ICON engineers developed this leaf pack to address the factory spring's tendency toward stiffness on smaller, choppy terrain. The base spring rate is slightly lighter than OEM for improved ride quality and additional droop travel, while the included add-in leaf provides 20% or 40% rate increases for trucks carrying significant weight from accessories like chase racks, roof top tents, or heavy cargo.

This multi-rate leaf spring represents the culmination of extensive testing across diverse terrain—from brutal Southwest deserts to deep Michigan snow to wooded East Coast trails. When paired with ICON 2.5 Aluminum Series rear shocks and optional 1" lowering shackles, this system delivers exceptional performance for both daily driving and extreme off-road adventures.

Kit Includes: Multi-rate leaf pack with add-in leaf for spring rate adjustment
