    W/O Product Instruction

     

    Questions and answers：
    1. What is the material of the leaf spring?
    A: 60Si2Mn spring steel, surface thickening spray treatment.
    2. Can only one spring be replaced?
    A: Of course you can, but we strongly recommend replacing both springs at the same time, because the spring will sag and elongate over time. If it refers to replacing one, it is likely to not match the spring on the other side, which may cause the trailer to lose its level imbalance and disrupt your layout.
