Tuff Country 97050 2-Inch Rear Block and U-Bolt Kit for 4WD Trucks with 4-Inch Axle

The Tuff Country 97050 is a 2-inch rear block and u-bolt kit engineered as a bolt-on lift solution for 4WD trucks equipped with a 4-inch rear axle. Designed and manufactured in the USA, this kit delivers a clean 2-inch rear lift while maintaining a factory-like ride quality.

How It Works:

Cast lift blocks are inserted between the factory rear leaf springs and the rear axle, raising the rear of the vehicle by 2 inches. Extended-length zinc-plated u-bolts replace the factory u-bolts to secure the assembly, providing a custom, application-specific fit.

Key Features:

• 2-inch rear lift — raises the rear end for a more level stance and improved tire clearance
• Heavy-duty cast iron lift blocks — non-tapered design for maximum stability
• Block dimensions: 2 in. H x 3 in. W x 5.75 in. L
• Extended zinc-plated u-bolts — corrosion-resistant and custom-fit for the application
• Dual-pinned block design — locating pins prevent axle shift under extreme loads
• Bolt-on installation — no cutting or welding required
• Made in the USA

What's Included:

• One pair of cast 2-inch lift blocks
• Extended-length zinc-plated u-bolts
• All required hardware

Installation Note: On most applications, factory-length shocks must be replaced with extended-length shocks when installing rear lift blocks 2 inches in height or taller. These blocks are designed for rear axle use only — never use lift blocks on a front axle.
