Question:
Correct me if I'm wrong, but the DE66AR kit has 1/2" lugs and the DE68AR has 9/16" lugs?

Hey Randy! The # DE66AR has 1/2" wheel bolts and the # DE68AR has 5/8" wheel bolts. Are you looking for a complete kit with a specific wheel bolt size? What is your axle capacity? The # DE66AR is also for 7k axles and the # DE68AR is for 8k.

Would the DE68YR be the correct item for the 7K, 9/16" studs ?

I bought and installed the de66ar on my fifth wheel trailer and love them. I am thinking about switching out my tires and wheels to 17.5 from the 16” that are on there. The delima is the lug size and everthing I’ve looked at uses 9/16 or 5/8. Can you tell me what my options would be? Thanks
