Correct-Length U-Bolts for Leaf-Lifted 79-85 Toyota Trucks
Adding leaf springs or add-a-leafs to a 1979-1985 Toyota 4WD truck raises the spring pack height, which requires longer u-bolts to properly clamp the axle. Tuff Country's 57750 kit supplies zinc plated u-bolts sized for that taller spring pack on this platform.
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
- Designed specifically for the 1979-1985 Toyota truck platform
