The system ships as three matched sub-assemblies and installs with no drilling, cutting, or welding.\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\u003eMore Wheel Travel, Front and Rear\u003c\/h2\u003e\n\u003cp\u003eThe front 2.5-inch VS Internal Reservoir coilovers are tuned specifically for the GM 1500 platform and paired with ICON-engineered Eibach coil springs. The internal reservoir extends the shock's cooling capacity under sustained off-road use, which keeps damping consistent when the terrain demands repeated, hard compressions. Height adjustability across the full 1–3-inch range means the lift can be dialed to clear a specific tire size without sacrificing ride quality at the chosen height. The included 2.5 Aluminum Series piggyback rear shocks carry vehicle-specific valving that balances rear damping to match the front, so the truck does not feel mismatched between axles on rough ground.\u003c\/p\u003e\n\n\u003ch2\u003eDelta Joint Upper Control Arms\u003c\/h2\u003e\n\u003cp\u003eThe tubular upper control arms use ICON's patented Delta Joint, a high-angle ball joint engineered to combine the articulation range of a uniball with the sealed, serviceable construction of a conventional ball joint. A zinc-plated housing provides corrosion resistance; a grease seal keeps contaminants away from the joint internals; and a greaseable, metal-on-metal design supports long service life without the noise or weather-exposure concerns associated with an open uniball. FK rod end bearings at the lower bar pin reduce deflection and extend longevity. For a daily-driven truck that also sees off-road use, the Delta Joint removes the trade-off between angularity and durability.\u003c\/p\u003e\n\n\u003ch2\u003eBolt-On Construction, Aircraft-Grade Materials\u003c\/h2\u003e\n\u003cp\u003eEvery structural component is CNC-machined from 6061 aircraft-grade aluminum. Coilover shock bodies are CAD-plated for corrosion resistance and built with 7\/8-inch shafts. The rear shock cylinders are one-piece impact-extruded aluminum, which produces a consistent finish and eliminates seam-related corrosion paths. The entire system installs without modifying the factory frame or body (no drilling, cutting, or welding required) and does not change the truck's towing capacity.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront coilovers:\u003c\/strong\u003e 2.5-inch VS Internal Reservoir, vehicle-specific tune, ICON-engineered Eibach springs, 1–3-inch height adjustable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUpper control arms:\u003c\/strong\u003e tubular construction with patented Delta Joint (large taper), FK rod end lower bar pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear shocks:\u003c\/strong\u003e 2.5 Aluminum Series piggyback reservoir, vehicle-specific valving, compatible with 0–1.5 inches of rear lift\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterials:\u003c\/strong\u003e 6061 aircraft-grade aluminum CNC components, CAD-plated coilover bodies, 7\/8-inch shafts, one-piece extruded aluminum rear cylinders\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInstallation:\u003c\/strong\u003e 100% bolt-on, no drilling, cutting, or welding required; OEM wheels and tires fit confirmed\u003c\/li\u003e\n  \u003cli\u003e\u003cstrong\u003e2WD and 4WD compatible\u003c\/strong\u003e\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\u003e2014–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 (2WD and 4WD)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Lift Range\u003c\/td\u003e\n      \u003ctd\u003e1–3 inches (height adjustable)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Lift Compatibility\u003c\/td\u003e\n      \u003ctd\u003e0–1.5 inches (rear shocks)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Diameter\u003c\/td\u003e\n      \u003ctd\u003e2.5 inches\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFront Shock Type\u003c\/td\u003e\n      \u003ctd\u003eVS Internal Reservoir coilover\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eRear Shock Type\u003c\/td\u003e\n      \u003ctd\u003e2.5 Aluminum Series piggyback reservoir\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShock Shaft Diameter\u003c\/td\u003e\n      \u003ctd\u003e7\/8 inch\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eUpper Control Arm Joint\u003c\/td\u003e\n      \u003ctd\u003ePatented Delta Joint, large taper, greaseable\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eMaterial\u003c\/td\u003e\n      \u003ctd\u003e6061 aircraft-grade aluminum (CNC machined); CAD-plated shock bodies; one-piece extruded aluminum rear cylinders\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSystem Components\u003c\/td\u003e\n      \u003ctd\u003e71505: 2.5 VS IR Coilover Kit (qty 1); 78601DJ: Tubular UCA Delta Joint Kit, large taper (qty 1); 77700P: 2.5 VS Piggyback Rear Shock Pair (qty 1)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSKU\u003c\/td\u003e\n      \u003ctd\u003eK73003A\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShipping Weight\u003c\/td\u003e\n      \u003ctd\u003e92 lb (ships in multiple boxes)\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 Stage 3 system suits 2014–2018 Chevrolet Silverado 1500 and GMC Sierra 1500 owners (2WD or 4WD) who want 1–3 inches of adjustable front lift, meaningfully more wheel travel than stock, and a matched front-to-rear damping upgrade for mixed on-road and off-road driving. OEM wheels and tires fit without modification at the supported lift heights.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis system does not fit Silverado or Sierra SUV models (Suburban, Tahoe, Yukon), Hybrid-drivetrain 1500 variants, or trucks equipped with Magnetic Ride Control. It requires OE factory spindles and is not compatible with any aftermarket spindles. Slight modifications to factory shock mounts may be required (Application Note #48). Rear shocks in this kit support 0–1.5 inches of rear lift on most models; rear lift beyond that range requires a different rear shock. Tires larger than 33x11.50 inches may require fender trimming or additional modifications.
