Hey everybody, sorry to make a new thread for this but I haven't been able to find a direct answer to my question despite a LOT of looking.

What I'd like to know is which rear arm for the 2wd slash is longer. The rpm rustler rear arm,which I know is 102.5mm(or 4.04") in overall length, or the rear slash 4wd protrac arm(I haven't been able to find it's dimensions). On a side note, does anyone know if I run either of these two if they'll overextend the driveshafts? because I know with the rustler arms I'll need new toe links.

Any input is appreciated. Thanks
