All planes with the LEAP's have the LRD.

What we are not being told is why this only affects the Max and not the neo's. Or could affect both just we haven't heard of any documented incidents of this occuring on the bus.

But I love flying the Max. Boeing absolutely does need to finally design a 737 replacement, but Max is a good flying bird overall. Really my biggest gripe with it vs an NG is the removal of the APU EGT gauge. Second gripe being how long it takes for the LEAP's to start, but that isn't a Max exclusive issue.
