Whatever the case maybe we have you covered at Rough Country. Upgrade your rear suspension with Rough Country's vehicle-specific block and u-bolt kit!\u003cbr\u003eRough Country's rear block and u-bolt kits provide a simple remedy to an age-old problem that simply happens over the span of your vehicle lift. Each kit offers two rear blocks that are tapered to reduce driveline angles, and are much stronger than the standard cast block option. These heavy-duty replacements feature a single pin measuring in a 9\/16-inch to snuggle fit into your factory axle pad. Also included is a set of e-coated corrosion-resistant steel u-bolts. Our u-bolts offer four inches of thread ensuring that you have plenty of length to securely install this kit to the rear of your vehicle in no time flat.\u003cbr\u003eBest of all, Rough Country's vehicle-specific kits are backed by Rough Country's Satisfaction Guarantee!\u003c\/p\u003e\n\n\u003ch4\u003eFeatures\u003c\/h4\u003e\n\u003cp\u003eBlocks\u003cbr\u003eTapered to reduce drive shaft angle.\u003cbr\u003eSingle 9\/16-inch pin blocks.\u003cbr\u003e2.5-inches wide.\u003cbr\u003eU-bolts\u003cbr\u003eThread Size: 9\/16-inch\u003cbr\u003eInside Width: 2.5-inch\u003cbr\u003eInside Length: 10.5-inch\u003cbr\u003eStyle: Square\u003cbr\u003eE-coated black\u003cbr\u003eCorrosion resistant\u003c\/p\u003e\n\n\u003ch4\u003eNotes\u003c\/h4\u003e\n\u003cp\u003eDoes NOT fit models with equipped with composite leaf springs.\u003c\/p\u003e\n\n\u003c!-- KAOS_RC_RUNDOWN_START --\u003e\n\u003chr\u003e\n\u003ch3\u003eThe Kaos Run Down\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eFitment Year:\u003c\/strong\u003e 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 2016 2017 2018 2019 2020 2021 2022 2023 2024 2025\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMake:\u003c\/strong\u003e GMC\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eModel:\u003c\/strong\u003e Sierra 1500\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSubmodel:\u003c\/strong\u003e AT4\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDrive:\u003c\/strong\u003e 4WD\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstall Time:\u003c\/strong\u003e 2 - 3 hours\u003c\/p\u003e\n\u003c!-- KAOS_RC_RUNDOWN_END --\u003e\n\u003c!-- KAOS_SKU_SEARCH_START --\u003e\n\u003cdiv class=\"kaos-sku-search\"\u003e\n\u003cp\u003e\u003cstrong\u003eManufacturer SKU:\u003c\/strong\u003e 6521\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!-- KAOS_SKU_SEARCH_END --\u003e","brand":"Rough Country","offers":[{"title":"Default Title","offer_id":53969431888156,"sku":"RC-6521","price":79.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/0142\/7228\/files\/2_5in-block-u-bolt-6521.jpg?v=1772977841","url":"https:\/\/kaosor.com\/products\/rc-6521","provider":"Kaos Offroad","version":"1.0","type":"link"}
