Spindle bearing spacer

I call bullshit. This "setup" has been in use for decades and decades. Can you spell "more than a century?" These setups WORK. All you need is a simple adjustment and proper lube and they go 10's of thousands of miles. In some cases 100K.

This design was also used for decades on front and rear axles of 4x4 pickups AND IS STILL IN USE on drive axles and steering and tag axles of heavy over the road trucks.

" More than a centery" Dang, I guess not.
Longevity is not the only factor considered when we hang parts on race cars. And it's still roller bearings. They didn't re-invent the wheel here. It's just a spacer between the inner bearing races that seems to have less drag according to my not so super sophisticated spin test. I wish I had better data to support the spacer. I am a skeptic at heart and most of the advertising is testimonials so maybe it is BS.
