Rear-End Stability Upgrade with Kyosho VZW439

Looking to tighten up rear grip? The Kyosho VZW439 brass rear suspension holder is a compact upgrade for the V ONE R4 Evo. and R4sII that adds about 10g to the chassis to improve traction and balance.

What Brass Adds to Your Setup

Brass provides concentrated mass and long-term durability. That extra weight helps lower the centre of gravity and keeps the rear tyres loaded through aggressive turns, which is helpful for drivers wanting predictable handling.

Fitment Details and Simple Swap-In

The Kyosho VZW439 is made to integrate cleanly with the V ONE R4 Evo. and R4sII platforms, so most hobbyists will find installation straightforward. It is a low-effort change that can bring noticeable handling refinement.
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.

How does 10g change chassis balance?

The weight shifts load rearwards and reduces pitch, which tends to stabilise cornering and improve traction on exits.

Can I use this with stock electronics and batteries?

Yes, the holder is a passive component and works with standard electronics and battery layouts used in the R4 platforms.

Should I recheck setup after fitting?

Always double-check suspension geometry and ride height after installation to confirm the change matches your setup goals.
