I'v had this question for awhile. If the Acherman angle is correct on the top nuckle arms you sell (and I feel they are because by truck drives very well with the x-over steering), then why do other shops have passenger side nuckle arms that are longer and have two holes in the front one for the drag link and one for the tie rod. These would allow tie rod over and the longest drag link for less bump-steer. I'v seen these for D44 and D60 nuckles. dose the acherman angle calculation use wheel base as a component. if so then one for a blazer,pick up ,and sub. would all have to be different. what is the calculation for the Acherman angle?
