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\u003ePrecision-Formed Bracket and Linkage\u003c\/h2\u003e\n\u003cp\u003eThe rear track bar drop bracket is CNC laser-cut and brake-formed, then powder-coated for corrosion resistance. Maintaining proper track bar geometry after a 4.5\" lift keeps the axle centered under the vehicle, reducing bump steer and uneven tire wear that a non-relocated track bar would introduce at lifted ride height.\u003c\/p\u003e\n\n\u003ch2\u003eAdjustable Sway Bar Links with Quality Joints\u003c\/h2\u003e\n\u003cp\u003eThe fabricated rear sway bar links are adjustable and use FK rod ends paired with polyurethane bushings. Adjustability lets the installer dial in the correct length for the lifted geometry rather than accepting a fixed-length compromise, while FK rod ends provide a precise, low-slop pivot that holds its feel over time.\u003c\/p\u003e\n\n\u003ch2\u003eExtended Brake Lines and Bump Stop Spacers\u003c\/h2\u003e\n\u003cp\u003eThe kit includes extended stainless-steel braided brake lines sized for 4.5\" of lift. Factory brake lines pulled taut at full droop are a safety concern, and including extended lines in this kit means that concern is addressed without a separate purchase. Billet aluminum bump stop spacers relocate the bump stop contact point to match the new suspension travel, preventing metal-to-metal contact at full compression.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTrack bar drop bracket:\u003c\/strong\u003e CNC laser-cut, brake-formed, powder-coated steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBump stop spacers:\u003c\/strong\u003e billet aluminum, CNC machined\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSway bar links:\u003c\/strong\u003e fabricated, adjustable, with FK rod ends and polyurethane bushings\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrake lines:\u003c\/strong\u003e extended stainless-steel braided construction\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHardware:\u003c\/strong\u003e all required mounting hardware included\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\u003e21000\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eFitment\u003c\/td\u003e\n      \u003ctd\u003e2007–2018 Jeep JK Wrangler (rear)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eLift Height\u003c\/td\u003e\n      \u003ctd\u003e4.5\"\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eTrack bar bracket material\u003c\/td\u003e\n      \u003ctd\u003eLaser-cut, brake-formed steel, powder-coated\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBump stop spacer material\u003c\/td\u003e\n      \u003ctd\u003eBillet aluminum\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eSway bar link joints\u003c\/td\u003e\n      \u003ctd\u003eFK rod ends with polyurethane bushings\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eBrake lines\u003c\/td\u003e\n      \u003ctd\u003eExtended stainless-steel braided\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd\u003eShip weight\u003c\/td\u003e\n      \u003ctd\u003e17 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 kit is for owners of 2007–2018 Jeep JK Wranglers who are installing an ICON 4.5\" rear lift suspension system and need the complementary hardware (track bar relocation, sway bar links, bump stop spacers, and extended brake lines) to complete the installation safely.\u003c\/p\u003e\n\u003cp class=\"product-fit-no\"\u003eThis kit does not include shocks, springs, or control arms; it is not a standalone lift kit.
