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" wheel to be installed on any vehicle with a 5 on 4.5" bolt pattern (example JK wheels on a TJ). They start as a 1.5" thick piece 6061 T6 aluminum. They are then machined and anodized black 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
