Product Details
Description
Raise the rear of your 2007–2021 Toyota Tundra 4WD with the Tuff Country 97077 Block & U-bolt Kit. This bolt-on kit delivers 3.5 inches of rear lift, giving you improved stance and clearance while maintaining a confident, controlled ride.
- Lift Height: 3.5" rear lift designed to increase ground clearance and create a more balanced rear profile.
- Block Construction: Aluminum lift blocks (kit variants may use aluminum or cast blocks) with a tapered design to help minimize driveline vibration and maintain smooth operation.
- U-bolts & Hardware: Extended zinc-plated U-bolts supplied to properly replace the factory hardware and secure the axle to the new blocks.
- Shocks Compatibility: In many installations, extended-length shocks are recommended when using blocks 2" or taller; check compatibility with your shock setup.
- Vehicle Fitment: Specifically engineered for the rear axle of the 2007–2021 Toyota Tundra 4WD.
- Installation: Simple bolt-on process—insert the lift blocks between the rear leaf springs and axle and bolt in the new U-bolts for a straightforward upgrade.
- Safety Note: Designed for rear-axle use only; never use lift blocks on the front axle.
The Tuff Country 97077 Block & U-bolt Kit combines durable aluminum blocks with precisely engineered U-bolts to deliver a reliable, easy-to-install rear lift. The tapered block design helps preserve driveline alignment and ride quality, while the corrosion-resistant hardware provides lasting durability in diverse conditions. Ideal for drivers seeking additional rear clearance, improved tire fitment, or a more balanced stance for towing and daily driving alike.
