Built to outperform, BDS Suspension engineered a 8-inch lift kit with long arm conversion for your 2009-2013 Dodge RAM 2500 diesel powered truck that maximizes performance on and off road. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 38" tires. BDS built the long lower control arms to reduce caster change through wheel travel which creates a more controlled feeling in the steering wheel. This long arm long arm system retains the factory triangulation of the arms which adds to the stability of the suspension system.
