It is extremely strong, but it uses large bearings around the outdrives, and it uses regular traxxas 4wd diff parts for the inside (i.e. the bevel and spider).

Note that it only uses 2 spider gears (vs 4 in the proline diff) but the build quality is excellent. The diff case is very heavy relative to normal diff cases.

I tried the proline diff for quite some time and either the case or the diff would always fail.
