And Mopar installed millions of the tapered bearings over the years and had fewer problems. Just simple maintenance. You can always go back to factory when you want.

I asked Cass at Dr Differential about it last year before I bought them. His response was "I sell 4,000 Green bearings a year and I rarely see any problems"  In fairness to the haters, it sounds like there were some early problems that have since been overcome. Some really good info here..   http://www.doctordiff.com/blog/tech-info/why-green-bearings/
It's not a mater of hating. They just aren't as strong. It's the design of the bearing. Good enough for most of these cars that don't get driven enough, but to consider it an 'upgrade'? well, it's just not.

No, they are not an upgrade, but are a necessity for rear disc conversions.  It is what it is if you don't want to be limited to 11" drums.

I do think the weaker design of the Green bearings are highly exaggerated.  Straight roller and ball bearing rear axle bearings have been OE on FAR more vehicles than adjustable tapered rollers have been (in cars at least) and you don't see many failures on them, period.  Can it happen?  Sure.  Tapered rollers that are incorrectly lubed or adjusted can do the same too.  You're not going to be plagued with wheel bearing failures from running them just because you switched though.

I am running 12" rear disc brakes from Dr Diff using factory taper bearing. There are options. Easy to adjust the factory taper bearing too.

Unless you are auto crossing your car, rear disc brakes are just eye candy.
Since the front brakes do at least 75-80% of the braking rear drums are more than adequate.
In over 30 + years in the auto service/repair business and thousands of brake services on all makes of vehicles including trucks, the normal brake life was 2-3 sets of front pads to one rear brake shoe replacement.
If you really want to upgrade your braking, focus on the front brakes.
Go with floating multi piston calipers and larger, higher grade rotors and brake hoses.
Change your brake fluid regularly, more often if you tend to overheat your brakes a lot.
Most peoples experience with brakes, bearings and so on are with a very limited amount of vehicles if they even know how to service a vehicle.
Easy to say "yeah this or that works fine" These people are just talking from what they hear or read. Not what they know.
Think about it. If they really knew what they were talking about, they wouldn't be asking questions about it on these websites.

:iagree:  Same here, except mine are the smaller kit, 10 1/2" I think it was.

I had a buddy that installed new " green bearings" on his circle track car , put him on the trailer early, didn't last the night.

By technical design, the tapered axle bearings are superior to non-tapered bearings.  I've spoken with industry engineers about the matter.  Non-tapered has less life-span, especially when side-loads are being increased at anytime (autocrossing, etc).

Dr. Diff offers at least two rear disc setups that can use either bearing design.... he's done his homework!
