RT Off-Road's 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 blue for corrosion resistance. From there, grade 8 studes are pressed into the Adapters. Each set includes 2 Spacers, 10 Lug Nuts and Thread Locking Compound.
