Please report back with your opinions on the 5100s and the sway bars. I just installed the front and rear sway bars on mine and noticed that my rear shocks are leaking again. I'm debating between pulling the trigger on the 5100s or having Ford replace them a second time. As I understand it, the 5100s are a bit stiffer which should help with the bobblehead effect. I'm wondering if those plus the bars are too much.
Just got the Bar installed and dropped off the kids at the pool, it was noticeably better in the hard cornering (round about & 110degree off camber right hand turn)
The 5100s are stiffer but not that bad, i also upped my tires to E rated LT and larger 275/60/R20...and left the sumo spring on. It is the best it will be for towing my 8k+ travel trailer.
Little bit of road rumble from the tires, a little bit stiffer with the 5100s and the sumos but nothing to be worried about for the family.
My wife definitely noticed the lift with the 5100s and the tires.
