Is this suitable for short course trucks?

If the short course truck uses 48 pitch gearing, this 79T spur will fit and can give a smoother drive feel, though final choice depends on your gear ratio preferences.

Will it affect gearing range?

Moving to a 79T spur alters the overall ratio compared with lower tooth counts, so you may need to adjust the pinion to retain the same top speed or acceleration characteristics.

Any tips for fitting?

Set the mesh with a feeler or paper method, secure the spur with the correct bolts, and check for binding across the full suspension travel before running at full power.
