XT2 Concept

The XT2 is distinctively XRAY – a premium, professional, high-competition R/C stadium truck for the most demanding of racers; developed with attention to the smallest details and backed by leading service & support…a luxury masterpiece.

Uni-Platform™

The XT2 platform works at the highest competition level in any track condition.

Whether it be super-low-traction dusty tracks, medium-traction, super-high-traction carpet or astro turf; there is a XT2 that will handle flawlessly for you in any condition.

The XT2 is available in two different editions – Carpet or Dirt; each specifically built for particular track conditions. Both editions are built on the same platform with full compatibility and interchangeable parts and the XT2 also shares many components with the XB2.

Chassis

A completely redesigned 2.5mm one-piece chassis with a wider rear section improves traction and stability on all surfaces.

The wider rear geometry enhances flex characteristics, resulting in more consistent handling and improved overall balance.

The chassis plate is CNC-machined from high-quality 2.5mm Swiss 7075 T6 aluminum to maximize stability, durability, and drivability while helping to lower the center of gravity.

The centerline cut-out is now connected to the electronics plate milling, allowing the sensor cable to be routed underneath the battery for a cleaner electronics installation.

Additional milling in strategic areas refines the flex characteristics and improves handling response, allowing the chassis to deliver more precise and consistent performance.

Flat Chassis Brace

The bottom aluminum Flat Chassis Brace is an all-new concept carried over from the popular XB2 platform, where it has proven highly successful and now adopted on the XT2.
This innovative system allows the chassis flex to be easily adjusted to match the traction level of any track condition.

This brace is mounted directly onto the chassis and is connected with the rear gearbox and C suspension holder.

The Flat Chassis Brace is significantly lower, lighter, and allows for extremely simple yet powerful flex adjustments.

The flex of the brace is adjustable by adding or removing screws to create the perfect flex characteristics for any conditions.

Side Braces

Redesigned longer side braces match the new chassis design.  The longer braces extend the longitudinal chassis flex control to improve consistency on the track.
The left side brace also allows for a fan to be mounted directly to the brace for enhanced motor cooling.

The side braces support the one-piece chassis design and connect with the front end. The flex of the side braces was optimized to improve front stability & rear traction. The braces feature several mounting holes for the battery holders to provide sufficient range of battery position choices.

The side braces are available in two different hardness alternatives. Both Dirt and Carpet edition comes with medium stiffness and optional Graphite braces are suggested for extra high traction conditions.

Suspension Holders

New design of the rear-front RF suspension holder (C) integrates with the Flat Chassis Brace to create a solid assembly for increased stability.
The rear-rear RR (D) suspension holder geometry creates 3.0 degrees of inboard rear toe for stability in all track conditions, and increased suspension support both in and out of the corner.

The aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) for quick & easy suspension geometry set-up.

Machined from premium Swiss 7075 T6 aluminum and black coated.

The suspension holders are universal for both Dirt and Carpet editions.

3G Gearbox

Updated 3G Gearbox integrates with the lower Flat Chassis Brace. The weight bias of the 3G transmission creates a balance between steering and stability that is well suited for a wide variety of track conditions on dirt, clay, turf or carpet.

The 3G Gearbox is included in both XT2C and XT2D, with the universal design allowing easy & fast changes between 3G and optional 5G without changing the chassis.

Super-narrow, ultra-low CG gearboxes (LCG) features quick & easy diff access. The narrower design of the gearbox reduces weight and moves all parts closer to the chassis centerline.

Gear Differential

The Gear diff in the Carpet edition was redesigned to allow for unified drive shafts length for the Ball Diff and Gear Diff alternatives. The diff case, diff cover and diff outdrives were updated.

The gear diff comes now with steel satellite gears for improved efficiency and increased lifespan.

The gear differential is suggested for medium to high traction conditions as it increases on-power steering and is beneficial on all carpet tracks.

Motor Mount

Redesigned and unified motor mount for 3G Gearbox takes advantage of the additional chassis clearance and lowers the motor position for lower CG.

The super lightweight motor mounts are machined from Swiss 7075 T6.

The molded composite gear protector prevents contact between the spur gear and the body. Moulded from strong, lightweight material, the cover helps to protect the body shell and spur gear, and it allows the body to be mounted lower without interference.

Rear Roll Center Holder

New aluminum Rear Roll Center Holder is included in both Carpet & Dirt kit. Its centering milled area for the anti-roll bar collar eliminates play and improves the precision of the anti-roll bar movement.

The new holder also adds an extra middle pivot ball mounting position for additional roll center tuning. The aluminum holder increases strength & reliability over the previous composite part.

Suspension Arms

The solid front and rear suspension arms accommodate the anti-roll bar system and are molded from medium hardness mixture suitable for all standard track conditions.

The rear arms feature two additional mounting holes to match the updated new shock tower geometry.The solid arm design provides a responsive feel while maintaining enough compliance for extreme durability.

The exclusive composite mixtures used for the suspension arms offer the perfect balance between reliability and performance.

Heavy Duty Turnbuckles

All-new 3.5mm Heavy Duty Turnbuckles together with the new 5.8mm Heavy Duty Ball Joints and Ball Ends ensure super strong and more reliable steering & camber links. The new composite ball joint design reduces bind for smooth suspension and steering movement.

The ball joints increased to 5.4mm instead of the previous 4.9mm. There are two different ball joint shapes: one straight and one curved for improved clearance around the front spring and wheel. The ball joints are slightly longer so the turnbuckle thread deeper in the ball joint to improve reliability and prevent deformation of the plastic at the weakest point at the end of the turnbuckle thread.

The steel turnbuckles increased from 3.0mm to 3.5mm to increase durability.

The new 5.4mm ball ends’ height was increased by 1.0mm to improve the range of motion of the joint. The complete 5.4mm assembly is smoother and more reliable.

Shock Towers

Front and rear carbon shock towers are updated with lower geometry. Lowering the shocks increases stability, cornering speed and makes the handling feel more precise. Thanks to the chassis design, the car’s traction has improved, and the lower shocks help to further improve the handling of the car.

Both front & rear shock towers compliment the big bore shocks.

The extra strong front shock tower is mounted forward for the needed clearance to install the shocks behind the tower for maximum protection in a crash.

Front & rear shock towers are machined from premium-grade carbon material that is lightweight & strong, with multiple shock adjustment positions.

Big Bore Shocks

The big bore 13.2mm shock absorber length was shortened to provide proper suspension travel with the new shock tower geometry. The shock body and shock shaft were shortened to produce the necessary compression and extension range of motion.

The big-bore 13.2mm shocks improve handling, landing, and bump absorption. The X-rings provide smooth operation & dust resistance. Two different piston thicknesses are included in the kit for tuning along with piston blanks for additional tuning possibilities.

The shock absorbers are universal for both Dirt and Carpet edition.

Shock Adjustments

The XT2C & XT2D feature a -2mm lower shock spring collar for front and -4mm for rear to reach lower ride height settings needed on smooth high traction surfaces. The ball joints are in both kits +2mm for perfect balance between droop and upstop travel.

Shock Springs

2-dot front and rear springs are now included in both Carpet & Dirt kits to improve out-of-the-box performance on most tracks.
The shorter springs match the new lowered shock tower geometry while maintaining proper suspension function.

A range of shorter springs in multiple hardness options is available for precise fine tuning to suit different track conditions.

Body & Wing

The updated body for the XT2C & XT2D is redesigned to match the shorter shocks and lower shock tower geometry.

This allowed the body to be mounted lower on the chassis, resulting in a lower center of gravity and improved driving dynamics.

To accommodate the lower body position, the mounting points were revised, and both the front and rear sections, along with the trimming lines, were updated for a precise fit.

The high-performance, low-profile aerodynamic body was designed by XRAY to perfectly fit the XT2 and work in most track conditions. The body is made from high-quality, premium Lexan™ material.

The effective rear wing was designed to work perfectly with the XRAY XT2 body. Made from strong Lexan™ material; the wing is supported on the wing mounts by extra flat shims to better support and extend the life of the wing.

Anti-roll Bars

The front anti-roll bar mounting plate is molded from a soft composite material for increased reliability and perfect integration with the front upper deck.The anti-roll bar system improves cornering performance and makes the XT2 easier to control and more consistent across all track conditions.

The kit comes with 1.6mm anti-roll bar, optional anti-roll bars for fine tuning are available.

Battery Holder

The redesigned side braces allow mounting the battery holders in an extra forward position to move the battery weight as far forward as possible. This additional weight balance alternative expands the weight balance adjustment range to help achieve the best performance on any track condition.

Tweak-free fully adjustable battery holder is integrated into the side guards allowing easy and fast battery position adjustments, as well as simple battery installation through the smart quick-release system.

The battery pack can be easily moved front/rear to adjust the balance of the car.

The height of the battery backstop is adjustable for different battery sizes.

The battery holder is mounted to the chassis through one connecting screw on each side brace to eliminate any effect on chassis flex. 

Extra forward battery position to move weight as far forward as possible.

Front End

The front end of the XT2 was specifically designed to be unified for both Carpet & Dirt versions.

Front Upper Deck

Bridge style upper deck helps to optimize flex from side to side and front to rear while also providing clearance for the steering system. The upper allows mounting the shock absorbers behind the shock tower for better protection in a crash

Steering System

Steering arms, Ackermann plate and the servo arm were reconfigured for more precise steering feel. Thanks to the upper deck design, the steering system also has more space to achieve the improved steering performance. To integrate with the one-piece chassis, the steering post was updated as well.

Steering Blocks

To improve the reliability and strength, the steering blocks are molded from a medium hardness composite mixture that is suitable for most track conditions. The medium compound significantly improves the reliability to enable finishing a race after significant crashes or impacts.

Both Carpet and Dirt editions now feature 3 dot steering block extensions better suited for all track conditions. These extensions create a more linear steering that improves control in all conditions.

There are four different steering blocks available – medium (included), hard (option), graphite (option) and aluminum (option) – which can be used to fine tune steering response for various track conditions.
