Expert Reply:
For 3,500 pound axle U-bolt kits like the Redline # APUBR-1 that use 1/2 inch hex nuts you will want to torque them down somewhere between 45 and 70 foot pounds. I have attached a great article on trailer suspension that includes this info along with details on all the other necessary components that you can look through.
