I do get the traction control kicking in every once in a while. I didn't notice it at all for about the first week, but if i hit a slow speed turn too fast like in town somewhere it will kick in for a second. Also seems to be pretty consistant when pulling out of my work, wheels turned, pulling out from a stop to merge into traffic it will kick in for a second like my tires are spinning but they aren't... I am puzzled also. Mine is nowhere near as bad as the other 2 i have seen do this. It happens so little its almost a non issue but i would like to know what is causing it. I actually called Zone about it for a customers truck and zone said it could NOT be the lift since it complies with the federal mandated stability testing... My customer did tell me he put his stock wheels and tires back on and it didnt do it anymore. I have not tried that because like i said mine doesnt really happen enough to be a problem... As for alignment, i think that may have something to do with why it's worse on some trucks than others. I cut the recommended 5/8 off my outer tie rods and 3/8 off my inners and when i went to align it, my tie rods were bottomed out and couldnt get my toe in line. Had to pull it back apart and cut an additional 1/4 off each inner tie rod to properly set the toe. Camber and Toe specs are the same for factory and zone, zone does recommend a bit higher caster than factory. I think zone makes a good product and i have no regrets whatsoever about installing their lift, but it does seem like they may have an issue since there are multiple trucks with this lift having the same issue. Wonder if the bds has the same problem? Its basically the same lift design...
