{"product_id":"dirt-king-billet-upper-control-arm-silverado-zr2","title":"Dirt King Billet Upper Control Arm - [Silverado ZR2]","description":"\u003cp\u003eThe Dirt King Billet Upper Control Arms are precision-machined from 6061 aluminum, offering exceptional strength and a refined appearance. Designed to optimize suspension geometry, these arms allow for increased front lift and suspension travel when paired with Dirt King shocks. Factory control arms often compromise geometry and structural integrity due to excessive articulation at stock joints, but Dirt King arms solve this with improved caster settings and re-engineered pivot angles for better handling and articulation.\u003c\/p\u003e\n\u003cp\u003eA key feature of the billet arms is the adjustable inner pivot system, available in two configurations. The maintenance-free Probearing SilentSpin bushings provide superior ride comfort, with a polyurethane outer layer that dampens road noise and a self-lubricating composite core for smooth, quiet operation. We recommend the bushings for optimal on-road and off-road performance, delivering excellent handling with no compromises. Alternatively, the traditional ¾” chromoly rod ends offer a firmer, performance-driven connection for those prioritizing responsiveness and control in demanding off-road conditions. The rod ends also feature threaded adjustment sleeves, allowing precise camber and caster adjustments while the arms remain installed.\u003c\/p\u003e\n\u003cp\u003eBoth configurations are equipped with heavy-duty Probearing ball joints for long-lasting durability in harsh environments. These billet upper control arms are built for lasting performance and easy installation, making them an excellent upgrade for any vehicle.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAmount of Lift: Allows for 0-3.5” of lift\u003c\/li\u003e\n\u003cli\u003eTrack Width: Stock\u003c\/li\u003e\n\u003cli\u003eMaximum Backspacing: 4.75”\u003c\/li\u003e\n\u003cli\u003eMinimum Rim Size: 17”\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eControl Arm Material: 6061 aluminum\u003c\/li\u003e\n\u003cli\u003eBushing Option: Probearing SilentSpin (maintenance-free, self-lubricating)\u003c\/li\u003e\n\u003cli\u003eRod End Option: Probearing ¾” chromoly with adjustment sleeve\u003c\/li\u003e\n\u003cli\u003eBall Joints: Heavy-duty Probearing\u003c\/li\u003e\n\u003cli\u003eCamber\/Caster Adjustability: Yes\u003c\/li\u003e\n\u003cli\u003eRebuildable: Yes (all components are fully rebuildable or replaceable)\u003c\/li\u003e\n\u003cli\u003eWarranty: Limited lifetime warranty on arms, 1-year warranty on ball joints and bushings\/rod ends\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFitment:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003e2019–2025 Silverado 1500 2WD \/ 4WD Including ZR2\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003e2019–2025 Sierra 1500 2WD \/ 4WD Including AT4X\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dirt King","offers":[{"title":"Glod","offer_id":46772751138985,"sku":"DK-636923B-GD","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Black","offer_id":46772751171753,"sku":"DK-636923B-BLACK","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Clear","offer_id":46772751204521,"sku":"DK-636923B-CLEAR","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Blue","offer_id":46772751237289,"sku":"DK-636923B-BLUE","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Purple","offer_id":46772751270057,"sku":"DK-636923B-PURPLE","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Red","offer_id":46772751302825,"sku":"DK-636923B-RED","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Orange","offer_id":46772751335593,"sku":"DK-636923B-ORANGE","price":1449.0,"currency_code":"USD","in_stock":true},{"title":"Bronze","offer_id":46772751368361,"sku":"DK-636923B-BRONZE","price":1449.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/0403\/1913\/files\/dirt-king-19_-silverado-billet-upper-control-arms-gold-main_1400x_fd2fe333-7958-47f5-9788-3ebf157aecb2.webp?v=1769750436","url":"https:\/\/www.levelupsuspension.com\/products\/dirt-king-billet-upper-control-arm-silverado-zr2","provider":"Level Up Suspension","version":"1.0","type":"link"}
