Tuff Country 97057 Block & Ubolt Kit - 4" (H) x 3" (W) x 4 3/4" (L) Tapered

The Tuff Country 97057 Block & U-Bolt Kit provides a bolt-on 4" rear lift for Ford Excursion 4WD, delivering a stronger stance and improved ground clearance while preserving ride quality. Built for reliability, it’s designed to be a straightforward, no-fuss upgrade for rear suspension.

• Lift height: 4" rear lift blocks (4" H x 3" W x 4 3/4" L); actual lift varies depending on the size of your factory blocks.
• Block material: Heavy-duty lift blocks crafted from cast iron with a tapered design to help minimize driveline vibration.
• Tapered design: Blocks are shaped to reduce driveline issues and maintain a smoother, factory-like ride.
• U-bolts: Extended zinc-plated rear U-bolts designed specifically for the Ford Excursion; 5/8" x 3 5/8" x 14 1/2" and intended to replace factory U-bolts (not long enough to stack blocks).
• Installation: Simple bolt-on installation for rear axles only; careful alignment with the springs and axle is recommended; may require extended length shocks for lifts of 2" or taller.
• Block options: Kits may include CAST BLOCKS or ALUMINUM BLOCKS depending on production batch; this kit is specified with cast blocks.
• Finish and durability: Zinc-plated hardware provides corrosion resistance for long-term performance in harsh conditions.
• Vehicle fitment: Designed to work with a range of Ford trucks (rear leaf-spring setups), including 2000–2005 Ford Excursion 4WD and related F-Series 4WD models from 1980–2016.

The 4" tapered rear blocks lift the vehicle while keeping a factory-like ride, making it a practical upgrade for towing, hauling, or simply achieving a more balanced stance. The kit’s design emphasizes durability and reliability with cast-iron blocks and corrosion-resistant U-bolts, ensuring you can handle daily driving and light off-road use without compromising integrity. Remember to verify your factory block size to anticipate the actual lift, and plan for extended shocks if your setup requires it.
