Fabtech's Radius Arm lift kit upgrades the Ram suspension with heavy-duty components engineered for lifted applications and oversized tires. The kit features tubular Radius Arms with dimple die side plates for added strength and increased caster for improved tracking. Front suspension is revised with straight vertical coil springs paired with Fabtech's patented angled spring mounts that modify the lower spring seat while using the stock seat, eliminating the coil bow and allowing a lower spring rate for a smoother, more controlled ride without reducing load capacity.
Rear suspension uses a dual-rate coil spring design to deliver a comfortable highway ride in light compression and strong support under heavy loads. Heavy-duty steel track bar drop brackets center the axles at the new ride height, and steel front bump stop extensions retain the factory bump stop cushions for progressive damping and to prevent suspension overtravel.
