Hub bearing spacers

[DSPbuilt]

I came across these today. Never really heard of them. Do you guys have any experience or or knowledge about them seems pretty interesting. I saw a video and it seemed to spin a lot nicer, granted it was a dry bearing.

"Back in the day", some drag racers oiled rather than greased their front wheel bearings to reduce drag.

Obviously, any of these methods are for track use only, and oiled bearings were serviced after each event.

Semi steer hubs and trailer hubs are oil filled (at least they are on the T880 I drive), far as the spacer go's, part of me says for what it cost it's not needed. Although if you over tighten the spindle nut, it will create drag like a brake. As long as you do it properly I really don't see the benefits. But I drive my Regal about 1000-1300 miles a year.

Seems like something that would make almost zero real world difference. The advantage to me would be that you can more quickly pull the hub apart and reassemble it.

Then it begs the question of why not just use the newer GM knuckles that take unit bearings? They probably weigh less even than the typical spindle setup.

Oiled hubs are a thing in many applications. Nearly every full float truck axle technically uses an oiled hub, although you'll find people like to assemble them with grease anyway. The downside to oil is the seals and sealing surface need to be better, and if the hub is oiled independently then the oil level must be checked and serviced on a regular basis. Bearings prefer oil over grease; grease is a compromise to make up for poor oiling design, sealing issues, or lack/cost of servicing options.

These are the kind of items used in F.A.S.T., Coyote Stock, Super Stock racing. Some refer to them as rainbow chasers. Alot of money spent for a little gain. Good options for a limited class.
Think of it like gun drilled axles or emptying the glove box. Sure the car will be faster but the gain will be so little, it's hard to measure.

Don’t lump gun drilled axles as rainbow chasing. They aren’t gun drilled for a weight savings, but that is an added benefit.

I thinking if it will benefit more for lateral forces say autocross/ road racing/ mountain carving and such.

Huh, that's interesting. 1200%, eh? How does one measure that exactly?

What is the term for spend alot for a little gain? Is rainbow chasing the wrong word?
To me it means to go after something that isn't really there.

Since the outer diameter of an axle carries more than 80% of the load. Class racers will remove the weight in hopes of reducing et but they all know the axle is not going to be as strong.

Not my opinion but quoted from Strange and Mark Williams.
