SKF are about the best bearings that you can buy; this one is similar quality to the ones used by Volvo, so should easily last 160,000 miles like the original one did.
This is a full kit, so it includes the mounting bolts and all important hub centre bolt, as the original must not be re-used.
Do not confuse this with the cheap Chinese bearings that are being offered elsewhere, which will fail rapidly; this is much higher quality and can be trusted.
Remember that your life may depend on this safety critical part.
