This adapter bolts to your 6x5.5" hub so you can run 8x170mm wheels. Seat it flat against a clean hub, torque the fasteners to your vehicle's factory specification using the torque reference chart, and re-torque after the first 50 to 100 miles. If factory studs protrude past the adapter face, shorten them so the wheel seats flush.
