Tuff Country 97078 Block & Ubolt Kit - 1 1/2" (H) x 2" (W) x 5 1/2" (L) Tapered

The Tuff Country 97078 Block & U-Bolt Kit is a bolt-on rear lift solution for Toyota pickup enthusiasts who want a balanced stance and improved payload handling. It raises the rear by approximately 1.25 inches on Tacoma (1995–2023 4WD) and Tundra (1999–2021 4WD) models, without altering the front suspension.

• Rear lift height: 1.25" rear lift blocks to level the stance and accommodate heavier loads.
• Block material: Block blocks are available in aluminum or cast variants, depending on the kit batch; both are tapered to reduce driveline vibration.
• U-bolts and hardware: Zinc-plated extended rear U-bolts with matching nuts and washers for secure, corrosion-resistant mounting.
• Dimensions: Lift block size is 1.25" (H) x 2" (W) x 5 1/2" (L); U-bolts measure 9/16" x 2 9/16" x 9 5/8".
• Compatibility: Designed specifically for rear axles; suitable for 1995–2023 Toyota Tacoma 4WD and 1999–2021 Toyota Tundra 4WD.
• Installation: Simple bolt-on installation that relocates between the factory rear leaf springs and axle; no front-end modification required.
• Shocks note: For lifts of 2" or taller, factory shocks typically need to be replaced with extended-length shocks; see the Shock Absorbers guidance for details.

This kit delivers a reliable, consistent ride while enhancing rear geometry for better towing, cargo capacity, and on-road confidence. The tapered design helps minimize driveline vibration, preserving a comfortable daily drive even under heavier loads. Zinc-coated U-bolts deliver corrosion resistance for long-term durability, and the simple bolt-on approach means a straightforward installation with common tools. If you’re planning to run taller shocks, pairing this kit with extended-length shocks will help maintain full suspension travel and control across terrain.
