I lifted mg Frontier by installing longer shackles at the rear and adjusting the torsion of the front suspension. at gained 2" and 1.5" respectively. The problem was the front tires is not cambered correctly, it is wearing out unevenly in the inner side of the tires. It was wheel aligned and cambered by computerized shop. What is the maximum height adjustment of the torsion of a Frontier 4x2 ride? Some have same experience same as this? tnx
