Mount this pair to your 4x4.25" (4x108mm) hub to run 4x100mm wheels. Seat each adapter flush against a clean hub face, torque the fasteners to your vehicle's factory specification using the torque reference chart, then re-torque after 50 to 100 miles. Factory studs that reach past the adapter face must be shortened so the wheel seats flush. Free US shipping.
Common questions
Are wheel adapters safe?
Yes, when seated flat on a clean hub, torqued to spec, re-torqued after a short first drive, and running full stud and thread engagement.
How do I confirm my hub is 4x4.25 inch?
Measure the bolt circle across your four studs; 4x4.25 inch equals 4x108mm, matching the applications shown in the description above.
