" This is a brand new widening kit for 2005 Fusions & 2005 RMKs, comes with all parts necessary, upper and lower a-arms, spindles, sway bar, and tie rods. Also all these parts are the same pieces on the 05 900 Fusion."
The above quote is from the E-Bay auction on the "widening" kit. Seems to me that these are stock 05 Fusion 900 front suspension parts............

If installed on an
RMK, they would then widen the front end. Installed on a Fusion, you end up with the same ski width......
