Fabtech 19-22 Ram 2500 4WD 5in Radius Arm Kit w/Stealth

If you're looking to give your 2019-2021 Ram 2500 4WD a significant lift while improving its on-road manners, this Fabtech Radius Arm Kit is a solid choice. This system addresses the factory suspension's tendency for a harsh ride and nervous feel, especially with lifted heights, by redesigning key components. It's designed to handle larger tires and provide a more comfortable experience without sacrificing your truck's load-carrying ability.

At the heart of this kit are Fabtech's signature tubular Radius Arms, featuring dimple-die side plates for added strength and a distinctive look. These arms also increase caster, which is crucial for proper alignment when running oversized tires and a lifted suspension. Fabtech tackles the factory coil spring's aggressive bow and high spring rate by using a straight vertical coil design. They've developed a patented angular spring mount that attaches to the stock lower spring seat, allowing the straight coil to operate more smoothly for a supple ride, while still maintaining load capacity. For the rear, a dual-rate spring design is employed, offering a comfortable highway ride that transitions to robust support for heavy loads.

To ensure your axles stay centered under the vehicle at the new ride height, this kit includes heavy-duty 1/4-inch thick steel front and rear Track Bar drop brackets. A notable innovation from Fabtech is the inclusion of heavy-duty steel front bump extensions. These extensions work with the stock bump stop cushions for progressive damping and prevent suspension over-travel, offering a more reliable solution than some urethane bump stops that can push out under stress.
