The newer BB26 part on SRX accommodates that 251mm wheelbase on the TT02 S type chassis. This was previously not an option with the original BB26 (54634)

I changed my 419XR from the original arms to the 420 arms when they initially came out. While the shape of the 420 arms are different, they have no effect to on wheelbase.

I also just installed the 420 arms on my TT02S.. with the original 54634 suspension mounts with no changes in wheelbase.
