Kyosho VZW447 Front FTT One-Way Unit  [KY-VZW447]

Track tuning with the Kyosho VZW447

The Kyosho VZW447 FTT Oneway Unit is a purpose-made upgrade for V-ONE R4 series cars. Swapping this into the front differential position improves traction on corner exit and gives firmer acceleration response for lap time gains.

Oil-controlled engagement for better exit speed

Silicone oil inside the unit governs its engagement characteristics, cutting down on unpredictable movement while braking. The result is a smoother transfer of power and more consistent exits from bends.

Simple upgrade for V-ONE R4 chassis

Designed with racers in mind, the Kyosho VZW447 fits V-ONE R4Evo.2 and R4sII models and integrates without major modifications. It is a straightforward way to alter front-end dynamics during tuning sessions.
