Has anyone installed this on a truck with a sway bar?
Yes, but in my experience, the short answer is 'no'.
Not PMF's fault though. If you have seen a front D60 with a sway bar, you will understand how tight everything is.
I also have a PMF drop track bar bracket and it s much beefier than the stock bracket so it requires the end links of the sway bar to be longer to pivot it enough to provide clearance.
The forward facing center piece of the PMF stabilizer uses a back bracket to clam shell the bracket to the axle tube rather than using U bolts. Looks great installed, but the back bracket interfered with the sway bar due to my sway bar being pivoted by the extremely long sway bar end links.
I have not measured to see if using U bolts instead of a back bracket would provide enough clearance but I truly suspect it would not.
Even if U bolts would provide more clearance than the back bracket design, I am not confident that the ideal sway bar end link length could be found that accommodated both a drop track bar bracket and a U-bolted stabilizer.
One or the other? Maybe. I removed my sway bar to get the steering stabilizer mounted.
