The current version of the NARAKU counter-pressure spring uses a modified alloy of the spring steel and has a special identification of the spring type.
A change becomes necessary as soon as a tuning measure increases the performance. Remarkable due to slipping V-belts or non-rotating motors.
The backpressure spring is always closely related to the variomatic.
If another spring is mounted, this affects the switching behavior of the variator.
In contrast to other manufacturers, the speed shift is indicated on the NARAKU springs,
in which the variomatic is connected when the rollers are not changed in the vario.
This allows a much more precise selection of the correct spring than a percentage.
A 1500 spring will allow the Vario to change its transmission ratio about 1,500 rpm later
