I honestly wouldn't trust the GPM shocks as far as i could throw them. Had a set on my RC10GT. the Traxxas plastic bodies lasted the whole 8 years I had my old Stampede, and I beat the snot outta that thing:P

yeah, the rears for the Stampede/Rustler are the same length as the T-maxx's, the front shocks should be the length you need.
