Is this compatible with my RB7SS transmission?

Yes, the UM730-69B is specified for RB7 and RB7SS transmissions. Confirm your chassis uses the standard 48P spur configuration before fitting.

Will it affect motor temperatures?

Gearing itself does not drastically change motor temps, but selecting the right pinion to match the 69T spur can influence load and heat. Monitor temps when changing gear ratios.

Recommended upkeep between races?

After sessions, clean the spur of debris, inspect for chipped teeth, and apply a light film of gear lubricant to protect contact areas and extend life.
