If your 4115's headlights are set up like my 4100's, and I think they are, you'll want a D51 not a D51R. I ordered a D51R mistakenly and the posts hit the headlight housing account of them being too far forward. If you get the D51 and turn it so the positive post is on the right, as you face the battery, the posts will be towards the radiator screen and will clear the headlight housing.
