The XT8 chassis was completely redesigned to allow for updated and completely all-new weight distribution to improve chassis balance and stability.

The chassis is CNC-machined from high-quality Swiss 3mm 7075 T6 aluminum, which is strategically machined in low-stress areas and then anodized to make it as light as possible without affecting strength or rigidity. 

Non-essential material below the engine, fuel tank, and diffs was removed to allow for the lowest possible center of gravity and appropriate chassis flex.

Weight Balance.
The major performance & handling improvement of the XT8 is the all-new weight balance that relocates weight to the front. This improves rotation of the truggy, increases cornering speed, improves handling in jumps, and offers more forgiving handling.

The new weight balance was achieved by completely redesigning the chassis with more weight in the front, and using an all-new, super-short fuel tank.
With the new weight distribution, attention was also focused on side-to-side balance to achieve the desired handling both on the track and in the air.

Fuel Tank.
An all-new fuel tank was designed and produced to make it super short, allowing placement (and weight) towards the front of the truggy. 

Despite its short length, the fuel tank has an extra-large 150cc fuel capacity. The tank is molded from a special composite mixture which ensures very high reliability and rigidity. The molded-in splashguard protects the brakes from fuel spillage. 

An integrated floating stone filter ensures that the fuel pickup will always be in the correct orientation, even if your truggy isn't. This fuel pickup system will allow fuel to continue to flow to your engine, even if the truggy is inverted and waiting to be righted. 

Rubber mounting grommets absorb vibration, and composite holders secure thick 5.5mm silicone fuel tubing.

Side Guards.
The all-new design of the side guards incorporates a larger bottom radius to make the truggy more stable on rough tracks, while increasing longitudinal flex. The side guards are moulded from all-new composite mixture for increased flex which helps to generate more traction.

The tough composite side guards protect the truggy, muffler, and fuel tank from side impacts. The side guards perfectly fit the chassis and seal against dirt.

I.S.S.™ Suspension Holders.
The all-new redesigned and improved aluminum suspension holders feature Integrated Suspension Settings (I.S.S.™) which allows for super-fast & easy suspension geometry adjustment. 

Using eccentric suspension bushings inserted into aluminum suspension blocks – as well as suspension shims – the XT8 suspension geometry can be completely adjusted: 
• Caster
• Camber
• Front & rear toe
• Front & rear roll center
• Front kick-up
• Rear anti-squat
• Wheelbase
• Track-width

A complete set of various eccentric bushings is included for complete suspension geometry adjustment. The bushings are inserted into aluminum holders which are machined from premium Swiss 7075 T6.

Suspension Concept.
Proper suspension geometry is one of the most important features of any RC model car, while at the same time is also one of the most difficult & challenging features for a designer. 

Suspension is always a mixture of:
• design & shape of individual suspension parts
• flexibility & hardness
• materials used
• mounting system
• geometry & position of mounting points of connecting parts

From suspension arms, through suspension blocks, to the lightweight yet robust steering blocks… every suspension part has been specially designed for 1/8 truggy racing to provide responsive racing characteristics in all racing conditions.

Over many years, XRAY has successfully gained and utilized extensive knowledge of suspension geometry and stiffness, which has been applied while designing the suspension parts. The ultra-lightweight suspension parts are molded from a special composite material which makes the parts very light yet very durable to withstand the rigors of high-performance racing.

Suspension Arms.
All-new front & rear lower suspension arms have a reinforced design which makes them more resilient in jumps and crashes. All-new outer pivot pins feature self-locking nuts for increased reliability. 

All suspension parts on the XT8 were purposefully designed & developed for truggy racing. The super-long arms provide maximum stability while the optimum stiffness of all suspension parts ensures maximum traction under all different racing conditions. The super-long suspension arms ensure the best handling over rough terrain and excellent landings from big jumps. 

The exclusive composite mixture used for suspension arms is a perfect balance between reliability and performance. The suspension arm itself is rigid enough to provide a responsive feel, yet soft enough to survive extra-long main events.

Caster Blocks.
The unique C-hub suspension on the XT8 features Integrated Adjustable CasterTM which enables adjustment of the single C-block through the entire caster angle range; no optional caster blocks needed!

The C-block features an inclined kingpin design for increased steering and stability. 

The C-hub suspension includes now steel caster bushings and ball mounts instead of composite versions, giving increased strength & reliability.

Steering System.
The dual-arm steering system was redesigned to increase the reliability and improve the steering characteristics. 

An all-new molded graphite servo saver makes the steering more resilient & efficient in dusty conditions. The all-new alu steering plate gives more aggressive steering characteristics, the all-new composite upper top deck adds flex to help steering, and the all-new steering pivot balls feature backstops for increased reliability. 

Ackermann can be adjusted quickly & easily by changing steering link mounting positions on the steering plate. 

Bump steer is easily adjusted by inserting shims between the graphite steering plate and steering linkage.

Chassis Braces.
All-new front & rear chassis braces have a significant influence on chassis stiffness and flex, and as such have great impact on handling under different grip conditions.

The new front chassis brace adds more front flex for improved steering characteristics.

The all-new rear double composite braces have a direct mounting to the rear bulkhead instead to the rear shock tower. This bulkhead mounting eliminates transfer of vibrations and energy from the suspension via shock towers, helping to improve landings and generating more off-power traction. 

The rear medium brace is mounted with a graphite chassis extension for flex adjustment in 3 different settings. The rear brace is moulded from a medium-stiff composite mixture for better flex & rigidity, and allows the mounting of optional graphite inserts to reinforce the chassis brace to make it even stiffer (suitable for high-traction conditions).

Diff Bulkheads.
The all-new diff bulkheads are reinforced and strengthened for increased reliability. The bulkheads are an important chassis component, housing both the front & rear differentials and providing mounting points for the suspension mounts and shock towers.

The super-strong front & rear bulkheads can withstand rigorous impacts and other abuse during racing conditions. The bulkheads have minimized ball-bearing play, resulting in increased gear teeth lifespan and minimized gear stripping.
