How can i find out exactly what size lift i have so i can get the right size springs for the 52" front spring swap. I bought a 6" kit installed from a local shop. I got all springs in the front and a shackle flip in the back. It rides level and the fronts measure out at 47". The backs are @ 52". What lift 52" would i need to switch out for the fronts? Ill add pics asap. Thank you!
