I'd like to jump in on this RUF discussion (as old a post as this may be) with a question as I'm setting mine up now on a build. I'll post the question again in my build thread once I get photo privileges. Sorry I can't put pics up yet... I'm setting up the front hanger (currently tacked in place) with eyelets located at leading edge of the frame. It's on an 86 Runner after stripping the IFS so I have no guide or reference as to where a stock hanger would be but I think I'm 1-2" forward. I have Sky Boomerangs on the rear of the spring that are negative enough with no load to be 1/2" from hitting the FRONT of the body mount support. I went with boomerangs to avoid hitting the REAR of the body mount support. My plan is to load the frame back up with drivetrain and body while still tacked to get an idea where the shackle angle will sit. My hope is someone else has set their RUF up on rails as I am doing that can make me feel a little more comfortable with this negative shackle angle. I'm pretty sure the boomerangs will address the compression hits but now I'm concerned I'll have a just positive shackle angle once loaded and hit mount on droop.
Any thoughts?
