Used to attached a MOMO horn button to a MOMO steering wheel, the MOMO Horn Button Retaining Ring is compatible with all flush-fitting MOMO horn buttons that require a securing plate from the rear of the steering wheel. The retaining ring is fixed between the MOMO hub kit and steering wheel and allows the horn button to be safely secured in place.
*Please note: a retaining ring is included within all MOMO boss kits and some aftermarket kits.
