That is about the same amount of weight that I managed to lighten by hole drilling my MIP CVD Dog Bones and Axles.



OK, not really, but I would like to see someone try. That would be so hard to do right.

Associated and Kimbrough have 69T, 48dp.

I believe that AE now has Kimbrough make their spurs - nowadays they look exactly alike

Robinson Racing Products (RRP) also has excellent machined spurs, very precise....

There are a few others out there with unusual sizes, e.g. for oval racing where they need really high gears.

How does one use other spur gears? I have a baggy with about 20 of them, but they don't have that Octogonal shape for the the clutch material and the hole in the center is about pencil sized.

Just buy Losi ones, or cut your own out of Associated Slipper material.

Sorry not sure what you mean about all that ... I actually have a T3 but these all worked fine for me .... I thought the T4 was the same....

The T4 spur gears have an octagon shape molded in the center that helps keep the slipper plads from moving.

Grr. What is needed for a complete diff rebuild? Any tips? Thought that it was the slipper clutch, but made the noise when I had the truck off the ground! What is the best way to remove the diff from the truck?

got a few questions. first what kinda speed should i expect out of a 19t geared at 19/87(komodo or putnam)? also why does it seem like my rustler was faster i ran the same set up in it? this is getting annoying with all this motor crap i think im goin to get a mm5700 and say screw it all. though i have to run a 19t on the off road track i race at and a 27t indoor in the winter.

Had a great time tonight, just doing some bashing with new Traxxas Rustler and a brand new Losi XXXT brushless. I could use some new tires, and have have some coming, but I could nearly hold my own with the Brushless XXXT and was a third to a half a lap faster than the traxxas. As far as motors, I was out gunned running only a 27 turn Monster Horsepower stock.

What can one do to keep the back end from getting really loose?

Get my new tires and speed control this week.

AE makes a diff rebuild kit. Its about 8 bucks, and comes with everything you need except the diff balls. parts Here you can see all of the diff parts, and the first item is the rebuild kit. Remember, the diff in the t4 is the same diff thats in the b4, gt, and gt2.

I can guarantee you that those are for electric Touring Cars. Take a picture of one and post it.

Tires are 90% of your setup so post the kind of dirt your running on and we can help you out.

Thank you! I kept looking up 7677 and getting the GT rebuild kit and didn't know if that was it.
