What is ZRF technology?
The zero rod force shock eliminates rod force caused by gas pressure pushing on the rod end inside the shock. By using a thru rod design, rod force is eliminated.
What is rod force?
In a mono-tube shock, cavitation is prevented by running nitrogen to raise the pressure. This is much like using a pressurized cap on your radiator. The gas pressure pushes on the end of the shock shaft that is in the pressurized oil. The other end of the shock shaft is being pushed on by normal atmospheric pressure (14.7psi). The amount of pressure in the oil multiplied by the area of the shock shaft creates the rod force.
In many cases, rod force itself really makes no difference. BUT, in situations with low grip surfaces, many drivers do not like the "feel" that the rod force causes. In these cases, many drivers are willing to put up with the disadvantages of twin-tube shocks for the forgiving feel they provide. The real problem with rod force in a conventional mono-tube shock is that it varies as the shock moves through it's stroke and as the temperature changes. ZRF technology eliminates this variable, because if there is no rod force, there is no variable.
A thru rod shock is stiffer than a non thru shock because?
The thru rod shock adds stiffness which takes load off the piston band. This added stiffness decreases seal drag. Especially when mounted at an angle which side-loads the shock.
Are there other advantages?
Yes! There is:
So, if you like the feel of traditional twin-tube shocks, this is for you. ZRF shocks will give you the same feel as a twin-tube shock but with the consistency and user re-buildability of a mono-tube.
