The RE short-arm with drop brackets is a good design and has been well proven over the many years it has been out, but they're newer longarm kit is a terrible design if you ask me. Full Traction has a great reputation and the 2 issues with them are they only sell kits and their arms hang kinda low if you're doing rock-crawling. Another company worth looking into is TnT Customs, their longarm kit would be my choice, probably rounded out with Rubicon springs and Bilstein shocks.
