For the large 8000 lb. springs you want to use U-Bolt Kit for Mounting 8,000-lb, Round Trailer Axles part # APUBR-35 and for the smaller 3500 lb. springs use the U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles part # APUBR-1. Thes will give you the u bolts, nuts and the new plates so you will be set.
