Take Full Control Of Your Suspension With True Long Arm Performance

If you’re building your Ram 2500 or 3500 to handle bigger tires and tougher terrain, the Synergy 3 Inch Long Arm System delivers exactly what serious drivers are looking for. This setup doesn’t just lift your truck, it completely transforms the way it handles on and off the pavement. With massive 2 inch DOM steel lower long arms and properly tuned coil springs, you get smoother travel, improved articulation, and far better control when conditions get rough. It’s built for 2010-2013 diesel 2500s and 2010-2012 diesel 3500s, and it clears up to 37 inch tires with no rubbing. The long arms are designed to maintain factory geometry, so you get better flex without giving up the comfort or road manners of a daily driver. This system replaces your factory overload spring with a progressive add-a-leaf pack, helping the rear end soak up hits while keeping driveline angles in check. From work trucks to weekend rigs, this kit gives your Ram the performance edge it was always capable of.

Precision Geometry Meets Heavy Duty Strength For Real World Performance

The Synergy 3 Inch Long Arm System is a comprehensive suspension upgrade engineered to increase articulation, ride quality, and long-term durability. It includes progressive wound coil springs built using CNC hot winding for consistent rate control and smoother compression under varying loads. The front long arms are constructed from 2.00 x 0.250 inch wall DOM tubing, offering best-in-class strength and ground clearance, while upper arms use crush-resistant 1.75 x 0.188 inch tubing for added support and adjustability. Each arm is equipped with Synergy Dual Durometer Bushings and Johnny Joints to reduce vibration, maximize flex, and eliminate maintenance. A high-clearance adjustable track bar centers the axle under lift and works with the included cam bolt eliminator kit to lock in your alignment settings. In the rear, the 5-leaf add-a-leaf pack replaces the stock overload spring to improve ride compliance while delivering a mild lift. This system is finished in a durable powder coat and designed, tested, and manufactured in the USA to handle aggressive use in real-world environments.
