They fasten to the tunnel and the original cat drop bracket. They lower the rear skid 1.250" down. No there not sled Junkies. They are quite the piece of work. Billet Aluminum milled out to fit the contour of the OEM bracket. If you look on the HRP website i believe they are shown. I believe they will fit from 03 to 06 King cat.
Anyone need some titanium rear springs??
