I just took delivery of a fusion 4 x 4 The 60 rear axle I was able to both of my coil overs without binding or issue. I did order the D 60 rockstar Skills to utilize with a new axle but I’m thinking about sending the brackets back. Do you think there are any issues with not using the brackets? I only see this limiting the up travel which I need to do running 40s anyway, and still allowing full extension of the coil over
