Just ordered this. Is it just an easy bolt on? Will I need to do any fabricating to make it work. I have all UMI uppers, lowers, relocation brackets, 3 way shocks, moog cargo springs.

I'm probably one of the first guys here on TC to buy the HR Parts bar years ago.
It's a simple install. You'll only have to drill 4 holes to bolt the uplinks to the frame bracing.
