2017~2025 HELP!! Replaced Lower Arm is different from Original

[brent99]

I own a 2021 CE AWD(non-turbo). I had to replace the rear wheel and suspension due to a bad T'bone collusion. I think my original part number is probably KD35-28-300 and the replacement is probably KD35-28-300A(This was mentioned by the repair shop before the replacement).

The official mazda part mentions both parts but some parts store mentions that KD35-28-300A is not for AWD. The replaced part looks a little different from the original. please check the highlighted image that has mounting brackets(Maybe?). I want to make sure they used the right part.

1. LEFT Wheel Original

2. RIGHT Wheel Replaced

3. Difference on right

When parts in Mazda's system get a design revision, they add the "A" to the end of the number. I wouldn't think twice about the new arm not being exactly the same as the other side.

If the part ends up with a second revision, the part number will get a "B" at the end, and so on.

Got it. But what about the brackets? Is it possible to mess up the AWD system?

AS long as the hard points mount up, and the alignment can be brought into spec, you'll be fine.
