X4F'27 – New Features

XRAY X4F'27 All-new Features

New gear differential with lightweight & ultra-reliable designNew front bulkhead flex adjustment system provides a wide range of flex settings for different track conditionsNew one-piece short lower CFF2 suspension arms specially designed for X4F increase suspension rigidity and improve overall handling, response, and maximum steeringNew ultra-low anti-roll bar system reduces the center of gravity and improves anti-roll bar performanceUpdated smaller suspension pivot balls reduce weight and increase roll-center tunabilityNew carbon fiber steering plates with optimized geometry and flex characteristics to reduce weight and increase mechanical tractionNew carbon fiber ARS plates with two rear link mounting positions to optimize rear suspension geometry and flex characteristics, reduce rear suspension weight, and expand ARS setup adjustmentNew 2.2mm carbon chassis with rear cut-outs integrated with the carbon flex brace system to provide multiple rear flex settings for different track conditionsNew strategically positioned center chassis cut-outs to optimize flex, increase traction and steering response, reduce weight, and expand weight distribution tuningRedesigned carbon fiber rear body post holder integrated with the upper clamp for an ultra-durable compact designUpdated top decks optimized for flex characteristics and compatible with the optional alu braces to expand the flex adjustment alternativesNew rear bulkhead flex adjustment system provides a wide range of rear flex settings for different track conditionsUpdated 1mm higher shock holders repositioned to complement the updated suspension geometry, increasing suspension travel and providing three flex adjustment positionsNew aluminum ARS posts mounted directly to the chassis instead of the bulkheads to improve steering & rotationRedesigned CFF upper arms with optimized flex characteristics provide more consistent handlingRedesigned lightweight carbon fiber upper clamps for lower CG & optimum flex for more consistent handling, while maintaining maximum crash durabilityUpdated smaller differential bearings for reduced weight and lowered center of gravityRedesigned servo mount with countersunk holes for perfect fitment also with thinner chassis typesNew front chassis brace provides quick and easy front flex adjustmentsRedesigned motor mount with countersunk holes for perfect fitment also with thinner chassis typesNew aluminum front chassis brace with multiple mounting configurations for extensive front chassis flex tuningAdjustable front brace settings optimize the balance of steering response, corner speed, forward traction, and drivability in all different track conditionsNew 30g front bumper weight optimizes front-end weight distribution to reduce weight transfer during acceleration and braking for improved front-end stability and consistent handlingNew 40g front side weights mounted under the front drivetrain increase rotation and corner speed while maintaining predictable handlingNew ultra-lightweight 3D-printed rubber bumper with an H-profile design provides durable crash resistance, optimized compression characteristics, increased airflow under the body, improved front traction, and fitment for the 30g front bumper weightCarbon rear chassis brace features three rear flex settings—soft without braces, medium with O-rings, and stiff with fully connected braces—adjust steering response, rotation, mid-corner steering, stability, and drivability for different track sizes and traction conditions
