Is my idrive a Torsion idrive or TorqueMaster idrive?
A torsion idrive will have internal toothed gears to the left and right of the operator and the counter blance (Torsion springs) will be visible on the tube. A TorqueMaster idrive does not have gears to the left and right of the operator and the counter balance springs are contained within the TorqueMaster tube and will not be visible.
