These Rear Block Kits include two (2) 3\" Rear Blocks, four (4) E-Coated U-Bolts, eight (8) Nuts and Washers and will safely lift the rear of your truck an additional 1\" to 3\" depending on the application. Based on OEM designs and never made out of light weight extrusions, our 3\" GM Blocks are made from cast iron and have anti-rotation ears built-in. Fits 1999-2021 classic and current body style 6-lug model GM trucks. Models with 1.25\" OEM blocks will want to take advantage of the additional 1.75\" of lift for towing and hauling, particularly when using a front leveling kit. 1999-2006 4WD trucks will replace the factory 2\" block for 1\" of additional lift. This kit eliminates the dangers of having to stack blocks which may be illegal in some states. ReadyLIFT Block Kits will put a slight rake back in your truck for hauling or towing and are designed to work in concert with your ReadyLIFT Suspension Leveling Kit. Like all ReadyLIFT products, these block kits come with our Lifetime Warranty. Installation time is approximately 1.8 hours. Note: 2019-UP models may need to trim off excess bolt length after installation. NOTE: This GM 1500 kit is NOT COMPATIBLE with vehicles equipped with rear composite mono-leaf springs. The mono-leaf is easily identifiable   the U-bolt is round\/circular around the top of the leaf spring. This kit only works with vehicle equipped with traditional steel leaf springs   identified by   square    U-bolts.\n\u003cp\u003eUpgrade your GM or Chevy 1500 truck with the ReadyLift 66-3003 OEM-Style Rear Block Kit, designed for models from 1999 through 2022. Crafted from durable cast iron, these 3-inch lift blocks are engineered to provide a safe and reliable method to increase rear height by 1 to 3 inches, depending on the application. The kit includes two heavy-duty rear blocks, four E-coated U-bolts, along with nuts and washers, ensuring a secure fit and long-lasting performance. These blocks are built with anti-rotation ears to prevent shifting, maintaining vehicle stability during towing or hauling. Compatible with both 2WD and 4WD models, this kit replaces the original factory 2-inch blocks on 1999-2006 trucks for an extra inch of lift and can accommodate OEM 1.25-inch blocks with additional lift benefits, especially when used with a front leveling kit. Installation typically takes approximately 1 hour and is recommended to be performed by a professional due to the difficulty level. The blocks are finished in black, matching your vehicle's aesthetics, and are designed to work seamlessly with ReadyLIFT suspension leveling kits to achieve an even stance and improved load capacity.\u003cbr\u003eThis product is intended for use on vehicles equipped with traditional steel leaf springs, identifiable by square U-bolts. It is not compatible with rear mono-leaf springs featuring round U-bolts, which are common on some models. Please note that vehicles with rear composite mono-leaf springs should not use this kit to avoid potential fitment issues. As with all ReadyLift products, this kit comes with a lifetime warranty, ensuring peace of mind with your suspension upgrade. Proper installation may involve trimming bolt lengths on newer models, specifically 2019 and later, to ensure a perfect fit. This lift kit is ideal for drivers seeking increased ground clearance for towing, hauling, or off-road adventures, providing a slight rake that enhances vehicle appearance and functionality. For safety and compliance, always consider local regulations regarding block stacking, which may be illegal in some areas.\u003cbr\u003eEnsure your truck's compatibility before installation and consult a professional installer to achieve optimal results, safety, and vehicle performance.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCast iron construction for durability and safety\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes two 3-inch rear lift blocks for 1 to 3 inches of lift\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eAnti-rotation ears built-in to prevent shifting during use\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eE-coated U-bolts for corrosion resistance and secure fit\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCompatible with 1999-2022 GM\/Chevy 1500 models, including 2WD and 4WD\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned to replace factory 2-inch blocks on earlier models for added lift\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eInstallation requires professional expertise and approximately 1 hour\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFinished in black for a seamless appearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eNot compatible with rear mono-leaf springs with round U-bolts\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes nuts and washers for complete installation\u003c\/li\u003e\u003c\/ul\u003e\u003cbr\u003e\nFitment:\u003cbr\u003e\nChevrolet Silverado 1500  1999\u003cbr\u003e\nChevrolet Silverado 1500  2000\u003cbr\u003e\nChevrolet Silverado 1500  2001\u003cbr\u003e\nChevrolet Silverado 1500  2002\u003cbr\u003e\nChevrolet Silverado 1500  2003\u003cbr\u003e\nChevrolet Silverado 1500  2004\u003cbr\u003e\nChevrolet Silverado 1500  2005\u003cbr\u003e\nChevrolet Silverado 1500  2006\u003cbr\u003e\nChevrolet Silverado 1500  2007\u003cbr\u003e\nChevrolet Silverado 1500  2008\u003cbr\u003e\nChevrolet Silverado 1500  2009\u003cbr\u003e\nChevrolet Silverado 1500  2010\u003cbr\u003e\nChevrolet Silverado 1500  2011\u003cbr\u003e\nChevrolet Silverado 1500  2012\u003cbr\u003e\nChevrolet Silverado 1500  2013\u003cbr\u003e\nChevrolet Silverado 1500  2014\u003cbr\u003e\nChevrolet Silverado 1500  2015\u003cbr\u003e\nChevrolet Silverado 1500  2016\u003cbr\u003e\nChevrolet Silverado 1500  2017\u003cbr\u003e\nChevrolet Silverado 1500  2018\u003cbr\u003e\nChevrolet Silverado 1500  2019\u003cbr\u003e\nChevrolet Silverado 1500  2020\u003cbr\u003e\nChevrolet Silverado 1500  2021\u003cbr\u003e\nChevrolet Silverado 1500  2022\u003cbr\u003e\nChevrolet Silverado 1500  2023\u003cbr\u003e\nChevrolet Silverado 1500  2024\u003cbr\u003e\nChevrolet Silverado 1500 Classic  2007\u003cbr\u003e\nChevrolet Silverado 1500 HD  2001\u003cbr\u003e\nChevrolet Silverado 1500 HD  2002\u003cbr\u003e\nChevrolet Silverado 1500 HD  2003\u003cbr\u003e\nChevrolet Silverado 1500 HD  2005\u003cbr\u003e\nChevrolet Silverado 1500 HD  2006\u003cbr\u003e\nChevrolet Silverado 1500 HD Classic  2007\u003cbr\u003e\nChevrolet Silverado 1500 LD  2019\u003cbr\u003e\nChevrolet Silverado 1500 LTD  2022\u003cbr\u003e\nGMC Sierra 1500  1999\u003cbr\u003e\nGMC Sierra 1500  2000\u003cbr\u003e\nGMC Sierra 1500  2001\u003cbr\u003e\nGMC Sierra 1500  2002\u003cbr\u003e\nGMC Sierra 1500  2003\u003cbr\u003e\nGMC Sierra 1500  2004\u003cbr\u003e\nGMC Sierra 1500  2005\u003cbr\u003e\nGMC Sierra 1500  2006\u003cbr\u003e\nGMC Sierra 1500  2007\u003cbr\u003e\nGMC Sierra 1500  2008\u003cbr\u003e\nGMC Sierra 1500  2009\u003cbr\u003e\nGMC Sierra 1500  2010\u003cbr\u003e\nGMC Sierra 1500  2011\u003cbr\u003e\nGMC Sierra 1500  2012\u003cbr\u003e\nGMC Sierra 1500  2013\u003cbr\u003e\nGMC Sierra 1500  2014\u003cbr\u003e\nGMC Sierra 1500  2015\u003cbr\u003e\nGMC Sierra 1500  2016\u003cbr\u003e\nGMC Sierra 1500  2017\u003cbr\u003e\nGMC Sierra 1500  2018\u003cbr\u003e\nGMC Sierra 1500  2019\u003cbr\u003e\nGMC Sierra 1500  2020\u003cbr\u003e\nGMC Sierra 1500  2021\u003cbr\u003e\nGMC Sierra 1500  2022\u003cbr\u003e\nGMC Sierra 1500  2023\u003cbr\u003e\nGMC Sierra 1500  2024\u003cbr\u003e\nGMC Sierra 1500 Classic  2007","brand":"ReadyLift","offers":[{"title":"Default Title","offer_id":55991358193956,"sku":"663003","price":136.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0974\/0497\/7444\/files\/RL-3-REAR-BLOCK-KIT-CHEVY-GMC.png?v=1786051244","url":"https:\/\/kovaoffroad.com\/products\/readylift-66-3003-oem-style-rear-block-kit-for-1999-2022-gm-chevy-1500-trucks","provider":"Kova Offroad","version":"1.0","type":"link"}
