After going back and forth and having a couple of other deals fall through I finally have my brand new Baker DD6 builders kit sitting in my living room. The unit was first shipped from Baker barely 5 months ago and I was fortunate enough to get it for $1500 plus shipping. I was expecting it to be shipped with a conventional inner race as shown on their site. However, mine arrived with one of their High Torque bearings. I'm not real familiar with them and don't know anyone who's used one. Have they been working okay or would I be better off with a standard race. Or maybe even something like the S&S race.

Baker high tq bearing is nothing more than a 6205 bearing with shield and the center honed out to slip fit the mainshaft.. I would take care in ensuring the bearing fit into the primary case as the fit can be tight. If too tight the bearing can bind and start slipping on the mainshaft.. Not good.. I've used sealed versions from BDL and Rivera that seem too work well on dry primaries but the baker on a 2000 dyna bound up and was removed.. It got replaced with a SnS ..   Not sure how they get away by saying the bearing is high TQ as it is only a 6205 bearing.. Roller supports more load.. But since the baker bearing is one piece, it can;t walk.. I would probably use a stock bearing or baker (after checking fit) unless the motor is real big then I'd use the SnS..

I had the Baker bearing like Max said, the bearing felt great before it was installed, but after installing the bearing it felt very rough while turning it.   it nothing but a 6205 bearing,  when i updated my inner primary to the 02-06 model on the 2000 T.C.  I got the shielded 6205 from Napa and hone the inside bore to fit the main shaft, but I also drilled a drain hole between the bearing and seal on the inner primary to drain any primary oil that could get between there back into the primary, and the bearing felt good installed.  have 20K plus miles on this set up and it works great for me on the big inch motor while before doing this, I would have IP seal leaks within 1000 miles multiple times with 3 different inner primary housings and the big inch motor.   as you can see in the picture the bearing is a 6205Z.

update:  with the IPB race being eliminated, the set up does require different seal,  I use a double lip seal from Fastenal 4190957 .  with the seal install flush with the inner primary, it will not interfere with drain hole.

A fresh stock bearing & the S&S race sleeve will keep things in line.

My initial plan had been to use the S&S race but since the bearing came with the kit I figured I ask around about it. I remember a few years back it was recommended to install a couple of snap rings to prevent the S&S race from being able to walk outward. Is that still recommended.

 The S&S is on there so tight, I've never seen one move, but even if it did, it has less than 1/8" to go to the back of the clutch hub, which should be solid.

  My choice.  You don't hear of any issues with the S&S race and stock roller.

Good information,I'm going to check my stuff out for my DD7...... 
I think I got Thier same bearing with my kit also !

Yes the DD7 comes with the one piece bearing if you use a different bearing then supplied it will have to be the older ipb and race because they used the older main shaft size (I don't remember the actual size) one the DD7

Good info to know.  as long as nobody has any issues,I will use what they sent with it,unless some one says something different...... 

I do know they also sent a race for the inner primary bearing also,I will assume it would be for the stock type IPB, I will check it out when I get back at it....... 

I actually had the race sitting on the main shaft getting ready to drive it on...... 
And glad I ran across this post,because the Race that the send along with the kit,if I'm reading this right isn't going to work with the Heavy Duty Bearing....... 

 
Stock bearing SS sleeve
Or if SS has the complete bearing and sleeve. 

I have been using  the baker high torque bearing for at least 20000 miles and as Max has said the fit is tight and when the bearing is not installed it rolls freely but when installed becomes rough when turning ,I have it out right now and it still seems good after 20000 miles,is there a way to take a little off of the outer diameter to loosen up the fit without taking it to a machine shop ?

Have been running the stock roller with the S&S race for a long time now with zero problems. I did try the ball bearing "upgrade" unsuccessfully. That being said you can get a ball bearing with a c3 or c4 suffix that has greater internal clearance and may work,as the standard 6205 bearing looses all of its internal clearance  after being pressed into the bore of the inner primary.  Although generally not a big fan of S&S, will say their inner primary bearing race was a cure to a real problem with stock Harley inner race walking in.

I've got over 20k on a DD7 with their bearing.  It was a tight fit in the inner primary and worried about it after warming up the case to get the bearing in and fearing it might crack.  Guess my fears are unfounded.  My thoughts were if the bearing ever did seize your output shaft would be toast because of the bearing riding directly on it instead of the stock race.  Time will tell.
