Hi all, I have a 91 sierra which I have fitted 2 inch lifted EFS springs and Rancho shocks. Since I have fitted this suspension the car is almost 2 inches lower on the drivers side. The front and back shackles are both pushed out on the drivers side and are almost vertical on the passenger side. I have tried swapping the springs from side to side but with no luck. Has this happened on other Sierra's or just mine? Could the chassis be twisted? If so how can I check that?
