2 1/2 spacers damage rear wheel bearings?

Hi, I was looking at some Z06 18 rims that will require 2 1/2 inch spacers all the way around. I read somewhere that spacers cause rear wheel bearing damage rather fast. Does anyone have experience with this? I have an 1981 vette, thanks jim

I have not seen any proof of that statement with quality wheel adapters installed.

I have seen rear wheel bearings go bad = new-old..It doesn't really matter.

Might they go bad right after installing adapters????? Maybe - but who is to know.

I have been running quality adapters on several cars for years with no issues.

I'm not one that likes spacers, But they are no different than changing the back spacing on your rims. As long as they are quality spacers and have the strength to hold the forces acting upon them... just my 2 cents.

I can't tell if I'm dealing well with life these days or I just don't give a shit any more.

I'm with iburke here. Not a fan of spacers. I've got a pair of 5/16 spacers on the rear of my car just to get the tires to clear the park brake cable. They've been on the car since '74 with no problems. I just got a new set of wheels and moved the backspace enough I can toss the spacers.

I drew a picture of the centerline of the wheel bearings and then started moving the backspacing around. I'm no bearing engineer, but it looked like to load the bearings really bad you need to go a long way-- over what most everyone is going to use as spacers.

Horsepower is like potato chips. If you have 300, you want 500. If you have 500, you want 800. One is never enough.

Adapters should not be a problem. We put a 1.75 inch adapter on a C4 without any problems.

Eckler's has a wide range of wheel adapters.

As far as the bearing are concerned, as long as you are putting a wheel with a positive offset they should do fine. A overly negative offset wheel is tough on the bearings.
