Thoughts... RC4wd.com's Heavy Duty R2 transmission in E-maxx??

[lincpimp]

The smaxx will not easily fit the new emaxx tranny. To do so you would need the new emaxx chassis, trans and center driveshafts. You can put an old emaxx tranny in there, but they are not the best stock, need steel idlers an the gmaxx single speed kit is good too but costs 70 bucks...

Thr stock ratio for the new tranny is 1.83:1 so the r2 tranny would be way low geared, so your truck would not go very fast. I would stick to the emaxx tranny if I were you.
