Are you lookig for Shaft driven or independent?

Clods are probably the best independant motor axels. They are very beafy. and can easily be used on an 1/8th scale truck.

These are Shaft drien... TXT and twin force axles are larger then the TLT axles and are about the same size as the Clods. TLT axles are great but in my opinion a little small (Narrow) to pull off a nice looking 1/8th scale. I can practially fit my TLT between the wheel base of my clod.

Hope that helps...
