The details behind the work.
Questions about this service.
Direct answers help confirm whether the unit and requested work belong at Standard HiRail.
Can you make U bolts for a HiRail truck?
Yes, for supported vehicle applications. We confirm the U bolt shape, diameter, inside width, length, thread and surrounding axle and spring arrangement first.
Should U bolts be reused after spring work?
The existing fasteners must be inspected against the repair procedure and condition of the assembly. New correctly sized U bolts are commonly part of spring work when reuse is not appropriate.
Talk through the u bolts and hardware concern.
