ProTek’s PTK-7618 Ride-Height Gauge Is a Setup Tool, Not a Setup Answer
The new rechargeable digital gauge is specified for 1/24 to 1/8 RC cars, with a 2–38 mm range and 0.1 mm stated accuracy. For drift use, the value is in repeatable measuring, not in replacing track-side judgment.

If your ride-height changes are becoming guesswork, the useful part of ProTek RC’s announced Digital Ride Height Gauge is its measuring window: 2 to 38 mm, with stated 0.1 mm accuracy. That range covers the ride-height numbers normally discussed around small-scale and 1/10 RC chassis, while still extending high enough for other RC categories named in the report.
The announcement was reported by ラジコンもんちぃ, which says the rechargeable gauge, model PTK-7618, is intended for 1/24 to 1/8 scale on-road, off-road and drift machines. The report does not give a price or availability, and it does not describe a drift-car test on carpet, P-tile, concrete or asphalt.
That matters because ride height is not a universal number. On a 1/10 RWD drift chassis, the height you choose only makes sense with the rest of the car: tire specified by the track, surface, spring and damper package, droop, battery position, motor position and the way the body clears the floor and arches. The gauge only tells you where the chassis sits; it does not tell you whether that number is correct for your layout.
Specification
What the report confirms
The confirmed specification is compact:
| Item | Reported detail |
|---|---|
| Product | ProTek RC Digital Ride Height Gauge |
| Model | PTK-7618 |
| Power | Rechargeable |
| Scale range | 1/24 to 1/8 scale RC cars |
| Categories named | On-road, off-road and drift machines |
| Measuring range | 2–38 mm |
| Stated accuracy | 0.1 mm |
| Blade thickness | 2 mm |
| Display | High-contrast display, rotatable 180 degrees |
The 2 mm blade is the mechanical detail worth noting for drift chassis work. A thin blade can reach under areas where a wider block or caliper jaw may be awkward, while the source says the blade is intended to reduce flex in tight measuring locations.
The display rotation is a bench-use detail rather than a chassis-setting theory. If the car is facing away from you, or if the gauge has to approach from the opposite side of the chassis, rotating the display 180 degrees should make the reading easier to see without moving the car.
Drift context
Where it fits in a drift setup workflow
For 1/10 RWD drift, ride height is usually adjusted to solve a specific symptom rather than to chase a number on its own.
A front end that drags over a track seam, clips a body shell under steering angle or feels inconsistent after a spring change can send you back to the setup board. A rear end that sits too low after moving weight rearward, changing battery position or changing motor layout can do the same. In those cases, a ride-height gauge helps separate the actual chassis attitude from what the body makes you think you are seeing.
The source does not provide a ProTek-recommended drift ride height, tire compound, surface or chassis example. So the safe use case is documentation: record the number that worked on your car, on that surface, with that tire. If the track changes from carpet to P-tile, or from indoor tile to outdoor asphalt, treat the measurement as part of a full surface setup, not as a portable magic number.
Bounded call
Who this serves
The PTK-7618 looks most useful for drivers and builders who already make deliberate ride-height changes and want those changes recorded in small increments. That includes 1/10 drift drivers comparing left-right balance after suspension work, Mini-Z or other 1/24–1/28 small-scale drivers who need a low measuring range, and multi-category RC builders who want one gauge to cover several chassis sizes.
It is less urgent if your setup process is still at the stage of getting the car assembled straight, matching the track’s spec tire and setting basic steering and gyro behavior. Ride height matters, but the gauge measures only one part of the chassis. Use it to make a decision repeatable; do not let it make the decision for you.
