At increase in load of back wheels deformation of a spring of a back suspension bracket are deformed, a back part of a body falls and the road gleam decreases. The stabilization device automatically supports a road gleam at the set level. The back suspension bracket is stabilized on the run of the car.

The stable road gleam improves stability of the movement and smoothness of the course.

The road gleam is stabilized at increase in load of back wheels approximately on 140–300 kg.

Stabilization of a road gleam in a zone of a back suspension bracket is impossible if the mass of freight is too small or exceeds 300 kg,

That the road gleam came back to the set level, it is necessary to pass distance of 4-5 km in city conditions or 8–10 km on the highway. However, the specified distances can change depending on freight and its arrangement.

The road gleam will increase after unloading of the car. After the car passes distance of 0,4-0,5 km, the road gleam will return on the set level.
