3.75" coil spring OD

Hi I am trying to find out what the Outside diameter of a 3.75" coil spring is.

can anyone help by measuring one of there's?

depends on the wire diameter which depends on lenght and rate...wire diameter has a wide range pending application. They hold the ID so it fits coil hardware, the OD is reference. If your design is that tight...make more room.
