Is there any way to add bearing to Abu Garcia reels? 

I'm no expert but I believe most people would upgrade/add bearings and a carbon washer for the drag...maybe custom handle grips. That's the only things i know of but like i said, I'm no expert by any stretch. I'm sure other more knowledgeable people will chime in.

Honestly, it totally depends on the reel model and what you're trying to achieve by adding the bearings. More often than not, the difference in a 6 bearing reel and a 10 bearing reel is the fact that a company added 4 bearings (2 per) into the handle knobs. It honestly adds no performance upgrade but on paper, it makes it look better on paper. 

Depends on the reel. Maybe. I’d go a step further than @Brett’s_daddy and say all Abus should be upgraded to Carbontex. If the reel has HPCR Bearings, I would not upgrade them. IMO, these are the best bearings there are. The only bearings I’d upgrade on a reel with HPCRBB’s would be the spool bearings only, but it’s not needed. I agree with @fishballer06 I would not waste anything on adding bearings to the handle. I can’t feel any difference between bearings or bushings in the handles.

What kind of Abu reel? Do you want to add bearings or do you upgrade bearings?

Add bearings I have several ABUs I was just going to go through them and change them out if it was a benefit to do it.

Most of the Revo line already have carbon fiber drags.  I've found they respond really well to flushing with acetone and oiling with a quality oil like Bantam oil, Oust Metol, or TSI 321.
