XRAY GTXE Designer
The GTXE project follows a typical development progress at XRAY: 3D models were first printed & tested, and after successful test results the production moulds were machined. To ensure perfect fitment of all parts, all pieces are individually tested during the development phase and then are tested on track to ensure maximum reliability and performance.
Made in Europe.
Designed, developed, and fully manufactured in-house at the XRAY factory in Slovakia, Europe, using the most high-tech German & Swiss machines and premium European materials, crafted with XRAY’s legendary attention to detail by our artistic production specialists. The GTXE is truly a masterpiece.
The chassis is CNC-machined from 3mm high-quality Swiss 7075 T6 aluminum, strategically machined in low-stress areas, and then anodized to make it as light as possible without affecting strength or rigidity.
The chassis is specially designed for the electric version to allow for the best chassis flex, weight balance, and clean chassis design.
Front and rear chassis braces have significant influence on chassis stiffness and flex, and as such have a great impact on handling under different grip conditions.
The longer rear brace is moulded from a medium-stiff composite mixture for proper flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the brace to make it even stiffer (suitable for high-traction conditions).
The battery plate design allows to move battery more frontwards or rearwards, giving significant influence on weight balance adjustment.
The rear of the plate has a dedicated area for speed controller placement. Velcro® strips are included for quick & easy battery mounting.
Electronics Weight Balance.
The layout of the electronics placement was designed with the attention to the optimum weight distribution and weight balance. During the design and prototyping phase several different layouts were tested and an extensive amount of data was collected, compared and evaluated by the factory team before the final design was chosen.
Weight Balance Adjustment.
Weight balance on the GTXE is easy to adjust for different track conditions. Weight can be moved to the front, middle, or rear by moving the suspension arms as required to achieve the best handling.
Diff bulkheads are an important chassis component, housing both the front and rear differentials and providing mounting points for the suspension mounts and shock towers.
The diff bulkheads have been designed for extreme durability, while providing easy access for tuning and maintenance.
Pivot Ball Suspension.
XPBS™ (XRAY Pivot Ball Suspension) is a uniquely innovative concept and intelligent R&D design. The ultra-robust pivot ball suspension has integrated suspension geometry adjustment, with different kingpin plates being optionally available.
The complete integrated suspension geometry adjustment includes:
Upper & Lower Roll Centers
Suspension geometry is one of the most important features of any RC model car, while still being one of the most difficult & challenging features to design properly.
Suspension is always a mixture of:
Design & shape of individual suspension parts
Flex & hardness
Geometry & position of mounting points of connecting parts
From the suspension arms, through the suspension blocks, to the robust steering blocks… every suspension part has been carefully designed for the 1/8 racing platform to provide responsive racing characteristics in all conditions.
I.S.S.™ Suspension Holders.
The aluminum suspension holders feature Integrated Suspension Settings™ (I.S.S.) which allows for quick & easy suspension geometry setting.
Using eccentric suspension bushings inserted into aluminum suspension holders – as well as additional suspension shims – the GTXE suspension geometry can be completely adjusted in mere seconds.
GTXE suspension arms are the result of long-term testing of different designs and layouts. Length, thickness, flexibility, geometry, and materials used… these are all part of the concepts and details that are thoroughly reviewed to create optimum suspension arms.
The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough for extreme durability. The exclusive composite mixtures used for suspension arms are a perfect balance between reliability and performance.
XPBS™ steering blocks are unique, innovative, smart… an authentic XRAY innovation.
The steering blocks feature the following integrated geometry adjustments:
The steering block consists of a super-lightweight composite steering block and stiff Swiss 7075 T6 kingpin plate. The steering block is mounted via massive pivot balls into the upper & lower suspension arms.
The upper pivot ball is mounted into an adjustable upper ball joint and via roll center shims to the kingpin plate; this assembly allows camber and upper roll center adjustment. Using shims of various thicknesses, the upper roll center can be adjusted quickly & easily.
The lower pivot ball is mounted into the steering block via an adjustable alu nut and composite bushing. By adjusting the pivot ball, both track-width and camber can be adjusted.
A higher roll center (more shims) is recommended for grippy, high-traction tracks as well as bumpy tracks.
A lower roll center (fewer shims) is recommended for slippery & smooth tracks.
The included kingpin plate offers two different mounting possibilities: either 0° or 7°
The ultra-tiny XPBS™ rear uprights are unique, innovative, and smart… pure XRAY.
The rear upright consists of a super-lightweight composite upright block and stiff Swiss 7075 T6 mounting plate.
The upper roll center plate has a unique design that allows easy changing of roll center position. The roll center plate features 2 roll center positions; by reversing the orientation of the plate another 2 roll center positions are available. The roll center adjustment range is 2.5mm. The roll center height of the upper camber link can be adjusted via shims of various thicknesses. The composite upright features 2 lower roll center positions.
The outer suspension pin – on which the rear upright sits – features 2 shims which allow for additional wheelbase adjustment.
The uprights feature integrated geometry adjustments including:
upper & lower roll centers
Front Upper Suspension.
The front upper suspension is part of the innovative, unique XPBS™ suspension concept. Extra-strong, robust front upper arms are mounted to the front bulkhead assembly into the front shock tower and adjustable suspension holder. Using eccentric bushings, front inner upper roll center can be easily adjusted.
Caster is easily adjusted using caster clips which are inserted either in front of or behind the front upper arms.
The ball link is inserted into the upper arm and the integrated adjustable turnbuckle can be accessed from outside for quick & easy camber link adjustment.
To guarantee maximum reliability, all turnbuckles are manufactured from a special blend of HUDY Spring Steel™ which is specifically formulated for turnbuckles. The turnbuckles have a tougher core and are well suited for steering system and rear upright linkages.
The dual-arm steering system is simple yet effective, featuring an integrated, easily-adjustable servo saver and Swiss 7075 T6 aluminum steering plate.
Ackermann can be quickly & easily adjusted by changing steering link mounting positions on the steering plate.
Bump steer is easily adjusted by shims between the steering plate and steering linkages.
The GTXE has a conventional shaft-drive 4WD drivetrain featuring:
front & rear gear differentials with adjustable oil viscosity, 46T crown gears, and 14T pinion gears
central 49T spur gear

The GTXE big-bore shocks have a special construction that offers superior reliability and performance.
The oversized big-bore shocks feature 18.5mm outer diameter shock bodies, externally threaded with an adjustable collar for quick & easy spring preload adjustment. The shock bodies are hardcoated in a titanium color and feature a 1-piece alu shock cap.
Ultra-precise shock pistons feature 6-, 8- and 10-hole options.
The large 16.0mm inner diameter of the shock bodies ensures proper & consistent shock oil flow through the perfectly-round pistons while they travel inside the smoothly-finished interior of the shock body. The result? More consistent damping characteristics.
GTXE springs have been specifically designed to complement the big-bore shocks.
XRAY shock springs are manually measured, selected, and matched into pairs to guarantee precisely equal length and damping characteristics.
Ultra-precise shock pistons feature 6-, 8- and 10-hole options. The big-bore pistons are molded from tough, well-proven Delrin® material for smooth action and durability. The precision molding production process ensures perfect piston roundness after production, so that the pistons move super-smoothly inside the shock bodies for identical, perfect action in all shocks.
The center solid axle is a precision-manufactured, super-smooth layshaft made from tough HUDY shaft steel, which is additionally heat treated for superior strength and long life.
The gear adapter is CNC-machined from Swiss 7075 T6 for super-precise and wobble-free installation of spur gear.
The motor is connected to a mounting plate, with the assembly then inserted into an integrated motor holder/drivetrain support. The design of this system allows quick & easy motor rotation to adjust gear mesh, and then clamping into position to prevent further movement.
The motor mount is machined from Swiss 7075 T6 and is 2mm wider for improved durability.
The receiver box is mounted on the same graphite plate as the servo. The graphite plate is connected to the chassis by an aluminum holder and stand that can be easily removed from chassis for cleaning and maintenance. You need only to remove 3 screws from the bottom of the chassis to remove the servo and receiver box.
