It is important to select the correct size for your vehicle in order for the Disklok to offer its full protection. Vehicle manufacturers often produce different sized steering wheels across their range and can periodically change them from year to year therefore we advise you to measure your wheel before purchase. The correct measurement should be taken across the centre line of the wheel from outside edge to outside edge.
Contact us if your chassis is not there. Or just measure your steering wheel carefully and order the correct size of the Disklok. 39, 41.5 and 44 are the maximum diameters, each has three positions there.
