Sure you can argue that the lower trailing arms are not the most important part when linking an off-road truck, but to me they were. Why you ask? Building these arms representes the signifigant completion of the project. The way this truck is going to be built is going to be for lack of a better term, insane. It is a daily driver and need to retain those duties. So EVERYTHING needs to be in order when the time comes. These trailing arms were the last of the 'major' fabrication parts needed. Everything else is either a pre-fab part or is part of the actual build.
So here are the arms. They are the Giant Motorsports WIY Trailling Arms. Fully TIG Welded.
