They are abec 7, wich means that the inner and outer diameters of the bearing are as close to spec as they can get. That doesn't make much of a difference in the belts, it made a difference in the amount of slop in the front and rear hubs. There is very little slop in them now.
I have to admit they do seem to create a little drag on the drivetrain. beacause they are packed with grease. The theory is that the grease keeps the dirt out of the bearing races hence they keep longer between rebuilds. Around here the tracks are made of grey clay that is very abrasive and hard on the cars, so the rubber seals and grease made me buy them. I only have 1 day with the car so far, so I don't know if its worth the extra money.
The red seal bearings that come with the kit are very similar to the boca. They are rubber sealed too, that look to be very good quality. I honestly didn't know that the kit came with this type bearing, I thought they came with the old syle metal shielded type, had I know I would not have bought the boca bearings.

diff outdrives, they are different, is the black of a more durable material?

will the sx2 diffs fit in the sx3, even though they are different? Just easier to swap over during a meet rather than a rebuild.

Yes. We've run them in Andy's car.

Just started the build. Got the center spur assembly done and it rotates freely but when the center belt is attached to the pulleys in the next step, the transmission seems to be a bit rough when rotating. Is this normal or is there something I can do to free it up?

Its definitely not the center assembly binding as I made sure when I installed it that it moved freely but as soon as the center belt was installed the rest of the pulleys it felt rough. Thanks for the feedback in advance guys.

Everytime I tightened down the ally bulk head the pulley shaft wouldnt roll free...So I just took everything apart and redid the whole step and now it runs smooth...who knows lol it was awkward but its like butter now. Just waitin on some diff grease and molly grease to continue the build. Very nice build so far Im really impressed.

diff grease comes with the kit, its the best you'll get from anywere,and axle grease is fine for metal gears

Ya but I needed some grease on hand for diff rebuilds etc...Got the whole rear belt and diff assembled now...Whats the remedy for the clicking noise when rotating the rear belt and diff? Some one said something about a spacer somewhere but where exactly?
