Will this shaft fit factory TRX4 axles without modification?

The shaft is designed for the TRAXXAS TRX4 and fits standard axle housings; minor trimming of body clips or links is rarely needed depending on your setup.

Should I pair this with heavier wheels or tyres?

The alloy body and steel shaft handle typical crawler wheels and tyres, but check link angles after fitting heavier tyres to avoid binding.

Any tips for maintaining the adjustable range?

Keep the o-rings clean and lightly lubricated, and periodically check the screw shafts for tightness to preserve adjustment accuracy.
