If you’re considering a custom lug or hook you need to consider an LSI plate. This is an insert between the Redco 750 polyurethane which provides added sheer strength for the hook or lug. They are not always necessary as some designs build up a “bump” of extra urethane around the mounting holes, which provides similar support. The LSI plate is made from mild steel and is sandwiched via a “press fit”. The holes on the plate are 1-1/2″ apart. Even though the plate provides additional shear support that does not mean the hook or lug can take significant abuse. The plate is only 0.13″ thick.
