The system pairs CNC-bent 1026 DOM steel tubular upper control arms (featuring ICON's patented Delta Joint) with V.S. 2.5 Aluminum Series internal-reservoir shocks tuned specifically for this application in both length and damping. It is sold as an integrated system only; the control arms and shocks are not available separately for this fitment.\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. Lead times vary by part and some items are built to order, so please allow extra time. We email tracking as soon as your order ships.\u003c\/p\u003e\n\n\u003ch2\u003eNearly 50% More Wheel Travel\u003c\/h2\u003e\n\u003cp\u003eThe tubular upper control arms are engineered to deliver close to 50% more wheel travel compared to stock when paired with ICON 2.0 or 2.5 Series shock absorbers. For a heavy-duty truck used on rough terrain, that additional travel means the suspension can absorb larger impacts without transferring shock load to the frame or cab, translating to better traction, reduced driver fatigue, and more confident handling on uneven ground. Built-in caster correction is machined into the arm geometry, so alignment stays within factory specifications after the lift without requiring additional correction hardware.\u003c\/p\u003e\n\n\u003ch2\u003eDelta Joint: Durability Without the Uniball Trade-Off\u003c\/h2\u003e\n\u003cp\u003eThe upper control arms use ICON's patented Delta Joint, a high-angle ball joint that combines the articulation range of a uniball with the weather resistance of a sealed ball joint. The zinc-plated housing and grease seal protect the joint's internal components from moisture and debris, addressing a known failure point on standard uniball designs in daily-driven applications. The greaseable, metal-on-metal construction extends service life and eliminates the noise that can develop in unsealed joints over time. For a truck that sees both highway miles and off-road use, the Delta Joint removes the maintenance compromise that comes with a traditional uniball.\u003c\/p\u003e\n\n\u003ch2\u003e2.5 Series Shocks Built for Heat and Consistency\u003c\/h2\u003e\n\u003cp\u003eThe included V.S. 2.5 Aluminum Series shocks are nitrogen-charged monotube units with an internal reservoir, a one-piece digressive piston, and vehicle-specific valving. The larger diameter and oil volume of the 2.5 Series provide better heat dissipation and more consistent damping than the V.S. 2.0 Aluminum Series, which matters on long washboard sections or repeated high-speed impacts where smaller shocks can fade. The 7\/8-inch induction-hardened, chrome-plated shock shaft and CAD-plated 1026 DOM steel shock body resist corrosion in mud and salt environments. Both shocks are 100% rebuildable and 100% revalveable, so the investment can be serviced rather than replaced when wear occurs.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDelta Joint upper control arms:\u003c\/strong\u003e patented high-angle ball joint with zinc-plated housing, grease seal, and greaseable metal-on-metal construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1026 DOM steel tubing:\u003c\/strong\u003e CNC bent, semi-gloss black powder coated for corrosion resistance\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBuilt-in caster correction:\u003c\/strong\u003e maintains factory alignment specifications at 0–2 inch lift\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eV.S. 2.5 IR shocks:\u003c\/strong\u003e nitrogen-charged monotube, internal reservoir, digressive piston, application-specific valving\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 aircraft-grade aluminum CNC components:\u003c\/strong\u003e with 7\/8-inch chrome-plated induction-hardened shock shaft\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% rebuildable and revalveable:\u003c\/strong\u003e shocks can be serviced and retuned after installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\n    \u003ctr\u003e\n      \u003cth\u003eSpecification\u003c\/th\u003e\n      \u003cth\u003eDetail\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2011–2019 GM 2500 HD \/ 3500 HD\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Range\u003c\/td\u003e\n      \u003ctd\u003e0–2 inches\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eControl Arm Material\u003c\/td\u003e\n      \u003ctd\u003eCNC bent 1026 DOM steel tubing, semi-gloss black powder coat\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Series\u003c\/td\u003e\n      \u003ctd\u003eV.S. 2.5 Aluminum Series, Internal Reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Design\u003c\/td\u003e\n      \u003ctd\u003eNitrogen-charged monotube, one-piece digressive piston\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Shaft\u003c\/td\u003e\n      \u003ctd\u003e7\/8-inch diameter, induction hardened, chrome plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Body\u003c\/td\u003e\n      \u003ctd\u003eCAD-plated precision machined 1026 DOM steel\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Oil\u003c\/td\u003e\n      \u003ctd\u003ePremium grade 5WT for consistent damping across wide temperature range\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBearings \/ Hardware\u003c\/td\u003e\n      \u003ctd\u003ePTFE-lined spherical bearings, application-specific mounting hardware included\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFactory Wheel Fitment\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003eICON Alloys 18x9 with 5.5-inch backspace \/ 12mm offset; ICON Alloys 20x9 with 5.5-inch backspace \/ 12mm offset\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003e78722\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShip Weight\u003c\/td\u003e\n      \u003ctd\u003e30 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eWho This Is For and Isn't\u003c\/h2\u003e\n\u003cp class=\"product-fit-yes\"\u003eThis system suits 2011–2019 GM 2500 HD and 3500 HD owners running a 0–2 inch front lift who want increased wheel travel, caster-corrected alignment geometry, and a rebuildable shock upgrade over stock, whether the truck is used for daily driving, towing, or off-road use.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit GM 1500 trucks, any GM HD outside the 2011–2019 model years, or applications requiring more than 2 inches of front lift. The control arms are not sold separately from the shocks for this fitment. Buyers seeking a more user-adjustable damping tune should consider ICON's CDC Valve shock option instead.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan the control arms be purchased without the shocks?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eFor 2011–2019 GM 2500 HD and 3500 HD applications, ICON no longer offers the tubular upper control arms as individual components. The control arms are only available as part of this complete shock system to ensure compatibility between components.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWhat is the difference between the V.S. 2.5 and V.S. 2.0 shocks included in similar ICON systems?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe V.S. 2.5 Aluminum Series shocks have a larger diameter and greater oil volume than the V.S. 2.0 Aluminum Series, providing improved heat dissipation and more consistent damping performance, particularly relevant during extended off-road use or repeated high-speed impacts.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eAre the shocks rebuildable after installation?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. The V.S. 2.5 Aluminum Series shocks included in this system are 100% rebuildable and 100% revalveable, meaning they can be serviced, retuned, or refreshed rather than replaced when they reach the end of a service interval.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eWill factory wheels fit after installing this system?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes, factory wheels are confirmed compatible with this system. ICON also recommends specific aftermarket wheel sizes for this application: ICON Alloys 18x9 with 5.5-inch backspace and 12mm offset, or ICON Alloys 20x9 with 5.5-inch backspace and 12mm offset.\u003c\/p\u003e\n\n\u003ch3 class=\"product-faq-q\"\u003eDoes this system include a Proposition 65 warning?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes.
