The examples of shock absorber mounting shown illustrate a typical application that can be used to aid in sizing the shock absorber unit to a system. It is recommended that the system should be designed at 60% of the units rated capacity. This allows the best adjustment control (mid range of adjustment).CAUTION: Exceeding the published maximum energy, angle of travel or using either end of the unit’s travel as a positive stop for the system VOIDS the warranty of the unit.
