Description
Raises Your Truck’s Rear. If you often use your truck for hauling, equip it with this ReadyLIFT 1-Inch Rear Lift Block Kit for Factory Top Overloads. This kit helps raise your truck’s rear for about 1 inch, so it won’t drop or sag. Even if your truck bed is loaded with big and heavy cargo, your vehicle’s rear won’t hit the ground, keeping its rear-end components safe and intact.
Cast-Iron Rear Lift Blocks. This kit includes cast iron rear lift blocks. Compared to lightweight extrusions, these cast-iron types are much stronger, allowing them to effectively support the weight and load of your vehicle. As long as these rear lift blocks are subjected to normal and intended use, they won’t easily crack, bend, or break.
E-Coated and Longer U-Bolts. What’s great about this kit is that it comes with longer U-bolts. With a longer build, the U-bolts can match the new height of your truck, enabling them to provide improved handling characteristics. Furthermore, these components are applied with an e-coated finish to fortify their defenses against corrosive elements.
Bolt-On Installation. This rear lift block kit offers a simple bolt-on installation process. However, you need to have light to moderate mechanical skills to ensure the proper installation of each component. For your convenience, this kit comes with a manual that you can read to help you familiarize yourself with the installation steps.
Covered by a Lifetime Warranty. If your purchased item exhibits factory flaws or sustains early damages, you may return it since it is covered by a lifetime warranty. Once the damaged item has been inspected and verified, ReadyLIFT will repair it or provide a replacement based on their own discretion.
Application. This ReadyLIFT 1-Inch Rear Lift Block Kit for Factory Top Overloads is engineered to fit 2011-2019 GMC Sierra 3500 HD models.
