Mishimoto Borne Off-Road wheel adapters convert an 8x180 hub to the 8x165.1 (8x6.5) bolt pattern, so earlier 8x6.5 wheels can be mounted, while adding track width and brake clearance. Each 1.5 in (38.1mm) adapter is forged from 6061-T6 aluminum with a hub-centric design that acts as a direct extension of the axle hub for precise fitment and reduced load on the hardware. Pre-installed grade 12.9 steel M14x1.5 studs and matching lug nuts are included, and a black anodized finish resists corrosion. The kit contains two adapters and is covered by the Borne Lifetime Limited Warranty.
