I will not worry about the lack of extra shims. The pinion is 18 tooth so I think it is the newer RTR kit.

There are no sun or planetary gears in an SC10 diff, it is a bevel gear diff. There are bevel and spider gears. The traxxas diff is a planetary setup, completly different.

I love mine so far, stock tires sucked along with the rtr motor, now that it's got a Ace 1313, GTB, Express Motorspors 10.5 and m3 Bowties I'm loving it. I gave away the rtr radio the day I got the truck.

Honestly Im not sure what there really called, as this is the first diff of this type that I have owned.

I am sure the manual said sun and panetary gears, thought I dont have it in front of me. This is what I found on line though.

Differential: Sealed, planetary gear

Sounds like we have a similar electronics set up

I need to get track tires though. I bought Proline switch 2.2 tires and T4 rims for my 10T, for an all terrain type fun tire, and I thought about getting them for the track also, thought I am not sure they would do that well though.

Ususlly track conditions are un preped, clay with a light to medium dust, with the exception of race days.

So far on my other R/C's what I have been most happy with is Hole shots, though I havent found them for the sc10 yet.

I know that rear rims from the J82 / T4 conversion work in the rear, as they are off set enought to still fit under the body.

Do you know if there are any other standard 2.2 wheels that will fit properly under the body, that can use a standard 2.2 truck tire, rather than the sc style rims that come with the truck.

I need some suggestions. I have a box stock SC10 and it is extemely loose in the rear what changes would help this problem?

I know i could find my answer if i read through these hundred some pages but i didn't

i got mine all setup now minus the motor. The guy i bought it from said he rebuilt the diff but didn't put fluid in it. Is it important? Should i put fluid in it and also i hear everyone talking about shimming it. Do i have to do that and how?

goosebumps or bowties. once you change the tires, it will feel like a totally different truck.

i hate the type of hub of the rear, i have stripped 3 sets of rears. Can it be modified to fit slash type hex hubs?

The new wheels are better, less likely to strip.
If you have old wheels, fill the spaces next to the pin slots with an epoxy/JB Weld or put small set screws in the holes to beef up that area.

Would 3 degrees be too much for these trucks in the rear? 1.5 enough?

1 to 1.5 should be plenty, front and rear. 3 is way to much, IMO, as the tires are narrow.

I had the same questions, and they were answered about a page and a half ago.

Use the Ae black grease... & the shims are behind the pin that hold the outdrives...if its an early model the shims are to thin & will concave on you causing your gears to skip... call Ae & they will ship you some...they are now thicker to fix this problem

The SC10 comes with 3 degrees total already (1.5 per side). Most people have upped that to 4 or 5 degrees by using uprights with built in toe or chedda bobs hinge pin mount.

I found 1.5 and 3 uprights per side ...Ill try both and post what I think of each...
