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 consistency
- 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 only two 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
Chassis.
The all-new chassis has been significantly narrowed and reconfigured to match the new bulkheads and lower arms, and integrate with the new one-piece aluminum servo/steering mount and the new motor mount position, moving the mount 5mm forward to generate more traction.
Motor Mount.
The new motor mount has been repositioned 5mm forward for more traction. The clamping screw is moved closer to the motor to create space for the new steering arm.
Servo Mount.
All-new one-piece servo mount moves the servo 5mm more forward for improved traction. The single steering arm saves weight. The servo mount works as part of the battery holder system that moves the battery forward for better traction.
The one piece design of the servo mount eliminates servo movement in serious crashes. The servo mount features an ultra-low design to save weight, and to lower CG as much as possible.
Weight Savings.
The X4F’25 is 25g lighter than X4F’24. In addition to the overall weight savings, the rear suspension has been strategically lightened to shift the weight bias even more to the front tires. Additionally, all the electronics have been moved 5mm forward for additional weight bias improvements to maximize traction.
Thanks to the lightened design, racers have greater weight distribution options for easier adaptation to different track conditions.
Steering Arm.
All-new steering arm was simplified from 6 components into 1 single component for additional weight savings.
Bumper Weight.
The included 100g weight can be placed in the bumper for improved traction in lower traction conditions. For high traction conditions, optional 50g weights can be placed under the front drive train.
Bulkheads.
The bulkheads feature a higher ARS link mounting position allowing greater adjustment possibilities, the horizontal orientation allows moving the ARS link frontwards or backwards to alter rotation characteristics.
Upper Arm Holder.
All-new graphite rear upper arm holder replaces the previous aluminum pieces to reduce weight. The holder is one of many rear suspension components that were strategically lightened to shift the weight balance forward.
The most frequently used alu caster bushings are now included in the kit for the maximum performance right out of the box.
Rear Body Mounting System.
The extra thick 4mm graphite rear body post holder improves durability and stability from the reduced body post flex.
The body post holder features 6 holes with 1.4mm spacing for the rear body posts plus a second bulkhead mounting position between the 1.1mm spacing for easier and more precise mounting of the included horizontal rear body posts.
Upper Arms.
All-new solid composite upper arms have increased flex that generates more traction, beneficial for FWD in most conditions. The added flexibility provides improved durability in serious crashes as well.
Drive Belts.
The X4F’25 uses a shorter drive belt to work with the new layshaft position that is moved 5mm forward for improved traction.
The 1-belt 2WD drivetrain concept provides maximum efficiency featuring 3mm narrow drive belt that has been specially ground for minimal thickness and maximum flexibility.
Top Deck.
All-new top decks match the new layshaft position. The rear top deck now uses only one pair of mounting screws for increased flex, resulting in improved rotation.
The front top deck is now without the cut-out to improve steering precision.
