Not sure. What's the reason for changing the bearings? I would suggest that if your doin a bearing swap in a motor, opt for a better bearing like from Boca. The front main bearing in my Axial started leaking, so I dropped the extra $$ and got some Boca Bearings.

I want to replace all my bearings or just the rear bearing becouse its rusted and the engine wouldn't idle well. When i took it apart and spun it, it didn't spin very freely. I saw a kit from boca and it was an k4.6 kit and i couldn't find an f4.6 kit so i asked if it would fit.

Ok. I'm not sure if the sizes are the same or not. Did you try contacting Boca and asking them?
https://www.bocabearings.com/produc...del=NITRO STAR K4.6 W/PULLSTART&feature=4.6CC
so k4.6 rear 14.00 x 25.00 x 6.00 mm, front 7.00 x 19.00 x 6.00 mm
Measure your existing f4.6 bearings to compare, front ones are usually standard. I think the rear f4.6 maybe 14/25/6.
They can be pain getting out, usually need to heat it up in an oven.
Maybe easier to get a complete new crankcase with bearings on ebay.
