This is a pack of ten 8x16x5mm metal shielded "Speed" 1/8 wheel bearings. ProTek R/C "Speed" bearings are high quality steel/chrome bearings designed for the R/C racing enthusiast.
These 8x16x5 metal shielded bearings are the standard bearing for 1/8th scale off-road vehicles, both for internal bearings in the diff cases as well as external wheel bearings. We offer these in metal shielded versions as some racers prefer these over the rubber sealed bearings. Please check the manual that came with your vehicle for the correct size if you are not certain.
