I have these and wondered if these kits would fit a custom build up im working on. Mostly rustler aftermarket parts i think,all the parts have no label except the traxxas bags in multiple boxes i just received 2 days ago.So you guys are more up on traxxas so think these may work in a rustler tranny case?Id really like to get an alloy gpm tranny case for this project but no paypal.Has anyone got a pic of a gpm rustler chassis?don

#2520 will definitely fit the Rustler. You'll just need to drill a small access hole in the left trans case for adjustments.

#4420 I'm almost certain is for the Nitro Rustler. Same as the 2520 with the exception of the 32p diff gear.

Thats what i was thinking exactly since the 2520 comes with both the diff gears and i noticed ive got 4 metal idler gears too.
iI need to take some pics to find out what GPM PARTS I HAVE TOO.No labels on header cars and dont recognise them.says new 2002 and 2003 guess when they were made.don

The two diff gears in the 2520 diff are both 48p. One is for truck transmissions and the other is for buggy trans (TRX-1 and TRX-3).

Whats the scoop on the "old" ball diff that was in the eagle?
Is it any good?

I ran one that was in my eagle a long time...hard. Was a great basher and it never failed me. Only issue I had was getting the thing set where I wanted it. Was a fine line that was between too loose and too tight.

So the buggy diff gear will work in rustler or bandit and pede trans there all the same?don

Not exactly. The larger gear (60T) will work in the Rustler/Bandit/Stampede. Also the Blue Eagle line, SRT, Hawk2, and anything with the 2.72 trans.

The smaller gear (45T) will fit the TRX-1, TRX-3, and TCP buggies

ok thanks for the info.Need to go to sleep been at hospital with my daughter again since 130am don

Finally took some parts out the bag.Had to use two diff kits to make one complete,dang bags missing bunch small parts.I have a built tranny but its a used case,Still tryn find a new blue annoed GPM trans case and some kinda aluminum chassis to go with all the blue annord alloy front and rearend.aaarrrrrrgggggg!!!!and alloy bellcranks gpm to match!!!! don
