Rear Anti-Sway Bar for 2015 Ram 1500 4x4

Question:

Hello, Im trying to decide which size sway bar to choose for a 2015 ram 1500 4x4 reg cab short bed with an 800lb popup camper in the back. I have helper bags installed that are tied to same air hose. It looks like you have several options that will fit with multiple diameters from 7/8 to 1 5/16. Thanks

Hello Lee; for a rear anti-sway bar on your 2015 Ram 1500 4x4 I recommend the Roadmaster. Their anti-sway bars are well constructed, reliable, and backed by a limited lifetime warranty. The 1-1/2" diameter and 1-3/8" diameter are actually designed for the Rebel so you can rule those out. That makes for an easy decision since the Roadmaster Rear Anti-Sway Bar - 1-1/8" Diameter # RM-1129-135 is the only option.

Hey Lee, how did the Roadmaster rear anti-sway bar work out on your Ram 1500 with the camper loaded? Your feedback could really help others trying to dial in their setup for similar weight and ride conditions.
