Will these fit standard HPI Baja motor shafts?

Yes, the pinions use a 5mm bore to match standard HPI Baja motor shafts for straightforward installation.

How do I set gear mesh with these steel pinions?

Start with a small paper shim between pinion and spur, tighten the motor mount, then rotate to check for smooth mesh and a light amount of backlash to prevent binding.

Are both gears hardened for heavy use?

The gears are steel and intended for increased durability compared to stock zinc or nylon pinions, making them better for high-load running.
