what breaks on a pro 4..... well.....
Caster blocks and front hub carriers mostly. A front arm or two if you hit hard enough, but they are pretty tough.
Unless you get a BRP tc3 front bumper, drill some mounting holes, and run it. Then you don't break much.
what mods are needed to the drivetrain?
None. Shim the diffs properly and put it on the track. best shaft drivetrain ever IMO.
