The kit combines upper strut spacers, lower strut shims, a rear leaf spring block, u-bolts and shock extensions to provide a measured 3.5\" front rise and an effective 2\" rear rise on stock vehicles, creating a flush, factory-like appearance without extensive suspension rework.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit create a 3.5\" front lift from smaller parts?\u003c\/h3\u003e\n\u003cp\u003eThe front lift is the result of two matched components working with suspension geometry: a 2\" front spacer and a 1.5\" lower strut spacer. Though each part’s thickness measures less than its nominal lift due to shim geometry, together they achieve the advertised 3.5\" front raise while keeping mounting points and ride characteristics OEM-friendly.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eFront spacer adds 2.0\" nominal lift using a precise 1.4\" shim thickness\u003c\/li\u003e\n  \u003cli\u003eLower strut spacer contributes a 1.5\" nominal lift via a 0.8\" shim thickness\u003c\/li\u003e\n  \u003cli\u003eCombined geometry yields a true 3.5\" front increase on stock suspension\u003c\/li\u003e\n  \u003cli\u003eMaintains factory strut orientation and uses factory mounting locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill my original rear shocks still work after lifting the rear?\u003c\/h3\u003e\n\u003cp\u003eYes — when you lift the rear, your factory shocks may become too short to retain full travel.

This creates a 1.5\" front-to-rear difference that levels the truck’s factory rake for a balanced stance.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePackage rear block is 3\" but yields 2\" net lift when replacing a 1\" factory block\u003c\/li\u003e\n  \u003cli\u003eDesigned to pair with stock multi-leaf spring rear setups only\u003c\/li\u003e\n  \u003cli\u003eIncludes new u-bolts sized for the added block thickness\u003c\/li\u003e\n  \u003cli\u003eProduces an even look: front +3.5\" and rear +2\" on a stock vehicle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat materials and hardware are used, and will this affect durability?\u003c\/h3\u003e\n\u003cp\u003eFlexHitch builds the kit from 6061-T6 forged aircraft-grade aluminum with CNC machining for precision fit, and supplies Class 12.9 grade bolts to ensure clamp strength and longevity.

This kit is intended for Silverado 1500 and Sierra 1500 owners (2007–2018 models and 2019–2024 2WD models) who want a factory-friendly lift that levels the truck, increases ground clearance, and preserves OEM suspension components. It is not compatible with 2007 \"Classic\" trucks, ZR2, TrailBoss, Denali (2014–2018), AT4 or MagneRide models, nor is it suitable with aftermarket lifted shocks. For vehicles seeking lifts beyond 2–4 inches or for those with special suspension packages, consider vehicle-specific upper control arms and consult a qualified installer to ensure alignment and handling remain optimal.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does this kit fit ZR2, TrailBoss or Denali models?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. It does not fit ZR2, TrailBoss, 2007 \"Classic\", or 2014–2018 Denali models, nor MagneRide-equipped trucks.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Are the shock extensions compatible with aftermarket shocks?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. These shock extensions are designed only for OEM factory shocks, not aftermarket lifted shocks.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"FlexHitch","offers":[{"title":"Default Title","offer_id":48081867800734,"sku":"B0FC2BW3Y2","price":214.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0781\/2041\/9486\/files\/flexhitch-front-strut-spacers-packaging.jpg?v=1785809947","url":"https:\/\/northtrailauto.ca\/products\/flexhitch-3-5-front-3-rear-lift-kit-for-silverado-1500-sierra-1500-2007-2018-leveling-bolt-on-oem-compatible","provider":"North Trail Auto","version":"1.0","type":"link"}
