I don't believe in the accuracy of that setup sheet, but even if they weren't, they used a multi-disc slipper. Also, the setup sheet was far from complete. A close look at the pictures shows one huge thing that isn't listed on the sheet....

Chris J,
Is there a reason for not using steel inserts where the outdrive go out of the diffs? My only gripe with the truck is that the copper wears quicker than I like, which causes leaking and wobbly outdrives. At least the diff cups are fairily cheap to buy.

For instance, and I just checked with my calipers, the outside of the copper insert one one of my diffs is 5.4mm, while the inside is 5.06mm. Because the outside is worn, the grease does not stay in, then the diff leaks. Then the wobble in the diff causes the pin to press and deform the shim underneath the sungear causing even worse leaking.

I have done this, and it does help. But I would think that steel whould be much more durable, especially in a high wear area.

I have had this happen with a single shim. Case would have about .010" wear but the shaft was fine. With the double shim and new cases I am not seeing the wear.....yet. Can't help but wonder if the case used a steel insert and a single shim if it would not then destroy the case and outdrive shaft.

Have you checked out Fastlapproducts.net lately? They have added new products. Everything looks pretty cool. I'll have to place an order.

Good question, except in my rc8, the diffs last forever. They have a single shim and have steel where the outdrive go into the diffs. I have had the same diff internals for 2yrs in my rc8e. Now the case itself wears out where the screws tighten down the two pieces, but the steel insert, and the outdrives do not wear.

Regardless of where a spacer is it all comes down to clamping force of the spring x friction surface. you can put 4mm of spacer it doesn't matter its simple mechanics. Maybe you lucked out and got a good spring that all of the kits should have had. I've spent plenty of time on the phone with AE been through 5 different local trucks 10 different new springs/ thrust spacer packages and non of them worked. by using a spacer all your doing is moving the components on the shaft outwards. your not increasing clamping load. The basket doesn't even increase clamping load that is all done by the spring. the basket just adds another friction surface.
In a perfect world you would want a super stiff spring but that would require a much larger dia. shaft. to hold the torque.
You should send your truck to AE because they seem to have to use a basket as well and your truck would be perfect specimen. I'm serious.
