Hey I am looking at putting an RSK kit and superduty springs (already have a D60 installed) Im looking for the smallest amount of lift to fit 35s because I haul a lot and also is there a way to put rear superduty springs under my Obs too? The reason I am asking is because Im getting a whole set of superduty springs front and rear off my uncles old f350

 

I like sky, they are made in Oregon and have an option for SD springs
