OMP steering wheel hubs have been designed to maintain the original steering wheel position when a flat steering wheel is fitted. They fit onto the standard steering column to attach an aftermarket steering wheel. They have the common 6-bolt stud pattern as used by OMP, Sparco & Momo. OMP hub kits include bolts and fitting hardware where necessary but they do not include a horn button. They are vehicle specific and will only fit the exact application stated. If in doubt of the part number you need, please email us before purchase.
