PP springs vs Eibach Pro-kit

[thornclaw]

But from what I see you have a 2015 Gt (like mine) and from another post I read it's auto. So when you say that you have just took off the pp1 springs you mean that you put them on before, because them are not the original springs of your car. In 2015-17 there where not a pp1, just the pp, and wasn't available for auto transmission.
That code of your springs is effectually the same code of the unknown springs that I have bought.
So if that is the case I have change mine 2015-17 PP springs (fr3c-5560-ha) for the 2018+ PP1 springs (jr3c-5560-ha). So it's an upgrade, I hope..

yes you are correct
i upgraded to these from the base springs
i ordered them from levittown after providing them the vin of a local pp1 car

Looking at the OP photo of the two boxes of springs the front springs have a different number of coils from the top box and the bottom box. The rears look like they are the same in both boxes. They all look to be Ford springs. So, something is different, at least on the front springs
