About this kit
40-Inch Black Series Curved LED Kit, fitment-checked
Rough Country 70570B is a 40-inch curved LED light bar kit for 2011-2018 Ram 2500/3500 4WD trucks. It combines the hidden curved bumper mount (70569) with a 40 Inch Black Series dual-row curved LED light bar (72940BL). Front tow hooks must come off, and the mount cannot be run alongside the Rough Country 20-inch hidden bumper brackets (70206) — only one bracket kit fits at a time.
This 40-inch curved LED light bar kit for the 2011-2018 Ram 2500/3500 4WD bolts on with the brackets tucked out of sight behind the bumper, so the factory front end stays largely intact. Fitment covers 4WD trims from Tradesman and ST through Laramie Longhorn and Limited, plus Power Wagon on the 2500. The mount takes curved bars only, sized for 8mm mounting posts spaced 42 3/16 inches apart, and it will not accept Rough Country X5 bars. Front tow hooks are removed during installation. A downloadable installation guide is available.
