Anyone know what the size of the LSK's rear bearing? Is it the same as the Cobra and Mamba? I wanna replace my bearings because I think they're shot. But I need to know what size they are. Thanks in advance!

speed metal

It is not the same size. It is 25 X 14 X 5 .

Axe Part number is 8221 .

Thats correct its a different bearing to the later engines.
Try and get the Axe p/n as its a high speed bearing.
I matched up bearings before but they didnt hold up as well as the Axe one.
