One base designation across loaded brands
Exact designations rank first. Dimensions, suffixes and other technical differences remain visible so the result is not mistaken for an interchangeability declaration.
“120” across 2 loaded brands
The base designation is shared, but the loaded boundary dimensions do not agree. Use Custom Compare when you want to choose exact suffix variants yourself.
