A simplified version of our dual-rate system, the TeraFlex TJ Single-Rate Forged S/T (Street/Trail) Front Sway Bar System features a heavy-duty torsion bar for superior highway handling. The easy engagement knob allows you to go from street to trail in seconds! Simply twist the knob to disengage the bar for unrestricted articulation off-road; then simply twist the knob to re-engage the bar and you are ready for the highway! The sway bar arm features several link mounting points to fine tune the torsion rate.
