Tuff Country 97058 4-Inch Non-Tapered Rear Block & U-Bolt Lift Kit

The Tuff Country 97058 is a 4-inch non-tapered rear block and U-bolt kit designed as an economical and straightforward solution for lifting the rear end of select Ford trucks and SUVs. The kit works by inserting heavy-duty cast iron lift blocks between the factory rear leaf springs and the rear axle, effectively raising the vehicle's rear stance without requiring complex modifications.

Key Features:

• 4-Inch Lift Height: Non-tapered cast iron lift blocks provide a consistent, durable lift — actual lift achieved will vary based on the size of the vehicle's factory blocks
• Heavy-Duty Cast Iron Construction: Blocks are engineered for durable, consistent support under load
• Extended Zinc-Plated U-Bolts Included: Purpose-built U-bolts sized at 5/8" x 3-5/8" x 14-1/2" (round bend) replace the factory U-bolts for a secure, corrosion-resistant fit
• Rear Axle Application Only: Designed exclusively for rear axle use — lift blocks must never be used on a front axle
• Bolt-On Installation: Simple bolt-on design replaces factory blocks with no cutting or welding required
• Corrosion Resistance: Zinc plating on U-bolts provides long-lasting protection against rust and corrosion

Installation Notes:

• Actual lift achieved depends on the size of the factory blocks already installed on the vehicle — check factory block size before ordering
• U-bolts included are not designed for stacking blocks
• When installing rear lift blocks of 2 inches or taller, factory-length shock absorbers should be replaced with extended-length units to maintain proper ride quality

The Tuff Country 97058 block and U-bolt kit is an affordable, reliable way to add rear lift height and improve the stance of your truck. As part of Tuff Country's EZ-Ride Suspension lineup, this kit is built for durability and ease of installation.
