Hiya, yep they are the TOP Axle sleeves. they come as a set of 4, with 4 axle pins to. Use those pins when building up the driveshaft as they are about .5mm longer than the HB items, and fit nice and snug.
Im going to just smiply blow them through with motor spray after tonight and relube with Pedro's wax and that will be it, they are awesome !
