Inner Axle Housing Seal

Are not the Green bearings weaker on side load and not as desirable as
stock bearings for a street driver?
That is what I heard years ago.
I run them on the race cars and never had an incident and no seal.
Technically, yes, but I think it is a mote point. There are many rear axles that use a "ball" bearing as OEM. Just as there are many rears that use a flat roller bearing that rides on the raw axle shaft, and has no resistance to side loading (uses the bearings on the carrier)
