Some customers, including many racers and restoration purists, prefer Unipart branded products for known quality and tested reliability. This is the Unipart-packed genuine Timken-made rear taper roller wheel bearing set to fit all Minis except 13" wheel cars like MPi SportsPack model. For MPi, use GHK1805 set. Two sets required per car. The bearing sets now include an integrated spacer built into the inner race of each bearing, so no separate spacer is used.
Compared to the ball bearings at the rear of early Minis, the taper roller setup is stronger and much easier to remove for servicing.
For MPI Minis from about December 1995 on, see Timken set GHK1805.
