MFR161048-6 Mopar torsion bar to coilover conversion. This torsion bar to coilover conversion comes with our billet aluminum upper adapters, QA1 externally adjustable coilovers, countersunk allen bolts, and upper cross bolt. Some reinforcing of the upper shock towers and lower arm retention may be necessary. A-body Mopars should use our single adjustable upper control arms or bent style bushed control arms for adequate clearance. B and E-bodies can use any of our tubular upper control arms. Available with single or double adjustable coilovers. Single adjusts the dampening rate for both extension and compression simultaneously. Double allows extension and compression to be adjusted independent from each other.
