{"product_id":"2-inch-front-leveling-kit-w-upper-control-arms","title":"2-Inch Front Leveling Kit w\/ Upper Control Arms","description":"The ReadyLift 69-3920 SST Lift Kit is engineered to provide a 2-inch front lift and a 1-inch rear lift for the 2019-2023 GM AT4 and Trail Boss models. This kit is designed to work with the factory 2-inch front lift, incorporating a top mount strut spacer and a pre-load spacer to manage droop. It also includes heavy-duty tubular upper control arms featuring 1-ton ball joints and TCT pivot bushings for improved durability and corrected ball joint angles. The rear of the vehicle is addressed with 3-inch tall OE style cast iron lift blocks and rear bump stop extension cups.\n\nThis lift kit is specifically designed for AT4 and Trail Boss models and offers different maximum tire size recommendations for each: AT4 models can accommodate up to a 305\/55-20 tire on a 20x9 0 offset wheel, while Trail Boss models can fit up to a 295\/65-20 tire on a 20x9 0 offset wheel. It is important to note that AT4 and Trail Boss models have different front fender opening designs, affecting maximum tire fitment.\n\nExclusions for this kit include Sierra AT4X, Silverado ZR2 Edition, and vehicles equipped with rear composite mono-leaf springs (identified by round U-bolts). For 2024-2025 applications with round U-bolts, a separate U-bolt part number (67-35120UB) is required. The kit is not compatible with rear mono-leaf springs and use of the Auto 4 HI feature is not recommended.\n\nInstallation requires an alignment and may necessitate headlamp aim adjustment. If your vehicle is equipped with Advanced Driver Assistance Systems (ADAS), these systems will need to be checked and adjusted, potentially requiring OEM dealer service tools for recalibration. Estimated installation time is 4.5 hours, excluding alignment and wheel\/tire assembly.","brand":"ReadyLift","offers":[{"title":"Default Title","offer_id":52686297596216,"sku":"69-3920","price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687839552.jpg?v=1784871256","url":"https:\/\/store.motormia.co\/products\/2-inch-front-leveling-kit-w-upper-control-arms","provider":"MOTORMIA","version":"1.0","type":"link"}
