Review on 🔧 Rubicon Express RE1482 Replacement Center Pin: Enhance Suspension Performance by Andy Mitts

They worked great with class 4 RE gaskets. For those trying to use them to put together a spring pack, you're doing it wrong. Clamp the spring pack on either side of the center, leaving enough room to work (I used C-clamps spaced about a foot apart), install the spacer and center pin, tighten and remove the clamps . Worked fine for me.
