What I did the first time I lowered my Spacecab was ad 3" blocks to the rear after removing the overload leaf, then instead of turning the torsion bars down, mark their thread location and then loosen the bolts and hammer the fronts of the torsion bars out of the splins and respline them about 3 or 4 notches. Pound them back in and then tighten the bolts back up to the same position on the threads. You may need to cut or pull the bump stops depending on how low you go. The truck should ride the same, only lower. Good luck
