Fitting Advice for Tuners

Before assembly, remove any dirt or old lubricant from the gearbox and test mesh by hand. Proper alignment and a careful break-in help extend service life. Check the gear periodically and swap it out if you find excessive wear.

The gear fits the Viper 989 GP regardless of surface, but gearing choices and maintenance routines may differ between road, carpet, and dirt.
Use a light, appropriate gearbox grease to protect contact surfaces. Avoid heavy pastes that can slow shifts or trap debris.
Look for rounded or chipped teeth, discoloration from heat, or rough engagement when shifting. Any of these signs suggest replacement.
Yes. Inspect hubs, shafts, and bearings for wear, since worn parts can accelerate gear damage. Replace worn components together for best longevity.
