Pick these up TODAY at my home in Elkhart, Indiana. “I have a pair of 6-5.5 TO 8-6.5 wheel
adapters”. This means you can bolt these adapters to your existing single 6 lug bolt hubs with a 5.5” bolt circle , to ACCEPT an 8 lug bolt single or DUAL wheel, with a 6.5” bolt circle. See pictures. I used them to convert a single to a rear dual wheel set up on the rear of a Chevy Silverado 1500. ~ Chrome flat face dual wheel lug nuts also available…These adapters can be used for other trucks also. Thanks for your interest
