Anyone use a TC-EZ ride 3\" front and rear spring lift? Trying to figure out if I can use a zerorate up front to move the front axles forward and still sit level? OR, If I am going to need to order 2" fronts and 3" rears? The fronts now are pretty saggy (in negative arch) and the rears seem ok, and the truck is currently pretty close to level. It has the three spring pack up front and the 5 or 6 leaf out back with an overload bar. (these are not stock springs, they came from a truck in 1990, not off a 90, but got changed in 90). Anyhow, people with 3" springs front and rear.... Level or can a zerorate be used up front?
