2010-2013 Cummins Adjustable Control Arm Kit (8531-03)

Fits

Note: 2013 models are split-year models. If your 2013 Ram 3500 has radius arms, you must use the 2014+ Dodge Ram kits.

Restore proper geometry and unlock the full potential of your Ram’s suspension with the Synergy Adjustable Control Arm Kit. When leveling or lifting your 6.7L Cummins, maintaining correct caster and pinion angles is critical for predictable handling and driveline longevity. This kit replaces weak factory arms with heavy-duty DOM tubing, engineered to correct suspension geometry on trucks with 0" to 3.5" of lift. Featuring maintenance-free Dual Durometer Bushings, this kit improves ride quality while providing the strength needed for heavy towing and off-road abuse.
