The system pairs custom-valved 2.5\" remote reservoir coilovers front and rear with tubular upper control arms, tubular rear lower links, and heavy-rate rear coil springs engineered for Broncos carrying extra gear weight. Two-door Broncos will sit taller than the stated lift figures.\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.

On repeated hard runs (washboard roads, rock crawling, high-speed desert terrain), standard shocks can overheat and cavitate, causing damper fade and a loss of control feel. The remote reservoir design resists that fade, keeping damping consistent through extended rough-terrain use. Coilover ride height is adjustable, and 7\/8\" diameter shafts with corrosion-resistant CAD-plated bodies are used throughout.\u003c\/p\u003e\n\n\u003ch2\u003eTubular Control Arms and Rear Links Free Up Articulation\u003c\/h2\u003e\n\u003cp\u003eThe tubular upper control arms provide caster correction and incorporate ICON's Delta Joint PRO (U.S. Pat. 10,731,700), which allows up to 90 degrees of total articulation. Greater articulation means the front suspension can follow terrain more closely without binding, which translates directly to traction and steering feel on uneven ground. The tubular rear lower links are adjustable for pinion angle and use dual-durometer greaseless bushings at one end and FK rod ends at the other, improving rear articulation and ground clearance over the stock links.\u003c\/p\u003e\n\n\u003ch2\u003eHeavy-Rate Rear Springs for Loaded Broncos\u003c\/h2\u003e\n\u003cp\u003eThe rear coilovers in this Stage 5 kit use ICON's progressive dual-rate heavy-rate coil springs, mounted shaft-up. These springs are optimized for Broncos that regularly carry extra gear, rooftop tents, or other rear-loaded weight. When the Bronco is unloaded, the stiffer spring rate will produce a slight positive rake (nose-down attitude). This is expected behavior specific to the heavy-rate tune and is not a fitment or installation problem.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFront travel:\u003c\/strong\u003e up to 11.5\" with 35x12.50 tires\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRear travel:\u003c\/strong\u003e up to 14\" with 35x12.50 tires\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDelta Joint PRO UCAs:\u003c\/strong\u003e patented tubular upper control arms with 90-degree articulation and caster correction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable rear lower links:\u003c\/strong\u003e tubular design with FK rod ends and dual-durometer greaseless bushings for pinion angle adjustment\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e6061 aircraft-grade aluminum components:\u003c\/strong\u003e CNC machined; PTFE-lined spherical bearings and application-specific hardware throughout\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e100% bolt-on installation:\u003c\/strong\u003e no drilling, cutting, or welding required\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\u003eK40005TX\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eVehicle Fitment\u003c\/td\u003e\n      \u003ctd\u003e2021–2026 Ford Bronco (Non-Sasquatch, 4-door baseline for lift figures; 2-door sits taller).

Running 35\" or larger tires requires removal of the factory crash bars (ICON's High Clearance Crash Bar kit is sold separately). Running 37\" or larger tires requires optional up-travel limiters (part #611075 front, #611074 rear, sold separately) and may also require crash bar removal. ADAS recalibration is required after installation. Rear reservoir brackets may interfere with some aftermarket step or rock slider mounts, and fitment testing was performed with ICON and OEM steering components only; certain aftermarket steering components may not clear the front coilovers.\u003c\/p\u003e\n\n\u003ch2\u003eCommon Questions\u003c\/h2\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWill this system fit a Bronco with the Sasquatch Package?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eNo. The ICON Stage 5 Tubular system (K40005TX) is engineered and lift-rated specifically for 2021–2026 Ford Broncos without the Sasquatch Package. Lift heights and all application notes are based on Non-Sasquatch-equipped vehicles. A separate ICON system is required for Sasquatch-equipped Broncos.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eCan I run 37\" tires with this suspension system?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe Stage 5 system can be used safely with 37\" and larger tires. Doing so requires ICON up-travel limiters (part #611075 for the front, part #611074 for the rear), which are sold separately. Crash bar removal may also be required when running 37\" tires, though retaining crash bar functionality is recommended where possible using the ICON High Clearance Crash Bar kit.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eDo the factory crash bars need to come off for 35\" tires?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eYes. On Non-Sasquatch Broncos, the factory crash bars must be removed to clear 35\" and larger tires. ICON offers a High Clearance Crash Bar kit (part #42000) as a replacement for owners who want to retain crash bar functionality while running larger tires. That kit is sold separately from this Stage 5 system.\u003c\/p\u003e\n\u003ch3 class=\"product-faq-q\"\u003eWhat does the heavy-rate rear spring mean for everyday driving?\u003c\/h3\u003e\n\u003cp class=\"product-faq-a\"\u003eThe ICON heavy-rate rear coil springs in this Stage 5 kit are optimized for Broncos carrying extra weight in the rear, such as gear or a rooftop tent.
