Thinking out loud here - caster correction, understand stock caster has a tolerance of +/- 1 deg and normally 1 degree of correction is required / 1 inch of lift. I run 2" lift and have 2 deg caster correction bushes fitted. Saying this, some can get away with retaining stock caster bushes. A wheel alignment should identify if a need exist but I would buy some 2 degree caster correction bushes and a good steering SME would do wheel alignment and fit the bushes at same time . Many suppliers around, superior eng sell them:
