Re: TeraFlex Front Forged Arm Dual Rate S/T Swaybar System advice?
Do you go offroading on difficult trails? The swaybar system you are looking at is basically a torsion bar that allows the front axle to articulate more that the stock unit.
It's pretty pricy and only necessary for those going off road in my opinion. An alternative for off road use at a fraction of the price would be swaybar disconnects by JKS, Teraflex, and others.
If you often hit the trails, the used unit you asked about is a good price you should consider.
