This is a complete set of Oil Control Ring Springs for a 2-rotor motor from 1974 through 2012. We package the OEM front/inner, front/outer, rear/inner and rear/outer springs together (one pair each) to simplify ordering. Those springs with white paint face towards the front of the engine and those with blue paint face the rear. There are larger and smaller diameter springs to fit the outer and inner Oil Control Rings. That is a combination of 4 distinct springs and you need two of each. This package contains them all.
