Futaba 4EX/4YF Spring Replacement Kit - Restored Stick Tension  [4EX_4YF_spring]

Replacement Springs for Futaba 4EX/4YF

This Futaba 4EX/4YF spring set is made to bring back crisp stick centring and steady control feedback in your transmitter. Specifically matched to the 4EX and 4YF models, the kit helps keep your inputs predictable whether you are racing or cruising.

Improved Stick Response

Each spring is sized to seat correctly in Futaba 4EX and 4YF control arms, delivering firmer, more consistent tension. Swapping out tired springs sharpens control sensitivity and reduces deadband for tighter handling on track or trail.

Durable Construction

Manufactured from resilient materials, the Futaba 4EX/4YF spring set resists fatigue from frequent use. That durability means fewer service jobs and more time running your model with stable transmitter performance.
