Fabtech 5" RADIUS ARM KIT W/PERF SHKS 2019-21 RAM 2500 4WD K3180

Improving on the Ram suspension design, Fabtech offers their trademark Radius Arms in a complete lift kit system. These exclusive tubular Radius Arms have recognizable dimple die side plates for superior strength and a signature of quality. The rugged Arms provide increased caster for use with oversized tires and lifted suspension heights. The factory front Ram coil spring has a noticeable bow to it with a very high spring rate for the weight rating of the vehicle. This creates a harsh ride with a nervous feel from the suspension. To correct this, Fabtech uses a straight vertical coil design. In order to utilize a straight coil, the lower spring seat mount must be modified via a Fabtech patented angular spring mount that attaches to the stock seat. This eliminates the bow to the spring and allows for a lower rate with a straight coil for a supple ride without sacrificing load carrying capacity. A Fabtech exclusive. For the rear, this lift kit has the perfect balance between ride quality and retaining the factory carrying capacity. By utilizing a dual rate spring design, it provides a good highway ride in the first stage of compression and then the second stage handles heavy loads. Heavy duty 1/4in thick steel front and rear Track Bar drop brackets center the axles under the vehicle with the new ride height. A Fabtech innovation with this Ram lift kit is the heavy duty steel front bump extensions. They retain the stock bump stop cushions for progressive damping and will not allow the suspension to over travel. This is a superior feature compared to replacement long length urethane bump stops as they can push out under harsh conditions. FEATURES: Fabtech's trademark Radius Arms with recognizable dimple die side plates providing additional strength and increased caster. Front straight Coil Springs with Fabtech's patented angled mounts for smooth ride. Heavy duty Track Bar drop brackets center the axles under vehicle for proper tracking. Dual rate rear coil spr
