Aluminum Series shocks, an adjustable track bar, and tubular steel links engineered and tuned together as a complete system. Springs in this kit are rated for diesel engines only.\u003c\/p\u003e\n\u003cp class=\"product-shipping-note\"\u003e\u003cstrong\u003eShipping:\u003c\/strong\u003e ICON parts ship direct from ICON Vehicle Dynamics, mostly by UPS Ground.

Aluminum Series front shocks, rear shocks, an adjustable track bar, and tubular steel links. That matters because damping curves, spring rates, and link geometry interact: a shock tuned for this spring rate delivers consistent damping across its full stroke in a way a generic shock cannot. The result is predictable handling on pavement and composed, controlled travel off-road without requiring driveshaft modifications.\u003c\/p\u003e\n\n\u003ch2\u003eShocks Built for Serviceability and Corrosion Resistance\u003c\/h2\u003e\n\u003cp\u003eThe 2.5\" V.S. Aluminum Series shocks use one-piece impact-extruded aluminum cylinders, which resist corrosion and maintain a consistent finish over years of exposure to road salt, mud, and water crossings. Internal components include FK bearings, billet top caps and rod ends, and 7\/8\" shafts. The shocks are fully serviceable, so internal components can be rebuilt rather than requiring full shock replacement when they eventually wear, a meaningful long-term cost difference on a truck used hard.\u003c\/p\u003e\n\n\u003ch2\u003eAdjustable Track Bar and Tubular Links\u003c\/h2\u003e\n\u003cp\u003eThe adjustable track bar uses PTFE-lined FK bearings in place of the factory's rubber joints, improving rigidity and eliminating the flex that allows the front axle to wander under load. Adjustability lets the installer center the axle precisely under the truck after the lift is set. The fixed tubular steel upper and lower links replace factory link bushings that introduce bind at the limits of suspension travel; the steel tubes increase strength and extend the alignment range available to the installer.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDual-rate coil springs:\u003c\/strong\u003e match-tuned to the 2.5\" V.S.

The ICON Stage 4 system for 2003–2012 Ram 2500\/3500 4WD is confirmed compatible with OEM wheels and tires. For aftermarket fitment, ICON recommends 17×8.5\", 18×9\", or 20×9\" wheels and tires up to 33×11.50\"; larger tires may require fender trimming.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre driveshaft modifications required?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo driveshaft modifications are needed to install the ICON Stage 4 Suspension System on a 2003–2012 Ram 2500\/3500 4WD.
