The Tuff Country Long Arm Upgrade Kit for 2003–2013 Dodge Ram 2500 4x4 (for models with 2–6 inch lifts) replaces factory control arms with longer upper and lower arms to reduce control-arm angle, soften the ride, cut bump steer and increase suspension articulation for improved handling. Both arms use greaseable, rebuildable flex joints to reduce binding and preserve off-road durability while providing a more controlled ride.
