This evens out the effects of shocks between the two axles. The axle spring seats serve as anchors for the springs, so they play a central role in this process.How tight should trailer shackle bolts be?
They should be torqued down tight, squeezing the steel sleeve between the shackle,so the bolt cannot rotate in the shackle. If there is no steel sleeve, the bolt should have a larger shank where it goes through the bushing, and a smaller thread to tighten completely.What is au bolt on a truck?

u-bolt diagram Regardless of the bend type, all U-bolts are measured in the same manner as shown here. The U-bolt size is given as Diameter(A) x Distance(B) x Leg Length(C).
