Hey Bruce,
As long as the thread pattern (1/2"-20) is the same you can go with a 13/16" outer diameter over the 7/8" lug nuts you currently have. We offer open-ended lug nuts # CE11051 or closed lug nuts # KALN1375S with this sizing. view full answer...
Hey Dave, it sounds like you are looking for a heavy duty shackle kit for your 2015 Premier Ultralite. For that your best option is the MORryde Upgrade Kit part # MR46ZR. This is a tandem axle shackle kit like you need that is the correct dimensions all around. It's for 1-3/4 inch wide leaf springs and the shackles are 2-1/4 inch from bolt hole center to bolt hole center like you need as well. view full answer...
Yes, if you'd like you can use the 30" Long 6-Leaf Double-Eye Spring for 5,000-lb Trailer Axles # UG34FR on your 3,500 lb axle. Your trailer will ride stiffer but it is certainly something you can do if you desire. view full answer...
