These bearings should fit into the frame fine, but depending on which cranks you have, might not be compatible with you current cranks.

Hello,

Yes the American BB is the correct size for the GT slammer 2010, however you will need to check what axle size you have. it will either be 19mm or 22mm.

yes it would as the khe comes with an usa bottom bracket but when you buy a three peice you most make sure you get one that comes with a 22mm alxe

No this would not work as the cups are for un-selead bearings and would not work with the sealed mid bearings.

sealed and unsealed bottom bearing cups are differant so you will have to make sure that your new three piece crank has 22mm axle

Hello,

Yes this bottom bracket will fit the frame however your axle size will need to be 22mm to fit this item.

this bottem bracket will not fit but and standered size bmx bottem bracket will fit, just make sure you get either 19 or 22mm cups check the axle on your crankd for the correct sizing.

Hello you need to know what bottom bracket your frame takes if it is US, Euro, or mid. This axle is 22mm.
