Most (all) bearing kits will replace the races and bearings, #5, 20, 1, 2, 20, and 6.
Some kits require you to re-use the dust seal, #3. Other kits include a replacement seal.
Many (most?) bearing kits will replace the dust seal backing washer (#7) with a thicker spacer washer, as the stack height of roller bearings is usually different from the stack height of the original bearing setup. If you do a search on "bearing stack height" that should lead to some useful information about the spacers.
I like the All Balls steering bearing kits personally, as they include the seals and spacers.
