The original lower spring plate (or “Top Hat” as some call it) on VW T25/T3/Vanagon rear suspension arms is pretty thin and weak. Nine out of ten times, when one of these arms has to be replaced, it is simply due to the spring plate being rusted and/or broken. These GoWesty spring plates are thicker and way stronger than the original part, and they can be installed without even removing the arm!
This part comes un-painted because it has to be welded on. Simply drill out the original spot welds, line up the two holes on the replacement part with the existing two holes in the suspension arm, and weld up the other holes. It may sound complicated, but it is actually not that bad. If you can weld, it will be easy as pie!
I have fitted something similar to my own van in the past but these Gowesty trailing arm repair sections are much more heavy duty. These are really well made and thick, they will no doubt outlast your trailing arms.
