XRAY X4F’27 All-new Features
New gear differential with lightweight & ultra-reliable design
New front bulkhead flex adjustment system provides a wide range of flex settings for different track conditions
New one-piece short lower CFF2™ suspension arms specially designed for X4F increase suspension rigidity and improve overall handling, response, and maximum steering
New ultra-low anti-roll bar system reduces the center of gravity and improves anti-roll bar performance
Updated smaller suspension pivot balls reduce weight and increase roll-center tunability
New carbon fiber steering plates with optimized geometry and flex characteristics to reduce weight and increase mechanical traction
New 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 adjustment
New 2.2mm carbon chassis with rear cut-outs integrated with the carbon flex brace system to provide multiple rear flex settings for different track conditions
New strategically positioned center chassis cut-outs to optimize flex, increase traction and steering response, reduce weight, and expand weight distribution tuning
Redesigned carbon fiber rear body post holder integrated with the upper clamp for an ultra-durable compact design
Updated top decks optimized for flex characteristics and compatible with the optional alu braces to expand the flex adjustment alternatives
New rear bulkhead flex adjustment system provides a wide range of rear flex settings for different track conditions
Updated 1mm higher shock holders repositioned to complement the updated suspension geometry, increasing suspension travel and providing three flex adjustment positions
New aluminum ARS posts mounted directly to the chassis instead of the bulkheads to improve steering & rotation
Redesigned CFF™ upper arms with optimized flex characteristics provide more consistent handling
Redesigned lightweight carbon fiber upper clamps for lower CG & optimum flex for more consistent handling, while maintaining maximum crash durability
Updated smaller differential bearings for reduced weight and lowered center of gravity
Redesigned servo mount with countersunk holes for perfect fitment also with thinner chassis types
New front chassis brace provides quick and easy front flex adjustments
Redesigned motor mount with countersunk holes for perfect fitment also with thinner chassis types
New aluminum front chassis brace with multiple mounting configurations for extensive front chassis flex tuning
Adjustable front brace settings optimize the balance of steering response, corner speed, forward traction, and drivability in all different track conditions
New 30g front bumper weight optimizes front-end weight distribution to reduce weight transfer during acceleration and braking for improved front-end stability and consistent handling
New 40g front side weights mounted under the front drivetrain increase rotation and corner speed while maintaining predictable handling
New 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 weight
Carbon 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
2027 All-new Features.
Chassis
All-new carbon chassis with mid and rear cut outs creates flex that generates more rotation and steering.
This 12g weight reduction from the cutouts means more ballast weight can be positioned on the chassis to alter weight distribution.
Upper clamps & arms
Redesigned carbon rear upper holder improves durability in hard crashes. The carbon plate utilizes a new wave design, instead of the previous fixed cross member, which allows more flex in the rear suspension to improve rotation and off-power steering.
Link style upper suspension arms included in the kit as an alternative to the traditional CFF upper arms for maximum adjustability & improved handling in certain conditions.
Shock absorbers
Shorter shocks, positioned 3mm lower than previous geometry, improve cornering speed, mid-corner steering and stability, and reduce traction rolling in high traction conditions.
New shock holders relocate the upper shock mount positions to compliment shorter shock geometry
Steering system
Redesigned servo mount for the new carbon battery holder
All-new adjustable steering arm provides easy Ackermann tuning by changing eccentric bushings
More all-new features
New rear top deck with a more open rear section improves rotation and off-power steering
Carbon battery holders improve the look of the car
All-new wave design carbon body post holder allows more rear suspension flex that improves rotation and off-power steering
Chassis
All-new chassis redesigned to work with the new bulkheads & lower arms
Moves motor mount location 5mm forward for improved traction
Integrates with the new one-piece aluminum servo/steering mount and battery holder systems
Narrowed 5mm in the front and 10mm in the rear for improved flex characteristics that improve steering and rotation while also reducing chassis drag for improved cornering speed
Upper Arm Holder.
Redesigned carbon rear upper arm holder improves durability in hard crashes. The carbon plate utilizes a new wave design, instead of the previous fixed cross member, which allows more flex in the rear suspension to improve rotation and off-power steering.
XLP vs XLP2.
All-new XLP2 shocks are 4mm lower compared to the previous XLP, improving cornering speed, mid-corner steering and stability, and minimizing traction rolls in high traction conditions.
Shock Holders.
Made possible by the shorter XLP2 shocks, new shock holders relocate the upper shock mount position 4mm lower. The new geometry improves cornering speed, mid-corner steering and stability, and reduces traction rolling in high traction conditions.
Upper Link Arms.
All-new link style upper suspension arms are included in the kit as an alternative to the traditional upper arms for maximum adjustability & improved handling in certain conditions
Steering Arm.
All-new adjustable steering arm provides easy Ackermann tuning by changing the eccentric bushings.
