XRAY 300204 - X4F 2025 - 1:10 EP Touring Kit - FWD

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
Servo Mount

All-new one-piece servo mount moves the servo 5mm forward for more traction
Single steering arm mount reduces weight
Works together with the new battery holder system to move the battery position further forward for maximum traction
One-piece design eliminates servo movement in hard crashes
Ultra-low profile design reduces weight and lowers the CG as much as possible
Steering Arm

All-new steering arm redesigned for weight savings
New geometry creates clearance to move the motor mount and servo mount 5mm forward for improved traction & improved in-corner steering
Weight Saving

X4F’25 is 25g lighter than X4F’24 with strategic lightening of the rear suspension to move the weight bias further forward
All electronics moved 5mm forward for maximum front traction
Greater weight distribution set-up options to better adapt to different track conditions
More All-new Features

100g front bumper weight for improved traction in lower grip conditions. For high traction conditions, optional 50g weights can be placed under the front drivetrain
All-new rear bulkheads contribute to additional weight savings
Rear bulkheads’ higher ARS link mounting position creates greater adjustment possibilities, and allows for mounting of the ARS link more forward or backward, which has a big effect on the car’s rotation

All-new graphite rear upper arm holder reduces weight
Graphite rear body post holder improves durability and durability
New composite upper arms generate more traction and improve durability in hard crashes
Shorter belt matches the forward layshaft position
Updated top deck geometry matches the new layshaft position
Rear top deck uses a pair of mounting screws for improved rotation
Most popular caster bushings included in the kit for maximum performance right out of the box
All-new battery mounting system works with the new servo mount to position the battery in a maximum forward location for improved traction
Medium hubs included in the kit to generate more traction and steering for maximum performance right from the box
All-new motor mount moves the motor 5mm forward to improve traction
1mm shims under the front lower arms improve steering
Active rear towers improve rotation, and the new shock design allows lower downstop settings without any need for modification
New suspension arms with relocated shock positions improve lower arm flex and reduce twist under load
Inner shock locations improve weight distribution with the shocks closer to the vehicle mid-line
Lower arms use under arm anti-roll bar mounting and reduce shock height by 4.5mm for ultra-low CG
Upper arms are shaped for clearance around the new shock position while maintaining proper suspension geometry and rigidity
Front and rear shock holders use shims to adjust shock positions in finer increments
Three different shock holder mounting options provide chassis flex alternatives to tune responsiveness and grip
Active or fixed rear shock holder configurations provide two dampening alternatives in one mount
Simplified shock absorber installation uses a fixed set screw to secure the threaded shock mount stud and prevent movement in the mount during maintenance
Front steering plates with improved Ackermann positions integrate with the new arms and shock positions and new single steering arm
Rear ARS plates move the link forward for improved rotation
Improved ECS drive shaft case uses a C-clip to secure a new aluminum sleeve that captures the coupler pins without the use of set screws for improved reliability and easy assembly
Bulkhead anti-roll bar locations are moved lower, along with a new ARS link position on the rear bulkheads, to match the improved suspension geometry
