Re: Trailing Arm Bushing Replacement

Are you sure you want to use polyurethane trailing arm bushings? Your trailing arms twist with articualtion. They arme designed to do that to a degree, but polyurethane bushings will make them twist alot more than they were designed and bind up suspension movement.
Rubber bushings will be far better suited for this application as they alow more give allowing more articulation. Nascar guys use the truck arm design and use either rubber or a mono ball style bushing.
I think they know a thing or two about these arms when it comes to performance.
either way thought I would mention that.
