Made in Europe.

Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German and Swiss machines and premium European materials, crafted with XRAY’s trademark attention to detail by our production specialists. The X4 is truly a masterpiece.

X4 Editions.

The X4 is available in three different versions to suit any track.

CFF™ Arms.

Unique CFF™ – Carbon Fiber Fusion upper & lower suspension arms for outstanding handling.

Suspension Mounting.

All suspension components mount directly to the CFF™ arms without additional parts, eliminating play between pieces to ensure accuracy and reliability.

Suspension Arms.

The CFF™ arms make the X4 extremely responsive and sharp, and generate fantastic cornering speed & traction.

Chassis.

The X4 chassis is designed for the new CFF™ suspension concept and adds alignment holes for the centering pins found on all of the X4 bulkheads and motor mount for maximum reliability in a crash.

The symmetric X4 chassis creates equal side to side flex.

The X4 chassis is available in three different flex alternatives suitable for different track conditions.

Motor Mount.

Super-strong one-piece motor mount is placed in the absolute chassis center and features integrated layshaft axle, battery backstops, belt tensioners and new tweak-free top deck mounting.

Battery Backstops.

Integrated battery backstops for standard and shorty packs set the battery position to adjust weight balance and prevent interference with the spur gear.

Belt Tensioners.

Adjustable tensioners ensure proper belt adjustment for maximum drive train efficiency.

Motor Mount Flex Adjustment.

The motor mount is a vital part of the X4 Multi-Flex settings.

Middle Layshaft.

The super-lightweight hollow aluminum layshaft eliminates drivetrain vibration.

Bulkheads.

The new bulkheads feature centering pins for maximum reliability in a crash and raised diff positions for improved cornering speed in high traction conditions.

Centering Pins.

All chassis mounted aluminum framework parts including the bulkheads, motor mount, servo holder, front shock towers and rear body post plates feature centering pins for easy assembly and maximum reliability in a crash.

Upper Clamps.

Upper clamps use caster inserts for quick and easy set-up changes and use centering pins for precise installation and improved reliability in a crash.

Caster.

Aluminum inserts easily set the caster angle for quick and accurate tuning. The 2 dot inserts are included for both front and rear, with 1 and 3 dot inserts available for additional tuning options. In the rear suspension, the inserts can be reversed for even more adjustment possibilities.

Top Deck.

Multi-flex top deck features multiple stiffness settings via a ball-bearing insert and special tweak-free flex screws.

Soft setting:

No bushing or bearing is used. This allows maximum flex and provides maximum steering. However, the car is less stable on-power.

Soft-medium setting:

The top deck is connected to the motor mount via ball bearing. This setting eliminates a bit of steering but improves stability.

Medium setting:

The top deck is connected to the motor mount via special 3×5.5mm screw in the rear, behind the layshaft. This setting eliminates a bit of steering but improves stability.

Stiff setting:
The top deck is connected to the motor mount via special screws M3x5.5mm behind and in front of layshaft. This setting provides maximum stability.

Top Deck Flex Settings.

The unique top deck flex settings allow quick and easy adjustment of chassis stiffness while the well-proven bearing flex setting has been retained for even more adjustability and fine tuning.

Hubs.

Graphite composite hubs provide improved geometry for better steering and traction, fully adjustable axle height and improved driveshaft alignment.

Gear Differential.

The gear differential repositions the pulley for a more centered rear belt alignment that improves consistency and forward traction.

Solid Axle.

New solid axle features updated pulley position to shift the front belt alignment to match the new center layshaft for improved consistency and forward traction.

Spur Gears & Pulleys.

Precision-molded spur gears are made from XRAY’s exclusive composite material, ensuring true running, super-quiet operation, and robustness for handling powerful motors. A range of optional spur gears for fine tuning is available.

Front Shock Tower.

The split aluminum front shock towers are mounted directly to the chassis and have adjustable flex options by adding screws to secure the towers to the bulkheads for additional stiffness.

Rear Shock Tower.

All-new aluminum one-piece rear shock tower is mounted directly to the rear bulkheads and its shape provides optimized shock positions for maximum rear traction. Unlike the split front towers, the one-piece rear tower was found to provide better consistency and balance throughout testing.

Rear Body Mounting System.

Rear body mount system connects directly to the chassis using vertical or horizontal body post positions for improved downforce and traction.

Steering System.

The new steering system has a more responsive and precise feel from the lowered steering plate with more efficient geometry, shorter posts, integrated adjustable steering lock and the included aluminum steering arms.

Servo Mount.

Universal reversible servo mount fits all standard servos without extra parts, with the choice of front or rear position to adjust the chassis flex and steering feel for different conditions.

Drive Shafts.

Longer front ECS and rear CVD drive shafts with new drive axles move the pivot in line with the hub rotation to improve traction and efficiency.

Front Chassis Brace.

The aluminum front chassis brace installs underneath the front solid axle and significantly improves the front chassis stiffness, making the X4 steering more responsive and generating more forward traction.

Front Bulkheads Brace.

Front graphite brace reduces flex in the front of the car and increases stability on bumpy tracks. The upper bumper brace reduces chassis damage in serious crashes.

Shock Springs.

X4 comes with specifically chosen shock spring sets for the best possible performance out of the box.

ULP Shocks.

The ultra-successful and popular ULP shocks from the T4 platform are carried over to the X4.

ULP Shock Parts.

All the parts of the ULP shocks are specifically designed for the lowest possible size to reduce the weight and keep the lowest possible CG.

Servo Saver.

The popular XRAY servo saver that has become the industry-standard saver is included in the X4 kit for precise steering & sufficient flexibility to prevent servo damage in serious crashes.

Battery Holders.

The tweak-free, fully adjustable Quick Battery Mounting System offers simple and secure battery installation without tape and without adverse effects on chassis flex.

Special Hardware.

To ensure maximum performance, the X4’s high-precision pivot balls are machined in-house and then black coated or nickel coated for a smooth and long lasting finish. To maintain proper balance through every run, the in-house machined top deck screws ensure tweak free handling from start to finish.

Drive Belts.

The 2-belt 4WD drivetrain concept provides maximum efficiency featuring 3mm narrow front and rear drive belts that have been specially ground for minimal thickness and maximum flexibility.

Ball-Bearings.

A full set of 25 high-speed, blue-sealed and steel ball-bearings are used throughout the drivetrain, steering and anti-roll bars to ensure maximum efficiency.

Bearing Holders.

Both front and rear bulkheads feature additional integrated belt-tension adjustment through the use of adjustable bearing eccentric holders. These holders are also reversible to move the differential height from the lower or upper position that is now +1mm higher than the T4 platform.

Anti-roll Bars.

The graphite and aluminum versions of the X4 come with specifically chosen anti-roll bars for the best possible performance out of the box.
