RT Off-Roads Wheel Adapter Kits are a perfect solution for anyone wanting to expand their wheel choice. They allow the use of any 5 on 5.5 inch wheel to be installed on any vehicle with a 5 on 4.5 inch bolt pattern. They start as a 1.5 inch thick piece 6061 T6 aluminum. They are then machined and anodized blue for corrosion resistance. From there, grade 8 studs are pressed into the Adapters. Each set includes 2 Spacers, 10 Lug Nuts and Thread Locking Compound.
