Anyway, I have never in my life seen adjustable LIFT BLOCKS.
i do suspect these could be very helpful in adjusting an axle assembly forward or rearward to accomodate a driveline or maybe ever interference with the lip of a Fenderwell perhaps. I have no idea who makes them.
I'm wondering if these adjustable contraptions are more of a Liability than a benefit.
They'd maybe be OK for a TRAILER QUEEN. LoL
I think I have seen something like that for racing before. I would not feel comfortable running them on a daily driver unless they could be locked into place once adjusted.
Interesting find for sure. X2 not sure if it is for a vehicle application. The adjustable part with the "pin" looks bigger than the leaf spring pad center pin hole and or the leaf spring center pin head. So not really adjustable in height, it says provided 2.5 worth of lift. But more for like changing the wheel base. They also look a lot longer than a normal OEM block. If the nut or bolt head has a hole in it you can either cotter pin (if it is a thru hole) or safety wire it tight.
