Correct-Length U-Bolts for Leaf-Lifted 80-97 F-250 Trucks

Adding leaf springs or add-a-leafs to a 1980-1997 Ford F-250 4WD raises the spring pack height, which requires longer u-bolts to properly clamp the axle. Tuff Country's 27851 kit supplies zinc plated u-bolts sized for that taller spring pack.

Key Features

  • Sized for vehicles lifted with springs or add-a-leafs
  • Zinc plated for corrosion resistance
  • Includes nuts and washers for a complete install
  • 5/8 in. bolt diameter, 3 5/8 in. inside diameter, 14 1/2 in. length
