Sounds like the springs may be too short for the setup you have. Some aftermarket springs are made in the stock length (allows for use of the stock length shackles) but with the higher arch, the ends end up much closer together than stock, resulting in the shackle swinging too far forward. They may even be lift springs for another application and are just too short. They are likely very stiff if they sit with all that arch at rest.


A longer shackle might help, but the real fixes are to either move the front hanger back or the rear hanger forward or get a spring with a longer length leaf.
