Do u know if there is a difference between the sc10 diff and a b4 diff? Kind of confusing, they have different part numbers, but I have seen some docs that say they are interchangeable and others that say they are not

I think the only difference is the Ball diff has thinner drive cups and the Gear has slightly beefier ones, I know there is a difference in the diff case cause I've built a few loaner cars for our kids program. B4/T4 and SC10 but they are all interchangeable if the diff fits the case.

I was meaning between the sc10 ball diff and b4 ball diff, not gear vs ball. Not sure if u or anyone has compared them.

Thx for the help

The outdrives for an sc10 have shoulders on them to make it possible to interchange a gear diff, so it will not fit in a B4 gearcase.

Kind of true. The sc10 was the first to incorporate a ball diff in an ae vehicle with the metric bearings. The T4.1 and B4.1 also have the metric bearings, and hence have a different tranny case to accomodate them. If you have a diff from an sc10, t4.1 or b4.1 they will all be the same. First gen b4 and t4 diffs are different and take standard bearings.

You want the diff for the sc10, B4.1 or T4.1 with the metric outdrive bearings. All you need is the diff and some shims to get rid of side to side play. You want this diff

They wear, but not enough for me to think they are an issue. His original car is on its 3rd set of outdrives since the car first came out. The second car is on its 2nd set, and really only got replaced because I did full teardowns when we got the cf chassis. Sure, outdrives that never wear out would be great, but we get about the same life out of them as I did on my stock sc10, so I'm satisfied with them.

this is how mine and 2 others at my track are wearing. Maybe it is our track, but I don't think this is what I would call normal?

That looks pretty bad, my 2 previous sets and current outdrives only wear out on one side ever. The reverse side, never the forward side. Too much braking with my driving style maybe?

Crazy idea I tried in my car this morning while replacing my worn out chassis. I noticed that the top front bulkhead thing had empty area. So I thought I could place my transponder inside of it. The nice part is there's a small gap from where the top meets the bottom bulkhead that leaves space for the wire to run through. I opened up my MRT transponder case, took the chip and placed it inside. Unfortunately it happens to stick out the slightest bit, so I took my dremel and made a small notch in the bottom bulkhead where the chip would sit when both pieces come together. Everything is set now and hope to try it out on the track in the next couple days, should be worth a couple tenths of a second on my lap times. At least I hope so

Do you flip them? I've never seen one wear on both sides like that. Ours look about like that by the time I replace them, but that's with quite a bit of runtime on it too. How long until it wears like that? And what's your track like?

Default Wear

Never flip them. Track is med bite clay(Ocrc). Time is hard to tell because it really matters on how many packs. I would say probably in the area of 20 packs.

My originals did the same thing in 20 or less packs. Running 8.5 on a track similar to ocrc also.

Think you have to count them as consumables along with:
ball cups
drive shaft pins
slipper pads
spur gears
bearings
plastic hexes
wings
towers

Check your drive pins as well and get nice new ones. I replaced the ones in my gear diff and ended up turning my drive pins 90 instead of replacing them. But Im watching them a little more closely now
