DB:
In the late 80's the front sway bar was behind the axle, that's how it was on both my trucks. After identifying a Ford factory Hi Ryder 2" suspension lift in the junkyard on an 89 XLT, I switched over to the BEEFIE in front of axel stock bar available with that lift for my 87 Ranger.
I later found a complete 4" Superlift on another Ranger in the yard. It was also using the same BEEFIE Ford unit. I have yet to need more in the front on the BII.
For my Ranger's rear, I sourced an aftermarket bar through JC Whitney. It was listed as unbranded but I leaned the company was a very respectable, well know suspension company. I have been happy with it's use since 89.
On the 87 BroncoII I decided to be as stable as possible in the rear, chosing the James Duff rear track bars with dual shocks. That "top heavy" BII rides solid, no noticable lean whatsoever!
