Re: UHMW ok for body lift spacers?
There is a wide range of hardness in urethane, from skateboard wheels to something similar to a tire. The urethane mounts I used seemed to be about the same hardness as the 25-year old stock mounts I took out.
With body lift mounts being taller, they should probably be harder too, to keep the body from squirming around so much. I've never thought much of those kits with two or three inch thick rubber mounts.
It occurs to me that perhaps the best body lift kit would be a set of stock rubber mounts, or eurethan mounts of similar hardness, and then 1" thick aluminum biscuits to go between the mount and the frame, with correspondingly longer bolts.
Even better would be to use pieces of steel channel an inch tall and two inches wide, to weld onto the frame, effectively raising the frame mounts by an inch. Or two, if you're into that sort of thing.
