The system ships as four matched assemblies: front and rear 2.5 Series remote-reservoir coilovers with Compression Damping Control Valves, billet aluminum Delta Joint upper control arms, and fabricated rear toe links.\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\u003eRemote Reservoirs and CDCV Tuning\u003c\/h2\u003e\n\u003cp\u003eThe front and rear 2.5 Series coilovers carry remote reservoirs that keep fluid temperatures lower during sustained off-road use, where heat buildup in a conventional shock body degrades damping consistency. Each shock is also equipped with ICON's Compression Damping Control Valve, giving the driver 10 external compression damping settings without removing a wheel. That range covers daily street driving, slow technical terrain, and high-speed desert running without swapping components.\u003c\/p\u003e\n\n\u003ch2\u003eDelta Joint Upper Control Arms\u003c\/h2\u003e\n\u003cp\u003eThe billet aluminum upper control arms use ICON's patented Delta Joint, a high-angle ball joint with a zinc-plated housing and grease-sealed inner workings. The design allows greater articulation than a conventional ball joint while resisting the corrosion exposure that limits a standard uniball in daily-driven applications. On-vehicle caster and camber adjustment means alignment can be dialed in without pulling the arms, and FK rod-end bearings at the toe links reduce deflection at the new ride height.\u003c\/p\u003e\n\n\u003ch2\u003eLift Height, Tire Clearance, and ADAS\u003c\/h2\u003e\n\u003cp\u003eLift heights listed are for a stock-equipped vehicle; adding accessories or weight will shift the range. Diesel-engine submodels achieve a narrower 2–2.75\" front lift range rather than the 2.5–3.25\" figure. The system accommodates OEM wheels and tires. ICON's recommended aftermarket fitments run up to 33x12.50\", and fender trimming is required at that size; larger tires may need additional modification. Advanced Driver Assistance Systems (ADAS) require recalibration after installation.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable front lift:\u003c\/strong\u003e 2.5–3.25\" over stock on gasoline-engine submodels; 2–2.75\" on diesel submodels\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable rear lift:\u003c\/strong\u003e 3–4\" on Tahoe\/Yukon; 2.5–3.5\" on Suburban\/Yukon XL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e10-setting CDCV:\u003c\/strong\u003e external compression damping adjustment on all four shocks without disassembly\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDelta Joint UCAs:\u003c\/strong\u003e billet aluminum arms with zinc-plated, grease-sealed high-angle ball joint and on-vehicle alignment adjustability\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRemote reservoirs:\u003c\/strong\u003e maintain cooler operating temperatures during extended off-road use\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFully rebuildable:\u003c\/strong\u003e all shocks are serviceable and re-tunable\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\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK73104\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2021–2026 Chevrolet Tahoe, 2021–2026 Chevrolet Suburban, 2021–2026 GMC Yukon, 2021–2026 GMC Yukon XL\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront lift range (gasoline)\u003c\/td\u003e\n      \u003ctd\u003e2.5–3.25\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront lift range (diesel)\u003c\/td\u003e\n      \u003ctd\u003e2–2.75\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear lift range (Tahoe \/ Yukon)\u003c\/td\u003e\n      \u003ctd\u003e3–4\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear lift range (Suburban \/ Yukon XL)\u003c\/td\u003e\n      \u003ctd\u003e2.5–3.5\" over stock\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock series\u003c\/td\u003e\n      \u003ctd\u003e2.5 Series, remote reservoir, CDCV-equipped\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock shaft diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock body finish\u003c\/td\u003e\n      \u003ctd\u003eCAD-plated, corrosion resistant\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUpper control arms\u003c\/td\u003e\n      \u003ctd\u003eBillet aluminum with Delta Joint (zinc-plated, grease-sealed)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear toe links\u003c\/td\u003e\n      \u003ctd\u003eFabricated, FK rod-end bearings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eOEM wheel\/tire compatibility\u003c\/td\u003e\n      \u003ctd\u003eYes\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRecommended max tire size\u003c\/td\u003e\n      \u003ctd\u003e33x12.50\" (trimming required)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping weight\u003c\/td\u003e\n      \u003ctd\u003e160 lb\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eCalifornia Prop 65\u003c\/td\u003e\n      \u003ctd\u003eWARNING: This product contains chemicals known to the State of California to cause cancer, birth anomalies, or other reproductive harm.\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 2021–2026 Chevrolet Tahoe, Suburban, and GMC Yukon and Yukon XL owners running gasoline or diesel engines who want a significant, tunable lift with improved off-road wheel travel and the ability to run larger tires, while retaining daily-driver ride quality and factory alignment adjustability.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit any Tahoe, Suburban, Yukon, or Yukon XL submodel equipped with Magnetic Ride Control or Adaptive Air Ride suspension.
