The Kyosho VZW437-2 Aluminium Servo Saver replaces standard plastic parts with a tougher metal unit to sharpen steering response for club and competition use.
The added 2mm length provides clearance for modern brushless servos and helps prevent binding, improving steering accuracy during fast laps.
Shaped to suit the V-One R4 Evo and R4sII chassis, the Kyosho VZW437-2 installs cleanly and supports consistent steering behaviour across sessions.
