Backstory:
Three years ago when I swapped in the 1ton axle, I moved said axle back 5".
That created a shallower angle for the shocks:
so I added OEM upper shock mounts to recover said angle:
Fast forward to this month;
I lowered the suspension causing concern with the longer 1ton shocks bottoming out.
So I moved the 1ton shocks to the factory original shock mounts (extending shocks).
Knowing shallow-mounted shocks have decreased efficiency; I decided to mount the Bronco (1/2ton) shocks to the added upper shock mounts and lower long bolt.
So far I like how it's handling; going over dips the rear leaf springs are less 'springy' because shock set up only allows 1 to 1.5 rebounds.
My OCD demands that I check suspension/shock droop relation.
I'm looking at these axle shock mounts to properly mount AND move lower shock mounts outward as suggested by a member here:
But the bottom line to answer your question:
Said experiment didn't cost me any money and I'm retired and have nothing but time.
