New never used.  Replacement steering system to reduce the nasty toe-out associated with bagged S10s. When used with drop spindles, this kit also keeps you from having to notch the frame up to a 27" OD tire and over that only small notches are required (unlike the large notches required for stock tie-rods). This system works with both stock arms and all major brands of aftermarket arms that use factory length dimensions (Thor Bros, MMW, RideTech, Choppin Block, etc). If changes have been made to the stock control arm lengths then that will of course affect geometry.
