometry or to continue running after impact, checking steering clearance and travel after fitment.

Do I need bearings with these knuckles?

This item ships as two knuckle arms only; reuse your existing bearings and fasteners or buy replacements that match the original sizes.

Will MR04021 change suspension geometry?

Parts that match original dimensions should not significantly alter geometry, but always verify toe and camber after installation and make small setup changes if needed.

What advantages do 4140 and 7075 offer?

4140 steel and 7075 alloy are chosen for a balance of strength and stiffness while keeping precise fitment, which helps maintain handling consistency in small-scale RC applications.
