Powertrix Rear Camber Arms are made of Chromalloy for a lightweight construction that focuses on durability, strength and performance. These components also feature top quality Teflon ball joints with dust boots for added protection and longevity. Unfortunately, the stock rear link has very little adjustment, limiting alignment possibilities and set-ups. With 4 degrees of adjustability, the Powertrix Rear Camber Arms can be set up with alignments anywhere in between factory OEM specs to preserve tire wear on the street to full on racing applications for maximizing traction in the corners.
