XRAY X8'26 Chassis

Name: XRAY X8'26
Brand: XRAY
SKU: 340501

1/8 scale · 4WD touring and drift body chassis kit · 340501

XRAY's X8'26 is a four-wheel-drive 1/8 electric pan car kit, sold without motor, electronics, wheels or tires.

The 53T spur sits on the rear axle, so there is no further reduction and the final drive is simply the spur divided by your pinion. A belt from the rear axle drives the front one-way axle, and the rear pulley size is matched to the front and rear tire sizes. Check the front and rear tire sizes against the setup sheet before you change the rear pulley.

Transmission & axle: 1.00:1
Spur: 53T
Introduced: 2025

Sold without a motor, so there is no stock KV: compare gearing by rollout.

Specifications

Spec	Value	Basis
Vehicle
Class The kind of vehicle the maker sells it as. It sets what the car is built to do and which cars it is fair to compare it with. Touring cars are 4WD on-road cars for asphalt and carpet tracks, often raced in classes with fixed motor and battery rules. The maker does not name a class for this one, so this is the site's judgment from its design. Drive All four wheels are driven, which puts power down more evenly and keeps the car steadier accelerating out of corners. The cost is more parts to maintain. Power Sold without a motor, so you choose the motor, ESC and battery yourself. Rows that depend on the motor say so. Build A kit you build yourself from parts. Most kits come without motor, ESC, servo, radio and battery, and many without tires or a painted body. The manual lists what to add. Scale The maker's nominal size compared with a full-size vehicle. It works more as a class label than a measurement. A 1/10 monster truck is far bigger than a 1/10 touring car, so compare length and weight for real size. Part number The maker's product number for this exact version. A V2, a new color, or a kit instead of an RTR usually has a different number, and parts can differ between them. Check it against your box or receipt before ordering parts.

Drivetrain
Pinion The small gear on the motor shaft. Fewer teeth gear the car shorter: quicker acceleration, lower top speed and a cooler motor. More teeth do the opposite. On a chassis sold as kits, each kit brings its own. Spur The large gear the pinion drives. A bigger spur with the same pinion gears the car shorter. Pinion and spur must have the same pitch, or tooth size, to mesh. The Gearing parts table below shows this car's pitch and part numbers. Transmission & axle Every reduction after the spur, multiplied together: transmission, differentials and axle gears. It is fixed by the design; the gearing you change is the pinion and spur. Final drive How many times the motor turns for one turn of the wheels. A higher number is shorter gearing: more acceleration and pulling power, less top speed. On-road racers often compare gearing by rollout instead, because tire sizes differ between cars.

Wheels & tires
Tire diameter The outside diameter of the mounted tire, tread to tread. A taller tire covers more ground each turn, which gears the car taller. Race tires wear down over a day, and a smaller tire gears the car shorter.

Power
Motor Motor KV is the RPM a motor turns per volt with no load. This vehicle comes without a motor, so there is no stock KV; it depends on the one you fit. Motor shaft The diameter of the motor's output shaft, which a pinion's bore must match. This vehicle comes without a motor, so it depends on the one you fit. Battery The highest LiPo cell count the maker rates the electronics for. This vehicle comes without electronics, so it depends on the ESC and motor you fit.

Performance
Theoretical top speed It needs a motor KV, and this vehicle comes without a motor. Fit one and the calculator works it out from the motor's KV and the gearing.

How to read these figures

Stock is as the vehicle ships.
Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart.
Not applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor.

About teeth, pitch and bore

Tooth counts are the ones in the specifications above.
Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close.
Bore is the pinion’s hole, listed separately from the motor shaft.

How these numbers were settled

Electric 1/8 pan car kit: the manual lists the motor, pinion, speed controller, battery, wheels and tires as not included, so there is no stock pinion or total and the tire size is left blank.

The manual marks the 53T composite spur (#335553) as included, and its rear transmission step mounts it on the rear solid axle shaft beside the 35T aluminium rear belt pulley (#345935).
With the spur on the axle there is no reduction after it, which matches the manual's formula 'Final Drive Ratio (Spur) (Pinion) 60 : X = FDR'; the final drive is the spur over the pinion.
The belt runs from the 35T rear pulley to a 32T pulley on the front one-way axle (#345932), and the setup sheet matches 34T, 35T or 36T rear pulleys to the front and rear tire diameters.
