yes i made the brackets, not sure if your sp has coolers underneath the boards or not. But if it does yours will look like mine. I dropped it just below the coolers. And yes it's a 136, i wanted to go 144 but a buddy was parting out a sled and gave me everything i needed. 144 would be awesome. good luckadam.rairden said:Im guessing thats a 136"? Where did you get your drop brackets from? Or did you make them? I have a 97 ultra sp im currently putting a 144" on it and im going to drop the suspension some, but not quite as much as your though.
