U-BOLTS: ENSURING PROPER SUSPENSION FITMENT
U-bolt batches  

U-bolts are essential suspension components that secure leaf springs to the axle and help maintain vehicle stability under demanding conditions.

Despite their simple structure, U-bolts are exposed to heavy loads, constant vibrations, and daily wear. Choosing the right one is essential for suspension durability.

What should be checked?
  • Type/shape: round, square, or rolled, depending on the application
  • Correct diameter
  • Width between legs
  • Suitable length
  • Thread and pitch according to project specifications
  • Fastening points condition and proper torque checks
   Square U-bolt
Loose U-bolts can cause spring movement, leading to premature failure and safety risks.
