Show original supplier description
The SuspensionMAXX SMX-184010 is a heavy-duty rear block and U-bolt kit engineered to provide a 1-inch increase in rear suspension height for the 2007-2019 Toyota Tundra 4x4. This kit is ideal for leveling the vehicle's stance, accommodating larger wheels and tires, or compensating for the sag caused by heavy loads like campers. It is constructed from durable steel blocks, high-strength Grade 8 U-bolts, tall nuts, and extra-thick washers, ensuring longevity and resistance to compression. Installation is designed to be straightforward, typically taking about 1.5 hours with job-specific tools. The kit requires no extensive modifications to the vehicle and is completely reversible, allowing for a return to stock specifications if needed. SuspensionMAXX also provides technical support for installation. The kit includes all necessary hardware. SuspensionMAXX products are 100% American-made and come with a MAXX Structural Lifetime Warranty.
