NOS Koni Sport Adjustables fit!
In [thread https://www.f150forum.com/f38/tire-bounce-255364] THIS [/thread] thread I said I hated the 2-3 tire bounce I was experiencing when I drove over potholes or bumps. The consensus was to try new rear shocks as the OEM Ford 2WD rear shocks are considered awful.
Google'd to see what my options were when I remembered that I had a set of NOS Koni adjustable shocks in the garage from a still born GRM 2000 challenge project. I purchased them in 1999 (they were discontinued even then) and were new in box. Koni part number 8241-1026, I believe they were original fit for a 1970-1979 F150. Koni discontinued these in the late 1990's.
Quick use of a tape measure said the shock body was the same but they were about 2" shorter in extended length than the OEM, and one eyelet bushing was too large.
I previously leveled my 2014 RCRB (6.5') 2WD about 2" in the rear with longer shackles so the Koni extended length was about perfect for my truck. (I wouldn't try with a lifted truck as you would surely top out the shaft).
Back in the early 1990's sport trucks were all the rage and Koni made adjustable sport shocks for just about everything. These are rebound adjustable with a screwdriver in a slot near the top eyelet.
Found an eyelet diameter adapter/bushing for $4 at the local parts store. 10 minutes later they were on.
Even at full soft the Koni's are much stiffer than the factory shocks. Setting to full stiff is comical as the rebound is so stiff that at each bump in the road the truck hunkers down lower and lower (good for Daytona 500 but not so good for the street). I set them to 3/4 full stiff and the handling is AWESOME!!
The tire bounce is gone and the stiffer rebound of the Koni really makes the truck corner much flatter in transitions. LIKE!
YMMV.

Just a quick update. I paired the Helwig 1.5" front swaybar with the shocks this weekend. WOW. While not a GT40 the in-town driving experience is greatly improved. Corners flat with no wallow.
