So who would have thought that battery terminals are a critical off-road performance part! It did not occur to us and we almost got stranded in the middle of nowhere because of it!
When testing our ICON suspension system we were trying to see how resistant the suspension was to bottoming out which had us hucking the truck off the bank off a riverbed at 50 plus MPH into the rough rocky riverbed itself.
We didn’t realize it at first but those rocks were BIG under the water! The Icon suspension took it in stride but our battery terminals didn’t!
The heavy battery can move around a lot in severe off-roading with the OEM mounts and even this small amount of movement can fatigue the thin stamped steel factory battery terminals. Ours suddenly snapped and our engine started to run rough. We initially thought we broke something in the motor so we shut the engine off only to find that our electrical system was totally dead! Surprise. Our positive terminal had completely snapped off. Fortunately, we had some zip ties stashed in the glove box and we were able to patch things up enough to get home.
Our negative terminal had bent around and was also ready to break. When we got home we ordered some new OEM terminals to fix things but we wanted something better to make sure this would never happen again.
