This is the perfect ride height gauge for 1/10 nitro and electric cars with a minimum ride height of 3mm. This ride height gauge measures the chassis ride height from 3mm – 15mm. It is constructed from high grade aluminum, anodized gray and an adjustable knob for quick and accurate measurements. Set the vehicle on a flat surface, set the gauge next to it and adjust the tip of the gauge under the front or rear of the chassis, tighten up the knob and you will see your ride height.
