Xray X12’21 1/12th scale chassis

Based on the ultra-successful X12 platform, Xray presents the all-new X12. Incorporating the latest improvements and refinements gathered by the team, race-proven in high-competition races around the world, and ready out-of-the-box to take you to the Winners’ Circle. The X12’21 is offered in two versions again this year, whether on low to medium-grip tracks which are typical in Europe, or on super-high grip tracks which are typical in the US, there is an X12 to fit each occasion. This completely new platform has 90% new components with the main focus on improvement of durability, stability and traction. A tweak free design, there is a new rear centre pivot mounting system, bulkheads, pod plates & redesigned front suspension.

The aluminium chassis and rear POD have a completely all-new design and shape. The chassis was redesigned to accommodate the all-new front Tweak-Free Suspension and the all-new rear Tweak-Free POD System. The side link mounting system was redesigned as well and is mounted directly to the chassis and the chassis features new slots for adjustment of the servo mount position. The chassis and rear POD edges are beveled, for less resistance to the ground during cornering.

Both EU and US Edition kits include an aluminium chassis as stock equipment this year. The EU version includes the flex alu chassis with more cut-outs better suited for low to medium grip conditions. The US version includes solid alu version, which has less cut-outs, for minimal flex making the car more stable and predictable in higher traction situations. An optional 2.5mm graphite chassis is available as an additional tuning choice, and is a good option for low grip carpet racing, as well as asphalt.

Rear POD

The rear of the X12 has been completely redesigned and features the all-new Tweak-Free POD Mounting System. The all-new POD parts include new aluminium bulkheads and new graphite upper and lower alu pod plates. The new mounting system improves traction and stability of the car and eliminates tweak issues after crashes.

The all-new graphite upper plate was redesigned to mount to the bulkheads with centering pins and 4 screws to secure the assembly in proper alignment and to minimise the chances of tweak after an impact on the track. The rear POD also features completely redesigned one-piece bulkheads to achieve maximum durability. The new bulkheads allow for rear axle height adjustment via traditional eccentric bushings.

POD Mounting System

All-new aluminium Tweak-Free Pod Mounting System improves traction and stability of the car and eliminates tweak issues after crashes. The new system allows for a significantly lowered roll centre, lowered centre of gravity, and pivot height adjustment using different shims. The all-new pod mounting position choices include the standard rearward mounting position where the centre pivot is located in-line with the side link pivot balls on the rear pod plate, and the new forward location that places the pivot 2mm forward of the link mounting points.


The all-new bulkheads are a 1-piece tweak-free design which is more rigid and robust. The new lower profile of the bulkheads and redesigned upper plate help to reduce the overall CG of the assembly. The new bulkheads feature centering pins on the top and bottom surfaces that align the upper and lower pod plates during assembly and prevent movement between the components during a crash. To further enhance the assembly’s strength and resistance to tweak, the upper pod plate now uses 4 mounting screws to secure it to the bulkheads. The 1 piece bulkheads in the X12’21 utilise eccentric bushing inserts for the rear axle height adjustment.

Rear Axle

To significantly reduce the rotating mass and improve steering, both EU & US Editions include a super-lightweight graphite rear axle. The US Edition includes a solid axle for high grip levels. The EU Edition includes a race proven ball differential; better suited for low to medium grip situations.

Tweak-Free Front Suspension

The all-new Tweak-Free Front Suspension was completely redesigned to achieve maximum durability, stability and to remove tweak issues after a crash. The new front suspension design features fewer components, reducing the mass of components mounted high above the chassis plate in previous designs, resulting in a lower CG. A single Tweak-free lower graphite arm that replaces previous composite arms for maximum rigidity are part of the front suspension flex adjustment. New steering blocks feature updated Ackermann positions offer improved steering characteristics. The Tweak Free Front Suspension features the heavy-duty 4mm kingpin system that retains its geometry after an impact to help complete a race without any adverse effects on handling. All-new big bore front springs with larger diameter allows for a smoother and more precise front suspension dampening.

Steering Block

All-new steering block is redesigned to work with the new 4mm king pin axle, features new Ackerman positions for improved steering, and is moulded from a special graphite composite material for minimum friction against the kingpin. The steering blocks use ultra-precise wheel axles CNC-machined from premium HUDY Spring Steel™ that are additionally hardened and hand ground for precision fitment. The 4mm adjustable steering turnbuckles are manufactured from lightweight aluminium.


All-new super-smooth, hardened steel 4mm kingpins provide the foundation for the Tweak Free Front Suspension. The kingpins have a new, stronger design with a machined 1.5° camber angle machined into the kingpin for precise suspension geometry. Optional 1.0° and 2.0° camber king-pins are available to adjust the camber in fixed steps.

Side Braces

All-new graphite side braces are mounted to the rear brace, and to the chassis via aluminium posts, and offer three flex setting alternatives to adjust the chassis characteristics for different track conditions.

Shock Absorber

The centre shock has new geometry with the mounting point moved further back for quicker direction change, as well as improved on-power steering. The shock features a new stiffer spring for improved steering and response. The fully-adjustable shock features an aluminium shock body that is hard-anodised for ultra durability. The fine-threaded shock body allows for quick and easy shock spring preload adjustment. Tiny, thin shock membrane gives smooth dampening characteristics, and a super-soft silicone shock O-ring gives super-smooth operation while preventing oil leakage. The ultra-finely finished shock shaft with precision moulded composite shock piston ensures optimum shock oil flow and smooth shock absorber action.

Servo Holders

All-new ultra-low CG servo mounting system places the servo directly on the chassis to improve the steering response, and with adjustable grooves in the chassis to place both small and micro size servos into the absolute centre of the chassis. The servo holders feature an additional hole to fit micro servos such as Sanwa SRG-HR, HS and PGS-HR, while the standard positions still accommodate the standard 1/12 servo dimensions.

Servo Position

Unique & innovative fully-adjustable servo mount allows easy adjustment of the servo position. The servo is attached to independent mounts that are mounted using a groove in the chassis. Depending on the size of your servo, you can easily install and adjust the servo and its position to the centre of the chassis.

Side Link Mounting System

The all-new X12’21 mounts the side links directly to the chassis for better consistency, rigidity, and a lower CG. The chassis retains the two choices for the front pivot location, with the inner mounting position offering more on-power steering.

Rear Link Brace

The rear link brace was redesigned to accommodate the new side braces and is part of the Multi-Flex setting. The rear link brace allows for a wider range of battery placement adjustment as well as featuring the convenient O-ring battery mounting system. The graphite rear link brace holds the side tubes as well as the side springs and body posts. It also functions as a backstop for the battery pack.

Rear Ride Height

The alu bulkheads allow for very quick & easy ride height adjustment using eccentric axle holder bushings. The axle height is adjustable in 1/2mm increments over a 5mm range. Smart & easy.

Bumper Holder

All-new front bumper design and new size to meet new racing organisation rules. Machined from premium 2.5mm graphite, the brace is flexible yet rigid enough to withstand serious crashes.
