WEll the gears fit
 

I have the ue 6 spyder diffs. I want to swap out the pinion and spur with a hot bodies. Do I need to change the diff housing or just the pinion and spur?

do you mean the pinion and ring gear? im pretty sure that you can use the same cups.

yeah squee. The ring and pinion. some call it spur some call it ring. but the one that goes to the diff housing. I want to make sure before I get them.

im pretty sure they will because if im not mistaken they use the same cases.

Thanks squee. I may have to order the ring and pinion and see. I have to let you know more on the trial fit.

That is doable Coolhand, they use the exact same diffcup.

You need another gearing with the 2250?
