1-piece Electronics Assembly
The 1-piece electronics assembly is very compact and can be quickly & easily removed for very comfortable servicing and cleaning. You need only to release only a few screws from the bottom of the chassis to remove the entire electronics assembly from the car.

The large molded radio box features a very clean design and layout that places the weight in key areas for proper balancing. The batteries are placed on the centerline of the chassis and the lightweight receiver is placed on the side. The very easy-to-access radio box is mounted on the side of the radio plate and is releasing by only a few screws.

For racers not using a radio switch, a handy molded cover is included to help guarantee a leak-free radio box. The tight antenna tube holder ensures that the antenna tube stays attached even if the car flips.

The radio box was redesigned to fit to the new chassis and the battery cover was redesigned to hold the batteries better.

Steering System
With the new centralized design concept, the steering stands were narrowed and placed as close to the center as possible using very lightweight aluminum standoffs. The very narrow steering plate is precision-machined from high-grade graphite, thus reducing unnecessary weight. The steering plate features several different Ackermann settings for precision steering setup.

The dual steering system rides on lightly-oiled ball-bearings, providing super-smooth and super-fast steering action. The strong servo saver spring makes sure that steering will be very precise in all conditions, but is still soft enough to ensure that energy will not be transferred to the servo even in heavy crashes. The strength of the servo saver can be easily adjusted through a adjustment collar; the collar is hard-anodized to prevent thread stripping in to dusty conditions.

HUDY Spring Steel™ Steering Turnbuckles
All turnbuckles in the 808 are manufactured from special HUDY Spring Steel™ material for turnbuckles, resulting in stronger turnbuckles with a tougher core. A handy turnbuckle tool is included.

With the narrow steering plate and narrow steering stands, the turnbuckles were properly resized and elongated. The relief steering ball-joints to provide a better fit into the wheels.

Newly-redesigned Big-Bore Shocks
Off-road performance depends very highly on perfectly-working shock absorbers. As such, all components and pieces of the 808 shocks were completely redesigned to obtain the best possible performance: shock bodies; pistons; shock cap; membranes; lower shock collar; rubber boots; internal shape; alu cap; springs.

The most significant improvement is the bore of the shocks, which was increased to allow for a higher volume of oil to flow for improved damping characteristics. The new big-bore shock pistons were designed and manufactured with a special molding process to ensure optimum tolerance and roundness of the pistons so that they move freely and very precisely inside the shock body.

The front and rear shocks can be mounted in multiple positions on the shocktowers and arms; these positions were thoroughly tested and analyzed both in virtual reality as well on the tracks to offer the widest possible range of shock positions. This guarantees sufficient suspension travel and best setup for either flat European-style tracks or large bumpy US-style tracks.

Shock Bodies
The oversized big-bore shocks feature 18.5mm outside diameter shock bodies, externally threaded with an adjustable collar for downstops adjustment. The shock bodies are hardcoated, and features a new 1-piece alu shock cap.

The large 15.3mm inner diameter of the shock bodies ensures proper and consistent shock oil flow through the perfectly-round pistons which move very precisely inside the smoothly-finished interior of the shock body. The result is more consistent damping characteristics of the shocks.

Shock Pistons
The new big-bore pistons are manufactured from well-proven specially-formulated composite material to provide smoother action and durability. The well-proven molding production process is used to ensure perfect roundness of the pistons after production, so that the pistons will move perfectly inside the shock bodies for identical shock action in all four shocks.

Shock Membranes
The new shock membranes are now wider to fit the new big-bore shocks. The material has been also improved to guarantee the same damping characteristics from the beginning of the race to the end even after excessive overloads.

Lower Shock Cap
The lower shock assembly ensures that the shock rod will move very freely inside the shock body but at the same time will minimize oil leakage and keeping the dirt away. Two shock O-rings – manufactured from a superior silicone compound to allow ultra-free movement of the shock rod while still maintaining a tight seal – are installed in the lower part of the shock body and are secured with composite shims. The entire lower shock assembly is secured with the new lower aluminum shock cap which makes assembly/disassembly quick and easy. The aluminum lower cap features an internal protective “dust foam” which keeps the dirt out.

Shock Shafts
The shock shafts are thick and robust to ensure they will handle any abusive racing conditions and big jumps. The 3.5mm thick shock shafts are precisely machined from special high-tensile steel and afterwards are ground for a super-smooth surface to ensure very free and smooth movement of the shock shafts in the shock bodies.

XRAY Premium Silicone Oils
The 808 features the new XRAY Premium Silicone Oils manufactured in Europe by a specialized premium silicone oil manufacturer; these new oils were exclusively created for XRAY. Each batch of premium oil is laboratory tested and calibrated to ensure the highest possible consistency and quality batch-to-batch. Based on the industry-standard cSt rating, the new line of oils will be easy to identify, adjust, and feel.

When following any setup sheets by XRAY or XRAY team drivers, you can be sure that the oils you will get for your car will be exactly same as used by the factory racing team, thus ensuring very exacting setups and handling of the car.

Clutch System
The flywheel is CNC-machined from high-quality Swiss 7075 T6 aluminum. The clutch features three (3) lightweight 1.71g aluminum shoes and a set of hard clutch shoe springs. HUDY Spring Steel™ clutch nut is included, along with necessary shims and hardware. The flywheel brass collar is not included and is available with every engine supplier or optionally from XRAY.

Oversized Clutch Bearings
The 808 clutchbell features unique oversized ball-bearings designed and engineered by XRAY. Replacing the standard 5x10 bearings with balls of only size 1.3 mm, the oversized 808 clutch bearings are 5x12 with balls of size 2.0 mm and with extra-thick bearing walls. This translates to higher load carrying capabilities which will increase the life of the bearings and reduce the risk of clutch bearing failure during long final runs. The bearings come with special high-temperature resistant grease to ensure proper lubrication during high-revving engine operations and long runs.

Engine Mounts
High-grade CNC-machined aluminum engine mounts are machined from lightweight alloy and help to dissipate engine heat. The engine mounts are easily adjustable from the bottom of the chassis to obtain proper gear mesh.

The engine mount is all newly designed, it is longer and goes up to the front engine bearing which provides higher reinforcement of the chassis in the longitudinal direction and in jumps will minimize the bending of the chassis between the clutchbell and spur gear.

Brake System
The XRAY 808 features the well-proven high-performance braking system that is so strong and precise and dependable that is makes slowing and stopping a profoundly exhilarating experience. Coupled with the car’s balanced load distribution, the extraordinary control imparted by the braking system give you complete confidence as you pitch the car into the corner.

XRAY focused on all of the smallest details when designing the brake system. The laser-cut, precision flat-ground ventilated steel brake disk allows fade-free braking in conjunction with the special high-grip Ferodo® brake pads installed on the laser-cut brake plates. The brake disk is small, slim, and very light. The precision hand-grinding allows true, wobble-free rotation. Brake inputs are transferred precisely to the brakes thanks to the rigid high-precision machined brake cams. Both brake disk and brake pads are specially heat-treated for maximum lifespan.

Fuel Tank and Air Filter
The fuel tank with integrated stone filter has a molded-in splashguard to protect the brakes from fuel spillage. The tank is mounted with rubber grommets to absorb vibration. Small composite holders secure thick 5.5mm silicone fuel tubing.

The smooth-flowing and efficient air filter is made from two parts. Air filter oil is included as standard. The universal rubber elbow allows fitment to most standard 1/8 buggy engines.

Anti-roll Bars
Anti-roll bars are included to stabilize the car at both front and rear and the 808 features new shorter anti-roll bars which also have a different angle to accommodate to mounting on the new suspension. The roll bars are easily mounted to the diff cases and can be adjusted through the adjustable linkages.

Both front and rear anti-roll bars have a thickness of 2.4mm. Anti-roll bar wires of different thickness are optionally available for fine-tuning your setup.

Wing
The aerodynamic rear wing is molded from a very flexible yet virtually unbreakable composite mixture. All edges are reinforced at critical areas to prevent cracking or breakage. The rear wing holders are mounted firmly to the rear shock tower. The rear wing holders offer many different wing-mounting positions for increased adjustability at different tracks.

New XRAY Body
The 808 comes with the all-new XRAY lightweight racing body with all-new ultra-flat slick design. The area around the engine was specially redesigned to have the engine head to protrude outside of the body as much as possible to allow maximum cooling of the engine. The sides of the bodies have a tight fit to the sides of the car to minimize the amount of dirt entering the chassis. This also helps in wet conditions.
