The system pairs ICON V.S. 2.0 Aluminum Series IFP front and rear shocks with a Delta Joint tubular upper control arm kit, tuned specifically for the high spring rates of the GM HD factory torsion bar setup. OEM wheels and tires are confirmed to fit; the system is also compatible with select ICON Alloys aftermarket wheels.\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.

ICON's vehicle-specific damping tune addresses this directly, delivering controlled, compliant ride quality whether the truck is loaded at a work site, towing a trailer, or running a dirt road to a trailhead. Towing capacity is not reduced by this system.\u003c\/p\u003e\n\n\u003ch2\u003eDelta Joint UCAs: Durability Without the Uniball Trade-Off\u003c\/h2\u003e\n\u003cp\u003eThe included tubular upper control arms use ICON's patented Delta Joint, a high-angle ball joint designed to match the articulation range of a uniball while eliminating its main weakness in daily-driven use: exposure to the elements. A zinc-plated housing provides a first layer of corrosion resistance; a grease seal keeps contaminants away from the joint's internals; and a greaseable, metal-on-metal design extends service life while allowing noise-free operation. The result is a UCA that handles greater angularity than a conventional ball joint and greater durability than an open uniball.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-On Installation, Fully Serviceable Shocks\u003c\/h2\u003e\n\u003cp\u003eThe Stage 2 system mounts entirely to existing factory locations. No drilling, cutting, or welding is required. The 6061 aircraft-grade aluminum CNC-machined shock bodies carry corrosion-resistant plating, and the shocks are fully serviceable after installation, so the system can be rebuilt rather than replaced when it eventually needs attention.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVehicle-specific shock tuning:\u003c\/strong\u003e front and rear damping calibrated for the GM HD factory torsion bar spring rate\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDelta Joint UCAs:\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\u003e100% bolt-on:\u003c\/strong\u003e no drilling, cutting, or welding required for installation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 aluminum construction:\u003c\/strong\u003e CNC-machined components with corrosion-resistant plated shock bodies\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully serviceable shocks:\u003c\/strong\u003e can be rebuilt in the field or shop after extended use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOEM wheel and tire fitment confirmed:\u003c\/strong\u003e stock wheels and tires clear the system without modification\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\u003e2001–2010 GM 2500HD \/ 3500HD\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\u003eSystem Components\u003c\/td\u003e\n      \u003ctd\u003e2× V.S. 2.0 Aluminum Series IFP front shocks (ICON 76528), 2× V.S. 2.0 Aluminum Series IFP rear shocks (ICON 76529), 1× Delta Joint tubular UCA kit (ICON 78550DJ)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Body Material\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum, CNC-machined, corrosion-resistant plated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUCA Joint Type\u003c\/td\u003e\n      \u003ctd\u003eICON patented Delta Joint (high-angle, greaseable, zinc-plated housing)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM Wheel\/Tire Fitment\u003c\/td\u003e\n      \u003ctd\u003eConfirmed compatible\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended Aftermarket Wheels\u003c\/td\u003e\n      \u003ctd\u003eICON Alloys 17×8.5\" (5.25\" backspace \/ 13mm offset); 18×9\" (5.50\" backspace \/ 12mm offset); 20×9\" (5.50\" backspace \/ 12mm offset)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaximum Recommended Tire Size\u003c\/td\u003e\n      \u003ctd\u003e33×11.50\" (larger tires may fit but require fender trimming and modifications)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK77101\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 2001–2010 GM 2500HD and 3500HD owners who want improved on- and off-road ride quality at 0–2 inches of lift without giving up towing capacity or OEM wheel fitment.
