Hi,

is the rear subframe between BK and BL interchangeable? I hit mine and I cant find a reasonable used one for BK, same story for the rear trailing arms.

I looked at the other parts and the bushes, arms, bearing for the wheels are completely the same, selling even under the same part number. Struts and springs seem to be the same as well.



Anybody tried to replace BK Mazda 3 with BL parts subframe or rear trailing arms?

 

You really need to list your year MAZDA when asking question of a technical nature specifically about interchangeability in parts.

Better quality auto-dismantlers often have listing on known interchangeability of some parts between years and models of a specific platform.
