UMI trailing arms with Roto‑Joint technology for 2008–2009 Pontiac G8 and 2010–2014 Camaro use a pivot ball lined with a greaseable Delrin race to deliver bind‑free articulation and quiet street manners. The Roto‑Joint provides about 28° total movement for low friction operation, improving rear stability, reducing wheel hop and allowing precise rear end control. They bolt in directly and come fully assembled.
