I have a 2002 ford ranger edge 4x4 4.0. I am looking for upgrade on rack and pinion system and steering column/shaft assembly. For the steering shaft i need to know the splines on the lower column and the lengths of upper and lower shafts. Also do they make upgraded torsion bars? I am trying to rebuild my ranger to last. Have done frame and cab re done now i am on the front end and have gotten lower control arms so far. Have a 4inch body lift from PA and the procomp leveling kit. Please help i have to go back fishing soon
