Lca bushing help.

Consider these points... All too often the D.I.Y. guy would tighten the press fitted parts in the wrong position then when the arm moved to ride height position the rubber in the bushing ripped apart.
Aftermarket poly urethane bushings are slip fit too, yet seem to work.
I don't know if your aftermarket mfgr took any of this into consideration.
Personally, I might rather have this fitment along with greaseable pivot pins.
