Description
When it comes to lifting your truck, you’ve got plenty of options that go well beyond the amount of lift height and the manufacture. Are you only looking to lift the truck for larger tire fitment, or how about improving the ride quality and overall capabilities of the truck? What about proper alignment with nice level radius arms to avoid bump steer and a dropped track bar to keep it parallel with the drag link like it should be? Have you thought about extended brake lines to ensure you don’t overstretch them with your newfound additional articulation thanks to the progressive rate coil springs and optional leaf spring expansion packs? All of these are reasons why the ICON Stage 2 Suspension System is a great choice for many that will deliver you the ride height you’re after for larger tire fitment, coupled with improved handling, both on and off the street. The Stage 2 Complete Suspension Systems builds on Stage 1 by adding remote shock reservoirs to the front and rear shocks. The remote reservoirs add fluid capacity for increased heat dissipation. Stage 2 also adds ICON's Dual Steering Stabilizer Kit. ICON's FSD Expansion Pack is a desirable upgrade to this Stage 2 Suspension System. This kit modifies the stock rear leaf springs to provide suspension height without lift blocks, and with superior rear suspension performance.
